Interesting YT channel on (mostly) classical theory

It's basically a series of short (3-5 mins) videos with some amusing timelapses that explain the theory from basics to some way out there stuff.

I haven't yet watched most of it, but it's definitely a good refresher, though this style may or may not work for you if you never even tried to study the theory before.
Nice find, though it looks like it is aimed at understanding sheet-music, but it is a huge collection of theory-videos!
I will move this to Tutorials
Although a first few vids are about sheet music he doesn't focus on it, he just explains some basics and then some more unusual symbols he occasionally uses as he goes along.

He also actually plays most his examples and uses Roman chords too when appropriate, so even if you aren't very good at reading sheet music, (like me) you can follow.
I agree. This is really a nice find.
I'll check them out, as soon as I have some time. :)
