BPM: Rover

Give tempo and time signature

The speed at which music is played/performed is expressed as beats-per-minute or BPM. The more BPM, the faster the music goes. Most music uses the same BPM range as the human heartbeat: 60-140 bpm.
A base of 16 means that the bar is divided in 16 parts of length 1/16. The most common bases are 4, 8, 16 or 32. Use base 12 or 24 if you also want calculations for triplets.
This is also used in "Quantising": the process of snapping notes to the nearest beat subdivision.
