Egypt. It is amazing.

Egypt. It is amazing.

by Douglas Yeo (February 5, 2026)

It was 1963—I was eight-years old. While visiting my grandparents, I picked up a copy of National Geographic Magazine, dated October 1963. Yes, I read National Geographic when I was eight-years old. When I held a copy of the magazine in my hands, I was always transfixed.

The cover of that issue had two photographs: a man ascending to the summit of Mount Everest, and the golden mask of Tutankhamun. I started reading. The article about Mount Everest was dramatic and thrilling. But Tutankhamun’s golden trove of treasures? I was entranced. The issue also had a map of “Countries of the Nile.” I studied it for hours. Egypt had me in its grasp.

National Geographic, October 1963

A few years later, in May 1966, I read another issue of National Geographic. The article, “Saving the Ancient Temples at Abu Simbel” got my attention. Ancient monuments in Egypt that were soon to be under water with construction of the Aswan High Dam? And people were going to cut the monuments apart, build a new mountain, move the pieces to the new location – 100 feet higher so they would not be under water – and put them together again? It sounded impossible.

National Geographic, May 1966 and May 1969

But the May 1969 issue of National Geographic was triumphant: I read another article (you are getting the idea: I love to read), “Abu Simbel’s Ancient Temples Reborn.” I wanted to go to Egypt. I had to go to Egypt. I wanted to see this with my own eyes. As the years went on, my desire to visit Egypt increased, in part because in 1976, my grandmother – she with the National Geographic magazines – visited there. 

It took over 60 years since Egypt first came to my mind in 1963, but last month my wife, Pat, and I went to Egypt. It was a remarkable, transformative trip.

Arizona State University Alumni Travel/AHI Legends of the Nile brochure

In fall of 2025, I received a brochure from Arizona State University alumni travel. I didn’t graduate from ASU but from 2012–2016, I was ASU’s full-time Professor of Trombone. Those were wonderful years of teaching with engaged, talented students, and working with superb colleagues. I still have a courtesy affiliation with ASU and as a result, I receive mailings from the University from time to time. Like a brochure about a tour of Egypt, “Legends of the Nile,” with AHI Travel.

It took Pat and me fewer than 24 hours to decide to join the trip. The itinerary checked every box on my life-long imagined trip to Egypt. With a highly reputable tour operator, AHI, first-class accommodations, a superb Egyptologist, Raffat Khatab, and a truly remarkable tour director, Ashraf Masoud, the trip promised a memorable experience. But I was wrong. It wasn’t memorable: It was life-changing.

Here are a few of the highlights, many photos with commentary that just scratch the surface of our trip. Unless otherwise noted, all of the photographs were taken by me:

The Grand Egyptian Museum, Giza

Pat and I decided to go to Egypt a day earlier than the group so we could have an extra day to explore the Grand Egyptian Museum (GEM). We’re so glad we did. Years in the planning, the museum had a soft opening a few years ago but the most remarkable of its galleries – the ones with all 5,000+ treasures from the tomb of Pharaoh Tutankhamun, were not yet open. That had to wait for the grand opening of the museum that was delayed multiple times. Happily, the museum fully opened in November 2025, in time for us to visit.

Gallery Guides for the Grand Egyptian Museum, Giza

Our day at the GEM was eye-opening. We had tickets to start our visit at 11:00 am. Thanks to Ashraf and his massive portfolio of connections – really and truly, I believe he knows everyone in Egypt – he arranged for us to enter the museum at 8:30 am, before the official opening time. We stood astonished at the huge statue of Pharaoh Ramesses II (carved from a single piece of red granite) in the museum’s courtyard:

We were ushered to the Tutankhamun galleries where we viewed the iconic golden mask – by ourselves. A private viewing. No crowds. Amazing.

National Geographic magazine came alive:

We spent two hours with “King Tut.” We marveled at his golden throne:

All three of his golden coffins:

His golden chariots:

Jewelry, jewelry, and more jewelry:

And something that was very, very important to me, the oldest surviving metal ancestors of the trombone, the two trumpets that were discovered in Tutankhamun’s tomb, along with the decorated wooden inserts that were kept inside the bells to keep them from being damaged when they were not in use:

The museum had more. Much more. The Grand Egyptian Museum was overwhelming in its scope of Egyptian history. Statuary abounds, and the descriptive labels were always informative.

We saw the “solar boat” of Pharaoh Khufu, found buried next to the Great Pyramid.

After our visit to the Grand Egyptian, we went to the Egyptian Museum. Built in 1901 at Tahir Square, Cairo, it still houses many important pieces of Egyptian history that have not been transferred to the new Grand Egyptian Museum.

The museum’s collection included one of the most important part of Egypt’s history, the Narmer palette, showing Narmer, the first King of a united (upper and lower) Egypt, dating from about 3200 BC.

We returned to the Grand Egyptian Museum again the following day with our whole tour group — we were so glad we had gotten to Egypt a day early so we could enjoy this remarkable museum twice.

The rest of the tour unfolded like a National Geographic television special, but in real life. We visited Saqqara, where the first pyramid (a step pyramid, build for the Pharaoh Djoser around 2650 BC) was constructed:

Then, we visited the Pyramids of Giza. I don’t know if there is anything in the world more iconic than the Giza Pyramids.

