The math<->music link exists but you don't need a ton of math to just do some music.
Western music theory does use numbers to organize itself, and if you really want to number up, look into classical Indian music and how it treats subdivisions.
I didn't study math past the age of fifteen (which is when I started music, coincidentally), but have never encountered a musical situation where math was the stumbling block.
