I've noticed several forum members really working hard on understanding theory and applying it to music that they're working on. Sometimes it can get overwhelming!

I do have a major problem (no pun intended) with music theory. It's not so much the theory itself (if you're a "math" type of person, it's actually very straightforward). It's what you do with the theory, or let it do to you by imposing limitations (for example, some people don't want to leave the major scale, no matter what happens!)

From my perspective, it all comes down to this: Theory is about music, but music is NOT about theory.

Theory is a tool, and quite possibly the quickest path towards becoming an accomplished musician. It should not limit your options; it should open new doors. And you can't forget to trust your ears!
