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 E-flat 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.
