This enjoyable collection of pieces, arranged as duets for pupil and teacher, will provide the elementary player with an under­standing of the basic principles of their instrument.

Taking as their starting point the notes of the harmonic series, the duets become progres­sively more challenging without making unreasonable demands in terms of range and technique, allowing the pupil to gain security in the middle register.

The teacher's supportive accom­panying parts will inspire confidence and give the student a valuable intro­duction to ensemble playing.
