Music names the same quantity differently: tempo, measured in beats per minute (BPM).
A tempo of 120 BPM means one beat every 0.5 seconds — a period of half a second, a frequency of 2 Hz. A slow adagio at 60 BPM is a 1-second period, exactly the frequency of a resting heartbeat.
Tempo is simply frequency wearing a musician's name.
