A metronome is any device that produces regular, metrical ticks (beats, clicks) ? settable in beats per minute. These ticks represent a fixed, regular aural pulse.

The metronome is used by musicians to help keep a steady tempo as they play, or to work on issues of irregular timing, or to help internalize a clear sense of timing and tempo. The metronome is also often used by composers as a standard tempo reference, to indicate the intended tempo for the piece.
