3 Bb, Eb Alto, Bb Bass, & Eb Contra-Alto Clarinets with opt. Castanets. Straight from the second act of Georges Bizet's most famous opera comes this animated theme adapted by Lloyd Conley. Special recommendations here include using the optional castanets part for stylistic authenticity whenever possible and assigning two players to each Bb part to cover the abundant divisi passages.