Our tickets to enter the Giza Pyramid area

We went inside the Great Pyramid of Khufu. There isn’t much inside – only the broken, empty sarcophagus of Khufu. Still, it was a thrill to be INSIDE the last surviving wonder of the ancient world. Getting to the burial chamber of the Pyramid was a real adventure through narrow tunnels.

No photograph in a book prepares you for the monumental size of the Great Pyramid. It is 480 feet tall, and each side is 756 feet long. Think about that. Each side is longer than two football fields. It truly boggles the mind – and we still don’t know exactly how they were constructed. Seeing these amazing structures was thrilling beyond words.

I’ve always loved “before and after” photographs. Many individuals in the nineteenth century captured some of the ancient monuments before they had been restored, or when they were partly – or mostly – covered with sand. Francis Frith took many photos in the 1850s and throughout this blog post, I’ll include some of his images next to my photos. The comparison is striking.

I have to say, though, seeing the Pyramids was even more thrilling when seen from the back of a camel. Seriously!

A visit to the iconic Sphinx was a thrill. The main body and head were carved from a single piece of rock that was already there at the site.

After we visited the Sphinx, I sent some photos to our daughters, who have cats. One of them sent us this composite, below. I guess cats are cats, even if they have a human head!

I think that one of the things about this trip is that when we saw Egypt up close – whether we saw huge monuments or items in museums – our sense of scale was enlightened. When you see photos in a book, everything looks the same size. When you see them up close in person, you see them as they really are.

While in Cairo, we spent a day visiting Coptic Christian churches and Muslim mosques, as well as the oldest synagogue in Cairo (photography was not permitted in the synagogue). Given the many references to Egypt in the Bible – Moses before and during the Exodus, Jesus, Mary, and Joseph on their flight from the slaughter of the innocents by King Herod – as well as the life of Saint Mark (who was an Egyptian and wrote the Gospel of Mark), we found this day’s excursion to be fascinating. 

The (Coptic) Cavern Church of Saints Sergius and Bacchus (Abnu Serga), Cairo. This church was built on a traditional site where Jesus, Mary, and Joseph stayed while in Egypt.

From Cairo, we flew to Luxor to begin our cruise up the Nile River (remember that the Nile flows from south to north, so upper Egypt is in the south and lower Egypt is in the north). On our way to Cairo airport, Ashraf had a surprise for our us: we stopped by the grave of President Anwar Sadat and Egypt’s Tomb of the Unknown Soldier. This powerfully moving site is across the street from the place where Sadat was assassinated in 1981 while viewing a parade. Sadat was a courageous hero who, along with Prime Minister Menachem Begin of Israel and President Jimmy Carter of the United States, was a signatory to the Camp David Accords and the Egypt-Israel peace treaty in 1978. Sadat and Begin shared the 1978 Nobel Peace Prize.

The grave of Anwar Sadat, Cairo. The inscription, in Arabic, reads:

In the name of God, the Most Gracious, the Most Merciful

“And do not think that those who were killed in the path of God are dead.
Rather, they are alive with their Lord, receiving provision.”
(Qur’an 3:169)

God Almighty has spoken the truth.

Looking across from Anwar Sadat’s grave to the site of his assassination in 1981.

Luxor is home to the Luxor Museum and many ancient Egyptian sites, including Luxor Temple. Once again, we were fascinated by the sculpture in the museum. We sailed by felucca (boat) to Luxor Temple, enjoying sunset along the way. Luxor Temple was our introduction to the many huge temple complexes in Egypt. The carving, the architecture, and the sheer scope and scale of the complex is tremendous.

Luxor Temple used to have two obelisks, one on either side of the entrance to the temple. In August 2025, Pat and I traveled to Paris to celebrate our 50th wedding anniversary and saw the other Luxor obelisk, erected at Place de la Concorde, the site of the guillotine used during the French Revolution. It was given to France in 1830 by Muhammad Ali Pashar and installed in 1836.

From Luxor, we traveled to the Valley of the Kings and Valley of the Queens. The highlight of this excursion was seeing the tomb of Tutankhamun. Having seen the treasures from his tomb at the Grand Egyptian Museum in Giza, seeing his tomb – and seeing how small it was – was enlightening. Tutankhamun’s mummy and his granite sarcophagus are still in the tomb, along with the brightly painted walls. Having read many books about Tutankhamun and his treasures, seeing his tomb in person gave us a memorable, unique perspective.

Who can forget the iconic “King Tut” routine by Steve Martin, from Saturday Night Live in May 1978. OK, it’s silly and irreverent, and it makes no sense (no, Tutankhamun was not “born in Arizona, moved to Babylonia”). But engaging with the REAL “King Tut” brought him from a comedy routine to a real person who lived and breathed.

The Mortuary Temple (Deir Al Bahari) of Queen Hatshepsut  – who ruled as Pharoah – is dramatically set under a high cliff. We also visited the Colossi of Memnon, huge statues of Amenhotep III that, having been toppled in earthquakes in antiquity, have been significantly restored.

