It might be unobjectionable to say that thinking has musical form, up to a certain point. You can see that it involves a certain dissonance which is resolved, perhaps by a series of logical cadences or perhaps all at once, in the thought which you have been trying to reach.
"I am thinking my way towards something." Here you feel the thought as what would satisfy, though you can say nothing else about it yet.
But what about the thought itself? Aren't my thoughts punctiform, static, and complete in themselves, once I have arrived at them? At least, those thoughts which I am inclined to call "thoughts about facts." There do seem to be two kinds of thoughts: 1) those having to do with "what is the case," (facts) and 2) those having to do with the directedness/intentionality of the one thinking (shall we say, values). The latter would seem to have something musical about them, but the former, well, not so much: "prosaic" seems more the word.
Try and pick up one of those "punctiform, static, and complete in itself" thoughts, and see if it serves your purpose.
