Metametrics: Origins 2

As a performer – and I was a pretty good pianist in college, it’s the regret of my life that I didn’t keep it up – I never liked the feeling of complicated tuplets that couldn’t be expected to be played exactly right. I imagine you know what I mean: septuplet quarter-notes over a 4/4 measure, or an 11-tuplet with a couple of notes missing, and the composer says, “It doesn’t have to be exact, just make sure you end the phrase on the downbeat.” I never liked cheating, and I was so obsessed with polyrhythms that I didn’t want to fudge them, I wanted to feel them and feel secure playing them. Even with an ornamental quintuplet in Chopin, I worked to get it mathematically right. I had fallen in love with the three-against-four, two-bands-at-two-tempos section of the “Putnam’s Camp” movement of Three Places in New England, and at age 14 I said to the Universe, “Sir, it will be an honor to devote my life to replicating this effect.” So the fake polyrhythms, the little flurries that didn’t need to be accurate to achieve their goal, bothered me.

Judging from the music of my contemporaries, I wasn’t alone. The evolution of multitempo music in the wake of minimalism during the 1980s was an exploration of playable tempo relationships. When Conlon Nancarrow went this route, not relying on performers, he followed the arithmetical logic of numbers, going from tempo contrasts like 14:15:16 to 17:18:19:20 to 60:61. Those were impractical for the guys of my generation who wanted their bands to play multitempo music. Instead, they started out with simple relationships anyone could play, like 3-against-2 and 4-against-3, and then nested them. For example, take four drummers:

No. 1 plays a steady beat.

No. 2 plays a triplet against every two beats of 1.

No. 3 plays a triplet against every two beats of 2.

No. 4 plays a triplet against every two beats of 3.

This triply-nested 3:2 yields a pretty complex tempo resultant of 8:12:18:27, Drummer 4 playing 27 beats to every 8 by Drummer 1. This is exactly what Art Jarvinen does in one section of his Ghatam for sculptural percussion (1997), as you can hear here. He builds up the rhythm slowly, as a process, and doesn’t try to notate it, just gives instructions, because the notation would be needlessly complex.

This is also the same rhythm, though, that Ben Johnston used in the first variation of his “Amazing Grace” Quartet, No. 4 (1973). Going up one more 3:2, to 16:24:36:54:81, Ben did notate it, using different simultaneous meters to handle the overload. (You can hear that variation here, in the brand new recording by the Kepler Quartet.) Two variations later, Ben achieves (with great difficulty for the performers) a large-scale rhythm of 35:36, the same way one arrives at it in tuning pure pitch intervals: as the difference between a 9:5 and a 7:4 (or, rhythmically, 9 in the space of 5 and 7 in the space of 4). For Ben, as for Cowell in New Musical Resources, the methods of extending rhythm flowed by analogy from traditional ways of handling pitch, which was one of the core meanings of the word totalism in the first place.

In fact, Ben (who was my postgraduate composition teacher) could be taken as one of the leading and underacknowledged pre-totalist composers, perhaps even the most influential one. It was he, after all, who, in 1967, translated a 12-tone song in pure tuning into analogous rhythmic ratios, and those ratios into a rhythm-only piece of conceptual theater that was to be beaten on the outside of a piano with any available mallet-like objects. Titled Knocking Piece, the work was played all over the Midwest in the ‘70s, and was an obligatory virtuoso showpiece for young percussionists. It always had two tempos going at once, in ever-changing ratios determined by the 12-tone row the song had been based on:

The equal signs between measures indicate that the same pulse continues across the barline at that point. (No recording I know of available, unfortunately. If you know something about tuning, you can figure out the original pitches from these rhythms: taking the first as C, it continues G, E, B, D#, A#, F#…) Ben’s reputation never took off on the East Coast to nearly the same extent. But insofar as some of the totalists had been educated in the Midwest, Knocking Piece may well have been a seed that quietly (or rather, noisily) blossomed in the music of 1980s New York.

The piece that went furthest in exploring this kind of performable tempo layering, as far as I know, was Michael Gordon’s Four Kings Fight Five of 1988. Scored for three winds, three strings, percussion, electric guitar, and synthesizer, the work starts out with a melody that pits quarter-notes against dotted quarters in 6/4-slash-12/8, because the other rhythms (the four kings who fight against five) are going to be drawn from this concurrent contrast. The pounding opening, with much unison, is the part most relevant to the piece’s dedication, which is to Glenn Branca – of interest to those of you who may doubt whether the Branca/Chatham artrock of the time had any immediate connection to totalism. (Branca produced Gordon’s first record, as well.)

