You can express music way better than 4/4, 3/4 etc. Using the same formula.
Music is made like a fractal: a ratio inside a ratio inside a ratio etc, and it goes all the way in to the waveform level.
So here's how this one song I played goes:
(((7/4)/7)/7)/4
I think. Or should I get rid of those slashes? Do the brackets mean there's a fraction in here?
