Where does a music composition come from?
If one answers with a simple and logical “inspiration”, where is it stored in its uninspiring state?
Where does an idea come from, outside of the realm of necessities?
Where is the revelation coming from that brings orange hues together?

I do not know, generally.
Could it be that an idea only arises because one sees a logic which has yet to be embodied? Is it merely the call of a concrete notion that exists but is asking to be completed by becoming physical?
