ChromaNotes 8 note Resonator Bells share the same color template as the Boomwhackers tuned percussion tubes. Line bells up to play solo, or separate them for use with small groups. Each bell is attached to a unique tube-shaped base for great resonance, sustain and a deep, rich sound. The set is flexible enough to be used in classrooms as an educational tool, or at home for the sheer fun of making music!! Comes in a convenient, durable carrying case (16" X 12" X 3") and 4 pairs of mallets for multiple players. Age 3+.