Following our visit to the Valley of the Kings and Queens, it was time to board our ship – the Sanctuary Nile Adventurer – for our cruise up the Nile. We had never been on a river cruise before and all I can say is that this particular experience was memorable beyond words. We were greeted on the dock by a group of Egyptian musicians.

The food, the accommodations, the way the ship was laid out – everything was first class and beautifully, efficiently, and superbly done. Click HERE to see a video about the Sanctuary Nile Adventurer. The video is true to our experience. It was wonderful.

The following morning, I got up early to take a hot air balloon ride. I had never done this before – I’m not wild about heights but I figured that if I didn’t take advantage of this opportunity at this time, when would I ever do it? So I did. It was fantastic. I loved watching the balloon be inflated, and then silently floating above the Temple of Hatshepsut and other sites. Memorable.

We did so much more. So so so much more. We visited Karnak Temple, The Temples at Edfu and Kom Ombo, and the Temple of Philae:

We had a party on the ship where we all dressed up in traditional Egyptian clothes, the galabeya. Everyone got in on the fun and there was dancing, food, and a lot of laughter. The crew of the Sanctuary Nile Explorer was so great to all of us. The cruise was absolutely fantastic from start to end.

One night, the 1978 movie adaptation of Agatha Christie’s Death on the Nile was shown on board the ship. We watched it and then watched it again when we got home. It was so fun to view the movie – much of which was shot on location in Egypt at the Pyramids and Sphinx, Karnak, and Abu Simbel – knowing so much about the sites. And this was funny: In a scene early in the movie, Linnet Ridgeway-Doyle (played by Lois Chiles) and her husband, Simon Doyle (played by Simon MacCorkindale) ride horses from the Pyramids to the Sphinx. They stop at the Sphinx and then continue riding away. Only if you’ve been to Egypt will you laugh at the impossibility of the scene: After riding FROM the pyramids to the Sphinx, they continue riding off AWAY from the pyramids. But the pyramids are in front of them! Have a look at the sequence below. We still don’t know exactly how ancient Egyptians built the Pyramids. But Hollywood figured out how to move them!

Scenes from Death on the Nile (1978) 

But there was one more stop on our tour, and it was a highlight of the highlight of the highlight for me. Abu Simbel. This huge, remarkable monument to Ramesses II and his wife, Nefertari, was threatened with being submerged with construction of the Aswan High Dam. It was the moving of Abu Simbel – to dry land about 100 feet higher – that was one of the things that captivated me long ago while reading those issues of National Geographic magazine at my grandmother’s house. The size of the monument is truly breathtaking, and it’s nearly impossible to see the seams where it was cut apart and reassembled. I confess I got a little emotional at the sight. The Pyramids, King Tutankhamun’s treasures,  and Abu Simbel are three things I have dreamed about seeing for six decades. And I finally got to see them. Amazing.

These seated statues are 65 feet tall; by contrast, the monumental standing statue of Ramesses II in the courtyard of the Grand Egyptian Museum (shown earlier) is 36 feet tall. If the Abu Simbel statues were standing, they would be about 125 feet tall – the height of a 10–11 story building and taller than the Statue of Liberty (without its pedestal).

From Abu Simbel, we flew to Cairo and the next day, we flew home to Illinois. 

Throughout the trip, in the midst of all of the remarkable things we saw, experienced, and learned, my maternal grandmother was on my mind. Remember her, she of the National Geographic magazines I read in my youth? 50 years ago, in 1976, she visited Egypt. At that time, she seemed so adventurous to me, and her trip seemed so exotic. She loved seeing the world, and she went to some of its most interesting places. Greece and Rome, Egypt, safari in Africa, the Trans-Siberian Railroad, China, Machu Pichu, Easter Island, and Antarctica. Twice, because she loved penguins. She was an inspiration to me. She never took a camera on her trips; she always said her eyes and mind were the best camera. But I’m grateful that others on the tour took a camera and snapped a few photos of her. Because as Pat and I traveled through Egypt, we followed in her footsteps, a very precious memory of my dear grandmother:

This is the longest blog post I’ve ever written. Not because of the number of words in its text, but because of the large number of photos. But I have just touched the surface of our trip to Egypt. I took hundreds of photos and videos, but the most important images from the trip are the ones that are imbedded in my mind. My grandmother was right: photos don’t do justice to a place like Egypt. You have to be there and see things for yourself.

Many other experiences aren’t even mentioned in this post – visits to many more tombs, our visit to Chicago House of the Institute for the Study of Ancient Cultures at University of Chicago (that has been documenting inscriptions, carvings, and paintings in monuments in Egypt for over 100 years), the Aswan High Dam, a visit to a rug factory, an alabaster factory, the papyrus institute, the hotels, restaurants – the food food food! – the parties, the wonderful weather, the hotel and ship staffs, experiences with the new friends we made in our tour group, and much more.

Yet, after all of these words and photos, I have one more thing to say.

Legends of the Nile tour director, Ashraf Masoud (photo by Susan Throckmorton)

AHI planned a remarkable itinerary for us. Accommodations were first class. The food was outstanding. Service was superb in every way. But Pat and I reserve special thanks and praise for our tour director, Ashraf Masoud. 

