About four years ago I made an episode about Bach’s ‘longest’ piece:

Somehow I missed a piece which should definitely be in contention for his ‘longest.’ At 437 measures, the Toccata in F, BWV 540, is (I think!) the longest stretch of Bach’s music, in terms of measures. It probably also holds the record for longest single note. Take a look at page one— an inanimate object could play the pedal part on page one:

From easiest pedal page, to tap-dancing nightmare, the feet on the very next page:

…and all that happens twice. What a piece! Over 170 measures of pedal drones and pedal ballet before this piece finally gets modulating. An arpeggio motif (what I call the spiral in the episode) gets passed through each voice, high to low:

These arpeggios occur in all major keys but one, and many minor keys. How’s this for tonally exhaustive?

Bach eludes the expectations of the listener three times in stunning deceptive cadences, after which, the B-A-C-H motif appears (in transposition) in the pedals:

If you play this piece, you’ll face the issue of whether or not to play the high D. The organs lacked this high D, but did Bach want this effect anyhow?

Ullrich Böhme’s excellent rendition (with fugue!)

Thanks for listening. Thank you for tuning in. I think you’ll be blown away by today’s piece, perhaps the longest piece. What is Bach’s Longest Piece and His Shortest? Probably not, but what I was really After was the longest uninterrupted stretch of music. So it seems like you could count that in two ways. The longest amount of measures or the longest amount of beats. And as I found going through the entire oeuvre or trying to count every single... There are a half dozen pieces that contain over 400 measures, and that’s massive, massive in terms of measures or bars, but all of these pieces are in the quick meter of 3.8. So if it’s actually pulses we’re after, then you see any piece that’s in 4.4 has more than twice the amount of beats than a piece in 3.8. So I don’t understand how to count this. This whole exercise became very superfluous and probably not very meaningful, but I did forget. Somehow I missed this one piece, today’s piece, this Toccata, that actually does, I think, I think unless I’m missing another one, this actually does have the most measures in any piece of Bach. It is 437 bars long. That’s a full 10 bars longer than the previous record holder, the piece that I thought had the most measures in that episode from 2022. But this piece, this Toccata, also holds some very interesting... This has the longest pedal point, I believe, the longest single sustained note in all of Bach’s music. If you look at the first page, I will show the image in the Substack description, you’ll see the first This page is nothing but a giant pedal point. Your left foot is stuck down to this pedal note, holding a note for 54 measures. That’s longer than most pieces, 54 measures. And here you are just holding one note. If you play the piano, for example, if you’re not comfortable playing with your feet on the organ, but if you do want... To feel the experience of playing one and a half pages of Bach’s organ music with not much trouble, start here. Your left foot just simply holds one note for one and a half pages. So this is the Toccata in F Major, BWV 540. It belongs to a Toccata in Fugue. We’ll do the Toccata today, the Fugue later. But here I want to zoom out. I tried to make this episode last week. I don’t know, I was working half the day and it just sort of fell apart. I try my best to be like a storyteller with Bach and for some reason my narrative was off. It just sounded like I was saying and then this happens and then this happens and then this happens and then this happens. Even I was losing the plot. I listened back to it and I was sort of overwhelmed. So I scrapped the entire episode and I’m starting again from a new vantage point. So sorry for no episode last Tuesday. That’s why. Let’s try this. This piece, this giant piece of 437 measures is a conversation between two shapes. One is short and the other is a long shape. So heading over to the organ here, the short shape is like this. This is an arpeggio or a spiral. It’s brief. And it will come in many different keys. The longer shape is more snake-like. It’s like this. You’ll be amazed to see how long this snake can grow. The conversation of these two ideas lasts for 437 measures of essentially an uninterrupted stream of 16th notes, a gigantic river of these 16th notes stopping only a few times to be punctuated with some really stubborn 8th note chords like this. These eighth note chords will sort of be alarmingly halting. It’s like when you’re on a long run or a long bike ride or something and then you have to stop at a crosswalk. That’s how this feels. But those three things are the entire piece. If you can hold on to those three things, you’ll be fine while listening to this piece. So it’s the spiral, the snake, and the eighth notes. You might be asking, but what about the pedal points? Well, this piece is flanked by those pedal points. Two giant pedal points, which began the piece, and two shorter pedal points, which end the piece. And in between, we have the fast succession of those three Those three ideas don’t really get talking until well into the middle of the piece. So now, like Milton, I’m going to start in medias res, in the middle of things. I’m going to start at bar 176, where the short shape... It comes in for the first time, and I’m going to play only the sixteenth notes of the short and long shapes. You can hear how this piece is that constant stream of sixteenth notes, and I’ll play the stubborn eighth note chords when they come in. This is like an outline. It’s everything that happens in the piece, and then we’ll go back and fill it in. The short shape in the pedals. Soprano, alto, tenor, pedals. Again, soprano, alto, tenor, Pedals. Again. Pedals. One more time. Maybe two more times. Pedals. Soprano. Alto. Tenor. A bit longer. Now here are the eighth notes.

