What you are referring to, Manu, was first expounded upon by Pythagoras through the explanations of the concepts generally of Sacred Geometry and the Music of the Spheres, and was delved into specifically with the Tetractys. All these things require intense study, but it is most rewarding as they show the point where physical sciences and metaphysical sciences intersect.

Should I quote the passage about the Divine symphony or do we all know it well enough by now ?
