The coolest—and most portable—instrument ever! Play it with guitar, ukulele, djembe, cajon, bongos, congas, or any other acoustic instrument . An exciting addition to music making in any setting—in the drum circle, around the campfire, in the classroom, in choir or band, in movement and dance routines—it helps you keep the beat and adds rhythmic texture to your strumming, singing, dancing, and playing. The Rhythm Ring is 1" diam. and 1½" long, made of durable polycarbonate, with an elastic strap that fits comfortably and securely around your finger (very small hands can use 2 fingers in the strap).
