Cuarto de ESO: groove, polirritmia y una coreografía entera

In 4th year the body is already a drum kit. Here you play the backbeat of "Uptown Funk", cross two rhythms at once, build a four-voice piece and end with a full choreography on a current song. And, at the end, one of your own.

Before you start

The basics are in The body as an instrument. The 3rd-year material, canon and triple time, is taken as read. And it helps to have read Why does everyone clap in the same place?, because this whole chapter is about the hit on two and four.

The groove: the 4th-year songs on the body

A groove is a repeating pattern that makes the body move on its own. The theory is in Why doesn't a one-chord song bore you?. Here you play it.

  • We Will Rock You, for real this time: a long tutorial and its play-along, by the same author, in Spanish.

Polyrhythm: two rhythms at once

A polyrhythm is when one part of the body goes in three and another in two, or four against three, at the same time. It is the hardest thing in the book and the most striking when it works. Salvo Russo introduces it slowly; then the flamenco bulería, a twelve-beat polyrhythm.

And the rumba clave, the one Cuban hand-clappers keep, as a coordination exercise.

Keith Terry, the musician who coined the term "body music" in the seventies, works with "rhythm blocks": chunks of three, four and five hits combined like pieces. Explained in Spanish.

Four voices

With the class split into four groups, each with a pattern, you build a whole piece with no instruments. Mr. Noé has a four-voice game and a challenge on "Wellerman".

And the classic body percussion piece: "Clapping Music" (1972) by Steve Reich. Two people clap the same pattern, and one of them moves one eighth note ahead every eight bars until they meet again. Reich wrote it after watching flamenco hand-clappers in Brussels. Here, a version for five.

Songs of now

Three choreographies on songs from the last few years, to copy by watching.

The full choreography

The year's project. Two options, both with a two-part tutorial and the full piece at the end.

And, as a model of how far this can go: Filz playing Bach's Badinerie with nothing but his body.

One of your own

The last step in the book is composing. In groups of four or five: pick a song from your phone, find its backbeat, set one pattern per section (verse, chorus, bridge) and record it. The curriculum calls it "creating artistic and musical proposals using the body". We call it the end-of-year concert.

Classroom activities

  • Backbeat on anything. A student plays a song from their phone; the class finds the two and the four in under a bar. Change song every thirty seconds.
  • Three against two. Feet in two, claps in three, until both hold. Then the other way round.
  • Four groups, one conductor. The conductor signals which group comes in and which goes quiet. The piece is different every time.
  • Phasing. Two rows do the "Clapping Music" pattern; the second row moves one eighth note ahead when the teacher signals.
  • Project. One term for "Therefore I Am" or "Dance Monkey", and another for the original composition.

Key vocabulary

  • Groove: a repeated rhythmic pattern that makes the body move on its own.
  • Backbeat: the hit on beats 2 and 4 of the bar.
  • Polyrhythm: two different rhythms at once, such as three against two.
  • Rhythm block: a group of three, four or five hits combined with others.
  • Phasing: one voice gradually moves ahead of an identical one.
  • Bulerías compás: the twelve-beat flamenco cycle, with accents on 3, 6, 8, 10 and 12.