Ashraf is an experienced world-wide tour director. That we had a director with such expertise didn’t surprise us; we expected that. But Ashraf was so much more. He enlightened us with information about aspects of Egyptian life and history that you would not find on an “average” tour or in a history book. As a native Egyptian – and as a world traveler – he has unique, personal insight. He shared that with us. We asked him thousands of questions. He answered every one. Questions about Egyptian life in the cities and the countryside, the educational system, the political system (past and present), and his hopes and dreams for Egypt. He was kind, gentle, generous, hard-working, imaginative, a problem-solver, funny, fun, serious, and helpful. I will never forget his booming voice when he called our group together – LEGEEEEEEENNNNNNDS! He was fair-minded and informative at all times. It seemed that he knew everyone in Egypt. Everywhere we went – everywhere – people met him with a warm embrace and a smile. He had connections and he opened doors any other tour director could not open. Ashraf’s humanity – his care and love for people – including us – came through every minute. We learned so much from him – about Egypt, Islam, Egyptians, and the world – that we simply would not have learned anywhere else. Over the course of our 12 days in Egypt, Ashraf became much more than our tour director. He became our friend. We grew to love this remarkable man, and he shared his love with us.

We miss Ashraf. We miss Egypt. Even though we’ve been home for over a week, Pat and I think and talk about Egypt throughout each day. Now, reminders about Egypt are all over our house – paintings on papyrus, alabaster, photos, and decorative trinkets. They make us smile. Egypt became far more than an article in a National Geographic magazine, or a headline in the news. It jumped off the pages and became real, with real people, real events, real history. I run out of superlatives when I try to describe the trip.

I want to go back. I want to see the sites all over again, sail on the Nile River, and see my friend, Ashraf again. You must go to Egypt. If you go to Egypt, the trip will CHANGE YOUR LIFE. If you have the resources for a first-class tour, consider going with AHI. And be sure to ask if Ashraf Masoud is the tour guide. He is the best of the best of the best.

Now that we’re back home, I am doing the many happy, engaging things that occupy my life including activities with our family and church, research, writing another book, teaching, and making music. More travels are ahead for us. I have no complaints; God is good. But these days, Egypt is always on my mind.

Perhaps the words written under the pyramids cakes that we enjoyed at our last dinner on the Sanctuary Nile Explorer will turn out to be a prophecy. Egypt: I hope to “See You Soon.”

Why trombone players cannot trust artificial intelligence (AI) for historical information

Why trombone players cannot trust artificial intelligence (AI) for historical information

by Douglas Yeo (December 17, 2025)

I am at work on a book for Oxford University Press, The Trombone Book, that will be part of OUP’s new series of books on musical instruments. This new series replaces OUP’s previous series of books on musical instruments that included Trombone Technique by my late friend, Denis Wick (London: Oxford, 1971) that has been out of print for several years. I am working up against several deadlines to get the book finished and submitted by the end of 2026, so I’m working on this every day. It’s slow going because I want the book to be helpful. And if it’s going to be helpful, it needs to be accurate.

Included in my new book are several chapters on the history of the trombone, its music, composers, and performers. I have over 2000 books in my library here at home, and I make ample use of inter-library loan (ILL, or ILLIAD), access to which is generously provided to me by the kind staff at the Library at my undergraduate alma-mater, Wheaton College. 

Two of the seven bookcases about composers, musical instruments, and other music related subjects in my home office. In our basement, I have many more bookcases full of books.

When it comes to historical resources, many have been scanned and are available on IMSLP  and Internet Archive. This is a tremendous resource for researchers, a real change from the microfilm/microfiche days of old. (I remember those days; it was not an easy time to do research.) When I can’t find a scan online, I acquire the book. If I can’t get the book through inter-library-loan, I purchase it. Even though many historical passages in treatises and methods have been translated into English by various authors (including David Guion, Howard Weiner, and Stewart Carter), I always want to see the original myself and do my own translation. In some cases, when I deal with old typography in various languages (16th through 18th centuries), it’s difficult to read, and artificial intelligence can be helpful in providing the original text in readable form. AI (I use ChatGPT 5.2, a paid service that is more advanced than the free ChatGPT 4.o) can provide a reasonably good text into modern languages from old typography, and it also reasonably translates text into English. In this, AI can be very helpful, However. . . after I read an AI-made translation, I always redo the translation myself and also confirm the translation with a native speaker of that language. Because I don’t trust AI. 

I have written about this previously on TheLastTrombone and if you haven’t read my article, ChatGPT and the trombone: Is this the end of writing and research? I don’t think so., please take a minute to do so. In that article, I fed ChatGPT several questions about the trombone and other musical instruments. The answers will probably surprise you but my conclusion should not: You cannot trust AI when it comes to the history of the trombone.

