The octave caps are designed to sit on the end of your boomwhackers to tune your boomwhackers an octave higher!
Boomwhackers sold separately.
Boomwhackers are colour-coded plastic tubes cut to different, precise lengths to create the C Major diatonic scale. This is a set of 8 notes from C to C.
By knocking or banging, pitched sounds are produced. The children will learn disciplined collaboration, coupled with huge amounts of fun!