Now here’s a surprising chord. Very surprising chord. Again, more spirals. Now here’s our long shape. First time we have the long shape from top to bottom. Into the pedals. Now eighth notes. And the snake. Right hand. Into the left hand. Into the pedals. Climbing up. And now conversation. Left hand. Right hand. Now pedals and left hand. Two lines together. We’re coming out of the snake into the spiral. Here starts the spiral. Soprano, Alto, Tenor, Pedals. Soprano, Alto, Tenor, Pedals. We’re modulating through all kinds of keys again. E major, pedals, all the way to the top. Soprano, Alto, a longer line now. Eighth notes again, here they are. No weird chord, no weird chord, straight into the snake. Left hand, pedals. Right hand. Pedals, left hand, right hand and pedals, two at the same time. Left hand, right hand, we’re coming out of the snake into the spirals again. Soprano, alto, tenor, pedals, over and over. Again, soprano, pedals. Soprano once more. Here come the eighth notes. And we are going to have a strange chord. How strange? Spirals. More spirals. And now the snake from top to left hand to pedals. Eighth notes, now the snake in the pedals. In the right hand. In the left hand. The conversation, right hand. Pedals, now two, right hand and left hand. Now here’s the craziest scale you’ve ever heard. Coming out of the snake into the spiral. Soprano. Alto. Alto. Tenor. Pedals, you get it by now. Soprano. One more time, and then all of a sudden we find ourselves here in B-flat major in the subdominant, and this is our penultimate pedal point. So we’re back to the pedal points that flank the entire piece. That is a lot, right? But that is the dark meat of the piece. After this, these pedal points that surround it are just pure joy, just fluffy dessert surrounding that very dense nutrition. Imagine playing this music over the grave. No pressure, no pressure, just Bach is buried beneath, probably listening to all your mistakes. I’m going to play the parts I just dissected and see if you can identify the three motifs at play, the eighth notes, which Those are the easiest to hear, you can’t miss those really. The spiral, the arpeggios, going from soprano to alto to tenor to pedals, a little easier to hear. And the snake motif, these longer lines, can you hear that too? Any music that you think, hmm, I’m not sure which music that is, that’s the snake. Weaving his way in and out of all the parts, sometimes you can see him darting under the grass, appearing from behind the alto lines, sneaking under the tenor. And with that small amount of stasis, that B-flat pedal point, we get to the penultimate pedal point again, and we are now out of the thick of the piece. That is more than half the piece. By the way, what excellent playing, what an amazing interpretation of this piece, this Ulrich Böhm. I suppose if you’re going to be the organist in the church where Bach worked, you’d better know how to play that thing. Just a few things that I want to point our attention to. We’ve heard twice, and we will hear a third time when I finally play the ending. This sneaky chord, this ultra-deceptive cadence. These moments, you obviously think the music will go... No, Bach sa...