There are three reasons for this:

First, AI only knows what it’s been fed. If it’s been fed junk — older readers may remember IBM’s early motto, “GIGO,” or “Garbage In, Garbage Out” — it will spew out junk. Frankly, there is a lot of trombone research out there that’s pure junk. And AI has been fed a steady diet of trombone research junk. Why that’s the case is another story, but suffice to say that when I read something about the trombone in a book or article, I always look for the footnote and I track down the source myself. Because machines aren’t the only thing that get things wrong: human beings get things wrong, too, or they’re sloppy, or they don’t cite a source correctly, or they cite a secondary source that cites another secondary source and when you go to the end of the rainbow, there is no primary source. I wrote about this — people making up something and presenting it as true because they didn’t actually track down the original source — on TheLastTrombone when I discovered that the Pulitzer Prize Committee had mangled a quotation by Joseph Pulitzer ON ITS OWN WEBSITE. Read about that HERE, in my article titled, “Words matter.”

Second, AI is getting worse, not better when it comes to history. When it is asked questions, AI tries to answer them. It rarely says “I don’t know.” Instead, it feeds on previous answers it has given to similar questions, even if those answers were wrong. In time, like a game of “telephone,” AI ends up with something that’s wrong but sounds plausible. It always writes with excruciatingly accurate grammar and punctuation, even if sometimes the sentence structure it uses is a little over the top and a little cringeworthy.

Third, AI hallucinates. It makes up stuff. All. The. Time.

I’m taking time away from working on my book today to share a recent interaction I had with AI regarding a 18th century text about the trombone. I’m working with multiple sources at the same time and now and then, I get confused about where I actually got a source. I have hundreds of PDFs of articles, treatises, and methods in several languages. I have many screenshots I’ve taken of text that I’ve then uploaded to ChatGPT to put into a modern typeface so I can read it better.

Today, I was proofreading chapter 2 of my book, “A Brief History of the Conception and Evolution of the Trombone.” The first part of the chapter concerns many of the myths about the history of the trombone, myths that have been repeated over and over again in papers, dissertations, and books. Starting out with what’s wrong about how the trombone’s history has been told allows me to correct false narratives. It also gives me a good starting place to get back to ground zero and write something about the trombone’s history without the fog of mis- and dis-information that has affected trombone research for hundreds of years.

While I was proofreading, I came across an origin story for the trombone that I had included in my chapter — a false origin story. I recalled that I had read an English translation of the text I’m including in the chapter in a book, but I couldn’t recall where. My citation was for the original treatise; at least I THOUGHT it was the correct citation. But something in the back of my mind wondered if I had it right, so I re-uploaded the text to ChatGPT and asked what the source was. Here’s the text I needed to identify:

It’s the first paragraph that interests me. It’s a false narrative about the origin of the trombone. I translated it like this:

According to the testimony of Philo, the trombone was invented by the great, God-beloved prophet Moses, around the year 2400 of the world 200, just as Jewish writers ascribe the psaltery and cither to the first musician, Jubal. So, it is beyond dispute that the trombone is one of the most ancient  musical instruments. 

In my citation, I had given this as the source:

Johann Philipp Eisel, Musicus autodidactus, oder der sich selbst informirende Musicus (Erfurt: Wülfingische Buchhandlung 1738), 70.

But I wanted to be sure. So I asked ChatGPT. What follows are screenshots of my interaction with AI just a few hours ago, today, December 17, 2025. It begins with my uploading the passage (above) and my asking AI to identify it. I told AI that it had previously worked on this passage for me. My comments are on the right side of each screenshot, in a shaded box; ChatGPT is on the left:

AI identified the passage as from Daniel Speer’s important treatise Grund-richter Unterricht der Musikalischen Kunst (Fundamentally Correct Instruction in the Musical Arts) (Ulm: Georg Wilhelm Kühne; Christian Balthasar Kühnen sel. Erben, 1697). 

AI said it was NOT from Walther’s Musicalisches Lexicon. Walther’s book, Musicalisches Lexicon oder Musicalische Bibliothec (Leipzig: Wolfgang Deer, 1732). I don’t know why ChatGPT said the text was not by Walther. AI must have thought I might have thought the quotation was from Walther’s book even though I had not referenced that book in any of my previous interactions with ChatGPT. A red flag went up in my mind.

In any case, ChatGPT continued to explain its confidence in identifying the passage as by Daniel Speer. It wrote:

That sounds pretty confident. And raise your hand if that answer would be good enough for you to include AI’s attribution to Speer in your paper about the trombone. I see your hand up!

But I wasn’t so sure. This all sounded a little suspicious. AI didn’t give any REAL source for the attribution to Speer. It said the passage “is characteristic of Speer,” it is out of “Speer’s Biblical-historical framework,” “Josephus” appears in Speer’s work, etc. It didn’t seem right, even though it confidently told me where I could find the text in Speer’s book.  So, I asked AI to give me more:

First, here you can see the “fake news” in this passage, now that it’s translated into English. It cites the Hellenistic Jewish Philosopher, Philo of Alexandria, who, the passage says, testified that the trombone was invented by Moses — yes, THAT Moses, he of the 10 Commandments — in the year 2400 OF THE WORLD (not BC or AD, but OF THE WORLD) — and that “it is beyond dispute that the trombone is one of the most ancient musical instruments.” You can see why I’m including this text in my book where I talk about the myths of the trombone’s origins. It. Is. Not. True.

