A metronome, from ancient Greek μέτρον (métron, "measure") and νέμω (némo, "I manage", "I lead"), 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 practise playing to a regular pulse. Many metronomes are now digitized, either in the form of electronic chips instead of mechanics in metronomes, or entirely digital metronomes stored in the cloud or a computer and accessed via a web browser or metronome app.
