I think Pythagoras had it right 500 BC when the subject matter of his school was as follows 1. pure mathematics number unto number or linear 2. music theory numbers in time or 2D. 3 Geometry or numbers in space 3D. 4 Numbers in time space or geometry in temporal motion or astronomy which is 4d. Check out book 5 of Euclids The Elements music is and always will be a mathematical science check out Hans Kayser Text Book of Harmonics or google the tetraharp by barbera hero
