First came across this piece while reading Haruki Murakami’s Kafka on the Shore (which everyone, and I mean everyone, should read). Beethoven (not the dog) was one of the in-betweens of the Classical and Romantic era, and that’s quite evident in this piece: you have the lightness and clarity of the Classical period, evident in the structure, the lilting phrases and the call-and-response/counterpoint melodies between the instruments, but at the same time it’s got that Romantic emotion and depth, a definite personality that I find a lot of Classical music lacks. Much of the latter seems so frivolous, too much lightness and la-di-dah – all those regular phrases and chords, 17th-century symmetry and poppy melodies! (Not Mozart and a few others. But Pachelbel, I’m lookin’ at ya.)

I feel like this is more of a Brett!Holmes piece than BBC!Sherlock – if you’ve seen/heard Brett on the violin (well not actually playing, but doing a pretty damn good job of pretending), all romantic and soulful, you’ll know what I mean. The first movement, especially – fluid melodies and all that. Him listening to this, waving his long fingers in the air in time to the music, a dreamy look on his face, and all that. For a technical description of this piece, look no further than the Kennedy Center’s writeup.
Here’s the description from Kafka on the Shore, the one that gets mentioned in the comments section for almost every rendition of this piece on YouTube:
“Hey,” he called out to the owner. “What was that music called again? I forget.”
“Beethoven’s Archduke Trio.”
“March Duke?”
“Arch. Archduke. Beethoven dedicated it to the Austrian archduke Rudolph. It’s not the official name, more like the piece’s nickname. Rudolph was the son of Emperor Leopold the Second. He was a very skilled musician, who studied piano and music theory with Beethoven starting when he was sixteen. He looked up to Beethoven. Archduke Rudolph didn’t make a name for himself as either a pianist or a composer, but sort of stood in the shadows lending a helping hand to Beethoven, who didn’t know much about getting ahead in the world. If it hadn’t been for him, Beethoven would have had a much tougher time.”
“Those kind of people are necessary in life, huh?”
“Absolutely.”
“The world would be a real mess if everybody was a genius. Somebody’s got to keep watch, take care of business.”
“Exactly. A world full of geniuses would have significant problems.”
“I really like that piece.”
“It’s beautiful. You never get tired of listening to it. I’d say it’s the most refined of all Beethoven’s piano trios. He wrote it when he was forty, and never wrote another. He must have decided he’d reached the pinnacle in the genre.”

don’t mind Jeremy… we just needed him lusting after Watson his face here.
Daniel Barenboim, Pinchas Zukerman and Jacqueline Du Pré’s version is decent - measured and stately; Jacques Thibauld is absolutely golden on the violin here. My favourite rendition of this piece is by the Gryphon Trio, which I last heard while flying British Airways. But I can’t find it online – so I hope you enjoy this version by Jos van Immerseel, Vera Beths, & Anner Bylsma. A pianoforte instead of a piano is used here, which works surprisingly well.