At 3:08 (three minutes, 8 seconds) into the recording of Four Kings Fight Five, the music pauses, and a rhythmic continuum starts to build up that will proceed through eleven different tempos, as many as seven of them at a time. The tempos are represented by the following note values, repetitively articulated:

quintuplet 16th-notes in the space of 6 (a dotted quarter)

triplet 8th-notes

dotted 16th-notes

8th-notes

triplet quarter-notes

dotted 8th-notes

quarter-notes

quarter-notes tied to 32nd notes*

dotted quarter-notes

half-notes

half-notes tied to 16th-notes

*(Gordon notates the quarter-notes tied to 32nd notes as dotted 8ths in a tuplet over the three 8ths of a dotted quarter beat, but it works out the same. Don’t worry about it.)

The eleven available pulses are given here with the ratios of their relative tempos and durations:

These ratios can be seen as analogous to pitch. If we take the quarter-note as C and the triplet quarter as G, we get the following “harmony” of tempos:

A – 60 tempo – quintuplet 16th-notes in the space of 6

G – 54-tempo – triplet 8th-notes

F – 48-tempo – dotted 16th-notes

C – 36-tempo – 8th-notes

G – 27 tempo – triplet quarter-notes

F – 24-tempo – dotted 8th-notes

C – 18 tempo – quarter-notes

Bb – 16-tempo – quarter-notes tied to 32nd notes

F – 12-tempo – dotted quarter-notes

C – 9-tempo – half-notes

Bb – 8-tempo – half-notes tied to 16th-notes

Note the self-inversional character of this harmony, except for the fastest A-tempo. At the work’s most complex point (long before the halfway point, at about 5:47), there are seven tempos going at once:

You can sort of see that everyone else is playing off either the quarter-note beat or the dotted-quarter beat, which are unified in the keyboard part. The viola and bass clarinet play triplets off the quarter-note beat. The violin, less obviously, is playing 2 beats to every 3 dotted-quarter beats. The oboist, poor dear, is having to play 4-against-3 to the dotted-quarter beat, or 16 even pulses over three measures; actually twice the tempo of the violin, but not lined up in rhythmic unison with it. Here six of the lines are cued to the dotted quarter beat and three to the quarter-note beat, but one assumes that elsewhere the ratio is four lines against five, as per the title.

From here on, the piece gradually floats into a more static continuum, which became typical of Michael’s music about this time. At 19:22 a viola starts up in free rhythm over the throbbing G major continuum underneath, and at 20:56 a snare drum rhythm in military time joins it, and the piece dies away. You can hear Four Kings Fight Five in its 23-minute entirety here; the rhythmic points I’ve been making are all illustrated within the first seven minutes.

Please don’t get too exercised over whether you “like” the piece or not. Frankly, I don’t find it, overall, one of Michael’s most compelling works, though I certainly love parts of it – I somewhat prefer Thou Shalt!/Thou Shalt Not!, Yo Shakespeare, Trance, and the Van Gogh Video Opera, among others. The question is not whether you “like” it, but whether you understand what it offered in terms of multitempo composition. In that respect it was not only remarkable for 1988, but offered possibilities that have still not been fully explored since.

What’s common to all three pieces, by Jarvinen, Johnston, and Gordon, is that the performers achieve a remarkable degree of rhythmic complexity – a true “harmony of rhythms” in Cowell’s sense – by selectively listening to some performers within the ensemble whose pulses they play off of, and having to ignore others. The ability to maintain a 4-against-3 rhythm over a steady-beat reference point, and the relative impossibility of securely maintaining a more difficult 27-against-16, is the same in rhythm as it is in pitch: a perfect fourth (4:3 pitch ratio) is easy to tune, a Pythagorean major sixth (27:16) extremely difficult. Gordon could still have gone a little farther than he did by factoring in more 5-against-4 rhythms, both as quintuplets and as quarter-notes tied to 16th-notes. I have sometimes succeeded in getting a class of students to clap 25-against-16 by conducting a quarter-note beat and having half clap quintuplet quarters while the other half clap quarter-notes tied to 16ths. Gordon goes only so far as a quintuplet over the dotted-quarter beat. I don’t know of a piece that went further in drawing so many competing rhythmic layers at the same time in a large, live-ensemble texture. It wouldn’t surprise me if Gordon’s Trance does, but I haven’t seen the score.
