Volume 1 (ED 22555) contains very easy to easy pieces with a range up to written c", with d" appearing as a short top note in just afew pieces. Simple and memorable rhythms, readily playable note sequences and patterns of articulation that can be mastered quickly and easily make this book ideal for beginners.
Volume 2 contains easy to intermediate pieces with a range no higher than f". Besides extending rhythmic scope and requiring a little more in terms of phrasing and articulation, these pieces will encourage further exploration of musical contrasts.
Volume 3 is of medium difficulty and intended for players with a well-developed embouchure who can play notes up to written g", though this note only appears as a short top note. Flexible articulation and legato playing with a well-developed dynamic range are required for pieces that are longer than those in the preceding volumes.
