Flocking (2015), for piccolo, flute, clarinet, soprano saxophone, alto saxophone, horn, flugelhorn, (2) trombones, tuba, percussion, and (4) voices.
Flocking was written for the Orkest de Ereprijs on the occasion of the 21st Young Composer’s Meeting in Apeldoorn, Netherlands. The piece was algorithmically generated in the programming language Supercollider. Using the first 16 pitches of the harmonic series, rhythmic relationships in the piece are based proportionally on the frequencies of the harmonics (a la James Tenney’s Spectral Cannon (for Conlon Nancarrow)). The tempo, however, gradually slows down throughout. As these rhythms are quantized to the nearest eighth note, what begins as a quasi-hocketting exercise transitions into a more and more accurate polyrhythmic overlay. Groups of pitches are introduced in staggered fashion, eventually appearing in toto at the piece’s climax.
