ABC’s Trilobite Triacle was composed for Orkest De Ereprijs as part of the Young Composer’s Meeting composition contest 2012, and received the first prize.

The piece is built on a numerical exercise in threes. All structural and harmonic material derives from the numbers 1, 2 and 3, and letters A, B and C—worked out through permutation processes and 3×3 pitch grids. This generated melodic chord strands that wind through the ensemble like one big snake. The three sopranos articulate the tripartite form: first three chords ending in A-major, then two chords on B-major, ending on a single, blazing C-major.