Second, ChatGPT’s translation of the passage into English is a little different than my own translation that I’m including in my book, as mentioned above. That’s because there are many ways to “do translation.” Word-for word, or thought-for-thought, or a combination. Once again, here’s my translation. It isn’t better or worse than the one that AI gave, but it’s a little more literal. The important thing is that the sense of the original comes through loud and clear and nothing new is added to the author’s intent:

According to the testimony of Philo, the trombone was invented by the great, God-beloved prophet Moses, around the year 2400 of the world 200, just as Jewish writers ascribe the psaltery and cither to the first musician, Jubal. So, it is beyond dispute that the trombone is one of the most ancient  musical instruments 

OK, back to AI. . .

I looked at my original citation for the text as I had written it in my book chapter. I had it identified as by Johann Eisel, as mentioned above. I was having doubts about Chat GPT’s confidence that the passage was from Speer, and I was gaining confidence in my original citation of Eisel.

I went back to my files and found Speer’s treatise. ChatGPT said the text in question came from page 221 of Speer’s book. I found the page; here’s what Speer wrote about the trombone on the bottom of page 221 and top of page 222:

Page 221 and 222 (incipts) from Daniel Speer, Grund-richtiger, kurtz-leicht- und nöthiger, jetzt wol-vermehrter Unterricht der musicalischen Kunst. Oder Vierfaches musicalisches Kleeblatt… (Ulm: Georg Wilhelm Kühne; Christian Balthasar Kühnen sel. Erben, 1697)

Here, below, is an English translation of these passages. You’ll notice that Speer is writing about the trombone in A, that the trombone has only three slide positions, and that alto, tenor, and bass trombone parts can all be played on a tenor trombone. I’m not going to unpack those things in this blog article; that’s a long conversation for another time (read about them in my book when it comes out!). Here’s what Speer wrote:

On trombones.

How does one ordinarily play a trombone?
A trombone is played by blowing and by means of the slide.

How many slide positions does a trombone have?
The principal slide positions of the trombone are in three places, apart from several others which should also be added.

Since on a tenor trombone one can play alto, tenor, and bass, this instrument shall therefore be described first.

First, one should know a trombone consists of two parts, namely the main section and the slide tubes, which lie within a sleeve. The main section is fitted onto the slide tubes, and the entire trombone is held with the left hand — a customary manner of holding which the instructor will already demonstrate to his pupil. With the right hand, however, one grasps the sleeve between the fingers.

This instrument has three principal slide positions. The first position is at the mouthpiece and consists of the following notes, as the appended example shows:

Interesting stuff, for sure. But there’s nothing on these pages about Philo. Nothing. Nothing about Moses. Nothing. 

So I questioned AI about this:

Well, AI sure put me in my place: “Your screenshot is not from Eisel.” That sounds pretty definitive. But I pulled up my sleeves. I was ready for battle.

“OK, machine,” I thought. “Game on.”

By then I knew I was right and ChatGPT was wrong. I remembered where I first saw the quotation: it is in David M. Guion’s book, The Trombone: Its History and Music, 1697–1811 (New York: Gordon and Breach, 1988; reprint, New York: Routledge, 2013). David’s book is invaluable for a lot of reasons, including the fact that he reproduces comments about the trombone from many historical books and treatises. I turned to page 41 of David’s book and found the passage in question in the original German alongside David’s translation to English. If you’re a trombonist and you don’t have this book, ask Santa Claus to bring you a copy, or get it from the library. Here’s the passage from David Guion’s book; this is where I first read about Eisel’s story about Philo and the supposed origin — NOT! — of the trombone:

Excerpt from David M. Guion’s book, The Trombone: Its History and Music, 1697–1811 (Gordon and Breach, 1988; reprint, New York: Routledge, 2013), page 41. 

As you can see above, David’s English translation is a little different than the one ChatGPT made and the one I made. All three give a good sense of the original. But even though David’s a really good researcher and scholar (and a fine trombonist, too), I wanted to see the original with my own eyes and make my own translation. I’ve seen enough instances where someone has missed a word—I’ve done it myself. It’s really important to me to get to the original source if I can find it. So I went looking for Eisel’s original. 

Now it was time for me to ask ChatGPT another question. It had hallucinated — it had made up that the passage was by Speer. I wanted to know why, and I let the machine have it right between the eyes—or between semiconductors:

It took 44 seconds for ChatGPTto “think” and then write one of the most difficult sentences in the English language: “You’re right, and I was wrong.” AI went on to explain WHY it was wrong. Its answer was revealing. It didn’t check for the source of the quotation in question. It used a pattern-matching algorithm to attribute the quotation to Speer. Further, it was “overconfident.” When I challenged the attribution, instead of checking again, AI argued with me. It thought it knew the right answer and I didn’t. But AI was wrong.

I wasn’t going to let AI off the hook. In hopes that this “conversation” with a machine might help it make better decisions in the future, I scolded ChatGPT:

OK. A gold star for Douglas Yeo. A failing grade for ChatGPT. But, actually, this isn’t funny. This kind of thing goes on ALL THE TIME. ChatGPT’s conclusion is actually exactly correct:

If AI is to be useful in serious scholarship at all, it has to be treated — and behave — as a fallible research assistant, not an oracle.

Yes. Read these words over, and over, and over. This is important.

