Below are 8 sheets, which should enable a group using the diatonic set of boomwhackers (8 note set, C to C), to play twinkle twinkle little star. The scores/sheets use numbers, so you don’t need any knowledge of conventional notation. Each player simply plays the yellow numbers and keeps silent for the black numbers. If the players of all eight notes do that correctly, starting and finishing together and maintaining the same speed throughout, then all the parts should fit together, like a musical jigsaw, to produce twinkle twinkle twinkle.
