Dérive I (1984) – Pierre Boulez
Dedictaion: pour William Glock
Flute, Clarinet, Violin, Cello, Vibraphone, Piano
Dérive translates roughly as “derivative”; the piece is derived from the two compositions Répons (1981) and Messagesquisse (1976/77). The “derivative” is also a sequence of variations “on the name Sacher”. Six chords build a circular rotation, which mimic the structure of the piece, but also soften it.
