Clarke wrote Cousins, a cornet and trombone duet with band accompaniment, for himself as the cornet soloist and Leo Zimmerman as the trombone soloist. This arrangement of Cousins is a piano reduction. Also included is a solo part with another cornet (or flugel horn) to play the trombone part. This offers the opportunity to perform Cousins with a pianist in a variety of settings such as school master classes, recitals and outdoor park concerts.
