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’ve been waiting for metricized music notation for many years. All that fractional stuff is obsolete. /s

It depends on the type of music. Most pop songs are 4/4 but listen to some waltz and its 3/4. That famous jazz song Take five by Dave Brubeck is 5/4 while many other jazz songs are 4/4. Like someone else said your gym most likely has pop music playing which is 4/4 therefore they used the beat to count.

A lot of music is not in 4/4, but most popular music is. 6/8 is pretty popular too.

Here’s a song that is not in 4/4. Try and follow the rhythms in it. I warn you that this is not music for the “least common denominator” sort of crowd, though:

People generally find a more straightforward cadence in music to be more catchy and easier to follow.

Your heart beat establishes rhythm. Very little in nature aside from your digits comes in 5s or 10s.
