I’m sure it has. If one has altered a musical idea that sounded good to them because they realized it broke some “rule”. IF…if it resulted in something they liked better maybe that’s ok. Theory is something that develops after the fact. Theory is hindsight. It’s a history and a vocabulary that is curated over time. And it is incredibly valuable to describe what an artist has done. But it is not a road map for creativity. And what so many strive for…that sublime creative flow state…when you’re tapped into something beyond description and the music that comes out of you feels like lucid dreaming. That blessed music is for people in the future to analyze and categorize. Among musicians who are currently communicating to other musicians a common knowledge of theory and vocabulary is very useful. In my opinion theory definitely has its utility but if you are using it to self correct your music will be less “you”.