I hope that this short diversion from my afternoon of working on my book is both revealing and helpful to readers who engage in research and writing. AI is really useful for a lot of things. But it is also really BAD for a lot of things. We simply cannot rely on it for historical information. As AI tools evolve, they are getting more and more confident. That confidence is often misplaced. As I said earlier, AI’s answers often are like a game of “telephone.” Over time, AI’s overconfidence causes it to use its own hallucinations and misinformation and pile it on top of other misinformation on top of other misinformation. When dealing with AI, we are wise to employ the same phrase that Ronald Reagan used when he was negotiating a nuclear arms reduction  treaty with the Soviet Union in the 1980s: “Trust but verify.” 

The importance of getting trombone research right isn’t on the level of working to prevent nuclear war. But for a student who relies on AI, the consequence of a failing grade, or being responsible for continuing to perpetuate falsehoods, ought to be enough to cause one to think twice, then three times, then four times, or seventy-times-seven times before trusting anything AI delivers. If you’re a college professor, please consider forwarding this article to your students and on your social media platforms. We must recognize the limitations of artificial intelligence. We must get the world out. As ChatGPT said:

AI is a fallible research assistant, not an oracle.

That’s the most accurate thing I’ve heard from ChatGPT in a long time.

A dragon-bell trombone solo x one million people

A dragon-bell trombone solo x one million people

by Douglas Yeo (December 13, 2025)

I don’t use any form of social media – Facebook, Instagram, and all the rest. I have my reasons for this but I understand that many people find it useful and helpful. Actually, there was a short time in my life when I did use Facebook. That was during the years I was Professor of Trombone at Arizona State University, 2012–2026. At that time, a Facebook page for our trombone studio was a great way to get out the message of what we were doing at ASU. It also was helpful for recruitment, and parents always seemed to enjoy the photos and videos I would post that included their children. But that was it for me and social media – when I retired from ASU, that was the end of my social media engagement.

Now and then, a friend or colleague will reach out to me and let me know that someone posted something about me, and now and then I hear from people who tag me on social media, wondering why I didn’t respond to them. Well, I don’t use social media; I never saw their tag!

Segue: Last week, I (Douglas Yeo) visited my friend, Dana Hofer, who owns Dana Hofer Brass Repair in Des Plaines, Illinois. He is the go to person for brass players in the Chicago area when they need an instrument fixed. Since we moved here in 2018, I’ve made many trips to his shop to get various instruments repaired. He’s a great technician, a decent, honorable, fair-minded person, and runs his business like he cares for and about his customers and their instruments. Because he does.

Earlier this year, I acquired a bell to a 200 year old buccin, a “dragon-bell” trombone made by Jean-Baptiste Tabard in Lyon, France. Tabard was active as a maker in the early nineteenth century and the buccin was popular in French military bands at that time. I’ve written about the buccin on TheLastTrombone. I recorded a video of me playing a buccin by Tabard at the Museum of Fine Arts in Boston. I’ve also written the entry about the buccin for The Grove Dictionary of Musical Instruments and several other publications.

The logo of the International Trombone Association, based on a buccin by Tabard owned by New England Conservatory of Music in Boston, Massachusetts.

And. . . the buccin is the official logo of the International Trombone Association. That logo appears on the plaque I received in 2014 when I received the International Trombone Association’s ITA Award. It hangs on the wall above the desk where I am writing this blog post.

At its founding in 1972, the ITA adopted a stylized buccin logo based on a buccin in the collection of New England Conservatory of Music in Boston, where I taught for 27 years when I was a member of the Boston Symphony Orchestra. And the maker of NEC’s buccin? Tabard. So, now I own a buccin that is a cousin to the one at New England Conservatory of Music, and the ITA’s logo has even more meaning to me.

The buccin bell I recently acquired was in very rough shape when it arrived on my doorstep. It was heavily dented, it was missing a brace, another brace had come loose at its flange, and it was covered with two centuries of patina and grime. But I knew that the right person could resurrect it. I asked Dana if he could restore the bell so I could play it. He agreed, and last week, he called and told me it was ready. I went to his shop to pick it up.

I love playing the buccin. I think it’s the coolest trombone ever made. It’s wonky looking and wonky sounding. And because the bell is over your head and not in front of you, you don’t have the bell as a guide to find slide positions. Imagine playing trombone with your eyes closed. That’s how you REALLY get to know the trombone. Playing it is a really fun challenge.

When I dropped the bell off for Dana to restore, I gave him a slide to my other buccin bell by François Sautermeister of Lyon, a slide that had been made for me by Jim Becker (formerly of Osmun Music in the Boston area, now with YAMAHA in New York City). I asked Dana to make a new receiver for that slide so it would fit on my newly acquired Tabard buccin.

When I saw my buccin at Dana’s shop last week, I was absolutely thrilled with his restoration. The dents were gone, a new brace was in place, the centuries of grime had been removed and I had a beautiful instrument in my hands. Here are some “before and after” photos:


Of course, I wanted to play it right away. After tooting a couple of arpeggios – and noticing that it played in A, not B-flat – Dana said, “Hey, let’s make a video for Instagram.” “Sure,” I said. Dana gave his iPhone to Sam Park, who works with Dana at the shop, and Sam took a video of me playing “We Wish You A Merry Christmas.” It was the first piece I’d ever played on the buccin and that was that.

