The pieces were originally designed with Trumpet, Clarinet, Alto Saxophone and Baritone horn in mind, and some had several parts. However, this music has been rearranged for all Brass and Woodwind in Bb (Trumpet, Clarinet, Bb lower brass), Bass Clef Brass, French Horn, Eb Horn, Alto Saxophone and Flute. It has been written in such a way that if your class, ensemble or lesson only has one of, or a selection of these instruments, the pieces will still work. The music is not designed for complete beginners, but it can be used once students have learnt the first five notes of the concert Bb major scale.
