This neat little gadget is the perfect accompaniment to any strummer - guitar, uke, whatever it is you play, play it with the Rhythm Ring and add a bit of extra sparkle, a maraca-type shaker rhythm, in perfect time with your strumming hand. Alternatively, it is great for cajon or bongo players, adding a crisp rhythm to your play. It is well made, tough polycarbonate with composite steel balls inside. And it isn't expensive so well worth experimenting with.
