What an ingenious little percussion instrument this one is! Resonant pine note bars are mounted on a round base. With the included rubbing or striking stick, you whirl it around the inside of the xylophone for unique, melodic sounds. Twirl the stick one way for ascending sounds, the other way for descending sounds. You can also lightly tap the outside for simple, earthy sounding melodies. Available in small, medium, and large sizes. Great fun to play for all ages.
