A metronome, from ancient Greek μέτρον (métron, "measure")[1] and νομός (nomós, "custom", "melody")[2][3] is a device that produces an audible click or other sound at a regular interval that can be set by the user, typically in beats per minute (BPM). Metronomes may include synchronized visual motion. Musicians use the device to practice playing to a regular pulse.
