Trio Sonata for 2 Clarinets and Bass Clarinet by John Harbison. Associated Music Publishers, 1995, SS, includes parts and score. In four movements, all fast. The first and second movements have some mixed meter but it is all of the easier variety without fractional beats. Early college level with a duration of 5 minutes. There are editions of the piece for strings, double-reeds, clarinets, saxophones and keyboards. The composer suggests the performers try mixed configurations of instruments. (C1931)
