The Boomwhackers BW-PG Set is pentatonic set of color coded percussion tubes and contains six tubes with the notes C, D, E, G, A, and C'. Thanks to the use of a pentatonic scale, these boomwhackers are ideal for first musical steps, because they always sound harmonious, no matter in which order the tubes are played. In addition, there is the visual connection between tube color and note value, which helps with teaching and learning. Also suitable as an extension of an existing Boomwhacker assortment.
