This Interaction should have a relentless energy. The player is invited to explore and extend dynamic contrasts and articulation. The play of major and minor thirds generated from the Slonimsky pattern 29 is placed into a template ‘(= x x = x = x x = x = x = x x = x x x x x) which is found in the first two and last two staves. Between these staves the template evolves through a series of shuffling operations, the first outcome of the shuffle forming the basis for the next shuffling, and so on.
The Slonimsky pattern used here begins to demonstrate the transition taking place as the Interactions progress. As the second pitch rises by a semitone, the fourth pitch falls by a semitone.
