This collection of 16 well-known works from the classical repertoire for trombone quartet are presented here for grade 3-5 groups. This collection was specifically arranged to allow for flexible low brass instrumentation. The 4th part may be played on bass trombone or tuba, and the upper three trombone parts can easily be exchanged for baritones (B.C.) to the extent that these could be played solely by a baritone-tuba quartet.
