The piece, “Étude aux fluxions”, developed as an exercise in the simple melding and manipulation of sonorities of wood and metal percussion instruments (marimba, vibraphone, bells) with sustained chords of electronic tones. Harmonic progressions of gradually transposing pitch constructs, events of repeating rhythms and oscillating motifs, and the appearances of broad melodic movement in the lower spectrum make up the componants of the underlying language of the piece.
