With the exception of Willem Frederik Bon's prelude for orchestra (1972), most later works have been for a restricted number of instruments. They include Hendrik de Regt's "Circe" (Op. 44, 1975) for clarinet, violin and piano; Christian Manen's "Les Enchantements De Circe" (Op. 96, 1975) for bassoon and piano; and Jacques Lenot's "Cir(c)é" (1986) for oboe d'amore. The German experimental musician Dieter Schnebel's "Circe" (1988) is a work for harp, the various sections of which are titled "Signale" (signals), "Säuseln" (whispers), "Verlockungen" (enticements), "Pein" (pain), "Schläge" (strokes) and "Umgarnen" (snare), which give some idea of their programmatic intent.
