If you have a large percussion section, Credo might be a perfect piece for your young band. It is very carefully scored and cross-cued, so that almost any size band can perform it. Composed in sonatina form, it is highly energetic and tuneful, and the bass instruments have lots of fun, easy things to play. Credo is very safely scored, with Piccolo, 2nd Oboe, 2nd Bassoon, Contra-Alto Clarinet, 3rd Trombone and Double Bass parts optional. Ranges are very reasonable; the only sixteenth notes in the piece are in the snare drum.
