Triptych 6'22

Triptych is a compositional exploration of the timbral evolution of a single percussive sound. Influenced by Schoenbergís Klangfarbenmelodie, this piece juxtaposes various extracts from throughout the soundís evolution in an attempt to illuminate the rich timbral variation of the sound, from instant to instant. The work is divided into three sections, each of which provides a differing temporal perspective on the sound: from micro level variation, where successive individual instances of the sound are held in suspension and gradually layered on top of one another; to a granular reconstruction of the soundís aggregated timbre from non-successive samples of varying size; to a temporal compression of the sound so it appears as pitch with its own unique timbre.