It was over in 30 seconds. I went home and moved on to some other things.

A little later in the day, Dana texted to say he had posted the video on Instagram and Facebook. If you want to see the video, go to Dana Hofer Brass on Instagram, or Dana Hofer Brass Repair on Facebook. I also put it on my own YouTube channel so I could link the video to this blog post. Here’s the video:

Two hours later, Dana texted me again with a screenshot of his Instagram feed. He wrote:

Just so you know, the Instagram is blowing up. These are pretty high numbers for me.

The video had 13,400 views in two hours. I shook my head. I don’t know how Instagram works, but that seemed wild. Over the course of the week, the numbers kept climbing. Then, this morning, December 13, 2025, Dana texted me with an update and he sent me a message with the screenshot below:

Looks like we might hit 1 million today.

The Instagram feed for Dana Hofer Brass, 11:01 am, December 13, 2025. 997,000 views. Dana Hofer on the left; Douglas Yeo on the right.

Seriously? 997k views? 997,000? Nearly a MILLION views of this video? With 60,800 “likes” and 29,100 shares? I couldn’t believe it. 

Sure enough, the video hit a MILLION views this afternoon. Here’s a screenshot Dana sent when the video hit that milestone:

The Instagram feed for Dana Hofer Brass, 12:56 pm, December 13, 2025. 1 million views.

There you go. 1M. 1 million people have watched me play “We Wish You a Merry Christmas” on a two hundred year old buccin. That. Is. Bonkers. You never know when something like this will happen. I was just trying out my new/old trombone. I wasn’t looking for a global audience. I wasn’t planning to play for one million people. And full disclosure: There’s nothing in this for me; there’s no money involved. But I’m thrilled that the buccin has a new audience, and most of all I’m happy for the publicity this has generated for Dana Hofer and his shop. A happy result of this is he’s gained hundreds of new followers for his Instagram and Facebook accounts, and if that results in more people using his services, that’s great news. If you’re in the Chicago area and you need a terrific brass instrument repair person,  Dana Hofer — Dana Hofer Brass Repair — is the person you’ll want to see.

Merry Christmas and Happy New Year to you, friends—all 1 million of you—from Dana Hofer, my buccin, and me.

100 years ago today – Rochut, Brahms 1, and the Boston Symphony Orchestra

100 years ago today – Rochut, Brahms 1, and the Boston Symphony Orchestra

by Douglas Yeo (October 9, 2025)

Readers of The Last Trombone know something about the life and work of the French trombonist, trombonist Joannès Rochut, who was principal trombonist of the Boston Symphony Orchestra from 1925–1930. I have written several articles about Rochut—who is best known for his influential books for trombone, Melodious Etudes for Trombone, arranged from the Vocalises of Marco Bordogni—here on The Last Trombone. You can find those articles here:

In addition, I wrote a 70 page article about Rochut’s life and work, “More than Bordogni: The Life, Work, and Influence of Joannès Rochut,” that appeared in the January 2025 International Trombone Association Journal.

Today, October 9, 2025, is the 100th anniversary of the first concert that Joannès Rochut played with the Boston Symphony. Here is the program and the list of orchestra personnel from the concert:

Here is a photograph of the Boston Symphony Orchestra, taken in fall 1925. Joannès Rochut is in the back row of the orchestra just in front of the right side of a doorway that’s in the center of the back wall of the stage. To his left are assistant principal trombonist Eugène Adam, second trombonist Lucien Hansotte, bass trombonist Leroy Kenfield, and tubist Paul Sidow.

This anniversary means a little more to me than the fact that I have been fascinated with Rochut’s life and work for over 40 years. That’s because he and I share a connection to our first opening night programs as members of the Boston Symphony Orchestra.

On October 1, 1985, I played my first opening night concert as bass trombonist of the Boston Symphony Orchestra. I joined the BSO in May 1985 and played several weeks of the 1985 Boston Pops season and all of the orchestra’s 1985 summer season at Tanglewood. But opening night of each Boston Symphony season was always a special event. As you can see from the program below, Rochut’s first opening night concert with the Boston Symphony Orchestra and mine shared something: we both played Johannes Brahms’ Symphony No. 1 on the concert. He was conducted by Serge Koussevitzky; I was conducted by Seiji Ozawa.

I don’t have a photograph of the Boston Symphony from my first full season with the orchestra, 1985–1986. But here is the earliest photo I have of the orchestra after I joined, taken in Symphony Hall during the 1987-1988 season.  The trumpets and trombones are along the back wall of the stage (left to right): assistant principal trumpeter Timothy Morrison, second trumpeter Peter Chapman, principal trumpeter Charles Schlueter, principal trombonist Ronald Barron, second trombonist Norman Bolter, bass trombonist Douglas Yeo, and tubist Chester Schmitz.

There you have it. Two opening night Boston Symphony Orchestra concerts, 65 years apart. Both concerts were in Symphony Hall, Boston. One common piece, the Symphony No. 1 in C minor of Johannes Brahms. And two new members of the trombone section, Joannès Rochut and me.

This makes me smile.
