WALTZ is designed to be performed by beginning bands and is ideal for a first or second performance.
The piece can be performed by full band or any combination of first and second parts plus a bass part. The trombone parts are optional and can be used with full instrumentation or dropped if you have weak trombone players. Have your trombones play the baritone part as a bass substitute. In the low brass and low woodwind parts there are a number of half notes followed by a quarter rest. Be certain these notes get a full value with a release as the third count begins.
In addition to full band performance there are many combinations which could be created and performed. A brass quintet of 1st trumpet, 2nd Trumpet, trombone 1, trombone 2, and baritone. A clarinet trio of 1st clarinet, 2nd clarinet and bass clarinet. Try two flutes and bass clarinet or baritone saxophone. Whatever combination you have available with two soprano instruments and one lower instrument will successfully perform this piece.
This selection can combined with Gavotte by the same composer for a two movement presentation.
