Intro to music theory courses are usually very surface level, try going deeper into music theory and then things will click, imho.
livingpianovideos on youtube, they do some of that. Mostly things about technique, though, which would also benefit you immensely. What in specific are you looking for? It would help immensely with those trying to help you. Cheers!EDIT: I don't know why I didn't think of this earlier- Music Theory for dummies. They have in-score examples all the time. Great read, and usually pretty cheap (I got mine for $10 new). In that book, they mention other good reads, as per usual with the Dummies' series.
I think this is key. I'll keep working on it. These videos seem helpful! (Things like this: "What is counterpoint?" are helpful to me in the context of what I'm working on right now)I guess it's hard for me to pinpoint what I'm looking for in general. I'm working on inventions at the moment and I found a great book that analyzes them and I'm just working along and trying to understand the concepts they talk about that way. I'll look into music theory for dummies and see. Thanks all!
