In your opinion, is it possible to learn classical music theory without being a musician? Also, is it something that can be learned by reading and listening, or does it require a teacher to be present?
I think that the doctrine "do, and understand" applies particularly well to classical music theory and composition, though I'm very biased in that regard. My post above mostly concerns the "theory of harmony", and my recommended way of learning that is to grab a textbook on the subject (one with exercises) and do the composition exercises. No need to play any instrument, as a geek you can use any software that features a good pianoroll. And here's the most opinionated part: teacher useful but not strictly necessary.
As someone who studied music but never got the commitment and discipline to play it well, I can tell you that learning music theory can be easier than playing it - at least for people like me.
This is strange because I can paint and sculpt very well, but playing is such a struggle for me... I really envy people that can play or sing naturally.
