Gabriel Koeppen is one of few cello teachers who compose easily playable cello literature in pop and jazz styles. The three blues pieces for solo cello require the knowledge of the 1st to 4th positions, addressing the great variety of the blues. In the slowly swinging 'Groovy Blues', the cellist accompanies him-/herself with left-hand pizzicatos. 'Blues con variazioni' is a mixture of styles - consisting of rock-like, pounding blues shuffle, guitaristic bottleneck effects, bebop phrases and funk rhythms. The third piece 'Busy Blues' is an intense and hectic piece. A valuable addition to the repertoire for tuition, concert and the competition 'Jugend musiziert'.
