taken from the introduction:
'....The Fanfare gives an opportunity for all players to move together in precise rhythm: the Canon gives scope for rhythmic independence but with musical material that all players can learn together.
The lowest part of the Fanfare and the optional two-part canon do not go above the break and the pieces are suitable for beginners to intermediate players.' Alan Bullard
