Triple Duo (1983) by Elliott Carter
for flute, clarinet, violin, cello, piano, and percussion

Triple Duo, for an ensemble of six musicians, is a work, as its name implies, that treats the group as three pairs of instruments: flute/clarinet, violin/cello, piano/percussion. Each of these pairs has its own repertory of ideas and moods. This free fantasy involves various contrasts, conflicts and reconciliations between the three duos. Triple Duo was composed during 1982 in Waccabuc, New York.
