Q: Same as a majority of music (at least western music) being in 4/4 time.. is there something special about 4/4 that has made it become "standard"?
A: in time, 2s are very powerful. that's because 2 is a low number, and almost anything can work in 2s. breathing (in, out) walking (left right). the next number is 3, which is also low, and very simple, and that is a prominent number in musical rhythms as well. 4 is just 2 2s. so when something is in 4, it's just 2s. 2 groups of 2. and then 2 groups of 2 groups of 2 (2 bars.) and then 2 groups of 2 groups of 2 groups of 2 (4 bars.) that's why music works so well in 4, 8, and 16 bar sections. you're just hearing 2s in 2s in 2s etc
