Includes sections on chordal exercises, exercises in all keys, broken chords, dominant 7th chords, diminished 7th chords and chromatic scales. For bass trombonists, most exercises range well into the trigger and pedal registers. Appropriate for the intermediate bass player wishing to develop solid mastery of the trigger/pedal registers. The nature of the music helps develop eveness and connectedness to the middle and upper ranges. For tuba players, the upper register is the challenge, and the composer has given ossia passages where appropriate. 63 pages. --cdp
