Oh, it's a real fact? Shows you how little I know.
So, what do you do with that fact?
Maybe I can get back to trying to learn music theory if I knew what to do with it.
It's been years (many years) since I learned music theory; and I don't work in any kind of music related field. So whatever I still remember, should it be labeled memorization or just realizing something that makes sense? I mean, I kind of know enough English grammar to type up this post; would that count as memorizing grammar rules?
I'm sure over the years, I've forgotten most of the music theory; but there are still a lot that we use everyday when we play music. I don't find it like memorizing that (0232) is a G chord because this I actually forget (and sometimes think it'll give me a D until I hear it). However, if I really can't hear this chord and really, really can't remember whether it is a G or D, I can work it out with music theory (which I know but can't seem to forget as easily so... would it be memorizing or just some kind of realization kind of thing?)
I think if you know more theory than you can use, then it is not that useful. However, I think the topics posted in this thread are pretty basic and are things that you'd use everyday. So, I don't think you can forget it even if you try to.
