SATB/AATB. The Boogie Woogie Bari Boy is a groovy little sax quartet that features, you guessed it, the baritone sax. It has a medium difficulty but the baritone part requires a lot of air! It is swinging and unpretentious. For two altos, tenor and baritone saxophone with an auxiliary soprano part that can be used as an alternate to the 1st alto.
