Cardew Choir Version
Performer Chart

1. Long Sound
Single pitches, held for a long time (full breaths, full bows, etc.) Timbral evolution definitely allowed.
5. Intervallic Line Formings
Melodic lines made up of large intervals.
9. Legato Formings
Melodic lines with legato articulation.
2. Accented Long Sound
Long sounds, as above, but with an accented, assertive attack.
6. Multiphonics
If your instrument doesn't really do multiphonics, any other sort of skronky noises will do.
10. Diatonic Formings
Melodic lines made up of notes chosen from a scale (of your choice.)
3. Trills
Quickly alternate two pitches, not necessarily adjacent, not necessarily regular rhythm.
7. Short Attacks
Isolated sounds with short attacks, like the diagram.
11. Gradient Formings
One or more musical elements -- volume, tempo, pitch, timbre -- gradually changes.
4. Staccato Line Formings
Melodic lines with staccato articulation. (Not a single pitch, despite the diagram!)
8. Angular Attacks
(Like the diagram?)
12. Sub-identity Formings
Digression -- a snatch of a familiar tune develops as a submotif out of a diatonic forming, ends and then yields to the latter; or a section of trills set within a piece primarily comprising long tones, etc.
