What do you consider to be some examples of a music theory breaking or being evaded by music?
all the time. every moment of every piece of music. notes change. Let's say we're on a note, minding our own business..... music theory at this moment is telling us this is the 'correct note'. But then we switch notes, so why the heck would we switch away from the right note? Ok, well, maybe right now you're thinking, "but music theory is not just 1 right note, it's a series of instructions for what is the right series of notes." in that case i would have to point out that no such instructions exist
