That is also why most music is written around intervals of 60 PBM. If you hand a musician their instrument of choice and just have them noodle around they almost always play at some multiple of 60 BPM (90, 120, 180, 240). I can play scales all day long with 16th notes at 60, 75, 90 and 120 BPM, but some odd interval close to those numbers like 72 or 87 and I will be lucky to get a run of 10 in a row. My brother tends to hang around 145 which has always puzzled me, then I found out his resting heart rate is 72 BPM. It is like the body uses itself as a metronome. Pretty cool actually and it also explains why bands tend to play faster live as the set goes on.
