SONATA DUEGALE was composed especially for cellist Diane Roscetti in response to a conversation about the ranges of the Bass Trombone and the Cello which are similar, though the techniques and timbres are very different. The entire work consists of passages where the roles of the duet partners are traded or swapped. In each section the cello will have the melody and the trombone the support; then the trombone has the same or similar melody and the cello has the support; then they change again. There are deliberate technical challenges and special effects for both instruments planned throughout the piece. The first movement is in sonata-allegro form; the second is a march; the third, a theme and variations; and the fourth a rondo that becomes a samba before it is finished.
