Four Pieces op.40    Ralph Sauer has beautifully arranged four movements from Four Pieces Opus. 40 for Trombone and Piano:    1. Chanson Triste  2. Valse  3. Rêverie interrompue  4. Danse russe    These four movements, totaling fourteen minutes offer the artist a great deal of musical contrasts, ranging from lyrical, dramatic, dance-like, etc.    An excellent collection of the Russian masters music for the Trombone.
