This is the reduction for clarinet and piano of Copland's famous Concerto for Clarinet and String Orchestra. Copland is known as an American composer who used American folk melodies and strains in his work. This piece starts out at a slower tempo for more expressiveness, and builds throughout.
This is an ambitious work; it's playable by an advanced student and is a long, rich piece. Copland's mastery of melody and tone are evident.
