A valuable resource of much needed practice material for Bass Trombonists in the orchestral gamut. Careful practice of these studies will help Trombone players cope with the problems present in the orchestral parts. Kauko Kahila's studies improve technique and confidence and help make the step-up to more complex pieces with special attention to the low registers and changing meters. This volume also includes an extract from Karl Pilss' 1974 Concerto for Bass Trombone and Piano.
