Derivé 1.fl, cl(A), vib, pno, vln, vc (1984).
Ensemble intercontemporain.
Director. Pierre Boulez.
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.
