Clarke wrote Cousins, a Cornet and Trombone Duet with Band Accompaniment in 1904 for himself as the Cornet Soloist and Leo Zimmerman as the Trombone Soloist.
To create a clean new edition, dynamics and articulations were made more consistent in the parts. Other items were changed to reflect the bands of today including F Horn parts rather than Eb and the percussion parts have been reorganized. This is the first time this work has been available with a full conductor score rather than a piano reduction.
