A device that produces a click or sound at a regular interval, set in BPM

A "metronome" is a device used for controlling musical rhythm, often employed to maintain a steady tempo and beat. It produces regular auditory or visual signals to assist musicians in keeping a consistent speed and rhythm during performance or practice.

The metronome is a common tool used by musicians and music students to ensure a stable rhythm and tempo while playing. It typically takes the form of a small mechanical or electronic device with an adjustable tempo control, allowing musicians to set the desired beats per minute (BPM).

During use, the musician sets the metronome to the desired tempo, represented in beats per minute. The metronome then emits a sound, such as a regular "tick-tock" or other auditory signal, or provides a visual signal such as a flashing light or moving pointer, following the specified tempo. This enables the musician to synchronize their playing with the metronome's indications, thereby maintaining a consistent rhythm and tempo.

The metronome serves as a valuable tool for establishing a sense of rhythm, especially during practice and rehearsal. It aids musicians in adapting to different music tempos and rhythms, and is particularly useful for tackling complex pieces, coordinating ensemble performances, and ensuring the overall coherence of musical interpretations.
