NEW - YAMAHA CLASSIC PENDULUM METRONOME BLACK Spring-powered Pendulum Timing The classic pendulum design uses a sliding brass weight to adjust the tempo - the higher up the weight, the slower the speed, and vice-versa. The pendulum is powered by a mechanical spring that's tightened with a hand-turned key, so there's never any need for batteries or electricity. Easy-to-read Tempo MarkingsA series of commonly used musical tempos are clearly marked on the face of the metronome, making it easy to quickly slide the weight the correct position for the speed you need. Downbeat Bell In addition to the basic tempo, a downbeat bell can be set to ring at every 2nd, 3rd, 4th or 6th beat. Lightweight and Durable Plastic Body The plastic body is lightweight, durable and easy to clean, and the matte finish helps hide fingerprints. #MP-90BK2 Powered by SixBit's eCommerce Solution
