Bass Clarinet,Instrumental Duet - Level 3 - Interactive Download SKU: A0.1368015 Composed by Tyler James Cook (ASCAP). This edition: Interactive Download. Classical. 3 pages. Duration 148. Tyler James Cook #3CEiZFup8qEN0udIhC0SU3. Published by Tyler James Cook (A0.1368015). Key: Ab major.Tomato Roll is a duet for clarinet and bass clarinet in 5/8 time. It starts with a doleful G minor (concert F minor) theme, before morphing into a more optimistic (and tasty) Bb major (concert Ab major) section with a Baroque feel. Both parts get plenty of flowing, moving lines, with both musicians playing off one another in a juicy clockwork of motion and harmony.
