Boomwhackers and Wak a Tubes are colourful tuned plastic tubes played by hitting them on something hard! They are produced in different lengths so they can produce different notes, and are usually provided in a pack of diatonically tuned notes. At Normans we stock both diatonic (white notes on the piano) and chromatic (black notes) Boomwhackers and Wak-A-Tubes. Put them together and you have the full chromatic range. Hugely popular with schools, groups and families. Great for musical fun, especially with younger players.
