Wak-a-Tubes are brightly coloured percussion instruments made from different lengths of plastic tubing. They’re fun and easy for musicians of all ages to play – simply whack them against a hard surface, hit them against each other, or lay them out on a flat surface and strike them with beaters.Playing Wak-a-Tubes in a group is a great way to learn about teamwork and ensemble musicianship while having lots of fun. Unsurprisingly, this has made them very popular with schools.As a general rule, the bigger the tube, the lower its pitch. It can be fun to experiment with dynamics and timbre by varying the material the tubes are hit against, and the velocity with which they are struck. And don’t worry – they’re virtually indestructible!Tubes included are: C# (Db) 41, D# (Eb) 43, F# (Gb) 46, G# (Ab) 48, and A# (Bb) 50.
