Rhythm Band Sound Tube

Twirl it over your head and explore the science of sound! This 38" Whirly Sound Tube changes pitch based on how fast you spin it—the faster you twirl, the higher the pitch. It's a fun, hands-on way to introduce the physics of music. You can also use it to develop pitch-matching skills by singing into one end and listening through the other. Produces an ‘F’ pitch at full speed.
