Eli5 – Why does music come in bars of four instead of 5/10?

1.62K views

Recently I’ve been attending a lot of gym classes and the counts are always 4, 8, 16 etc. It made me wonder why music is set out this way and not in 5’s and 10’s like I would expect. Or am I missing something obvious?

i don’t know for real but i suspect biology. heart beats are closely related to music beats and tend to have 2 main parts to them. walking is the other one, left, right, left, right.

so the base is two, two sets of two seems to be about the base.

but other things work too, 3 count is very common with 3/4 6/8 being very common. 5/4 does exist, but it’s less common.
