Rtm: Metronome

A metronome is a device that produces a steady beat, helping a musician play rhythmically. Tempo is measured in BPM (beats per minute). A tempo mark of 60 BPM equals one beat per second, while a tempo mark of 120 BPM equals two beats per second.

A metronome is typically used as a practice tool to help maintain a steady tempo when learning complex passages. You can also use it in live performances and recording studios to maintain the correct tempo while playing.
