In addition to many performance pieces for cello, Kummer composed numerous studies and easy pieces such as
'12 Duets for 2 Violoncellos' Op. 105. They are one-movement pieces
which demand cantabile and concertante playing at a moderate level of
difficulty and are the ideal introduction to chamber music playing.
22 original cello pieces designed to inspire and encourage duettists, especially teacher/student collaborations. Duets progress from beginner to advanced levels. The two CDs include full performance tracks and practice tracks for each piece.
