A metronome produces a steady click at a chosen tempo, measured in beats per minute (BPM). Musicians use it to keep time while practising scales, songs and rhythms.
Set the tempo by dragging the slider, or tap in your own rhythm with tap tempo. Choose how many beats are in a bar, and the first beat of each bar clicks with a higher accent so you can hear the downbeat.
The click uses the Web Audio API, which schedules each beat to the millisecond — far more precise than a simple JavaScript timer.
Common tempos: 60 (slow), 90–120 (moderate), 140–200 (fast). Start slow, master the part, then increase the tempo.
