Girl please help theory homework is kicking my ass. Do you have like sites or people that explain music theory comprehensively....
I used Teoria a lot when I was in college. It has both tutorial pages on music theory concepts and practice exercises to help you apply them practically. I mostly used the latter since my theory professors would assign us ear training exercises every few weeks, but the tutorials delve into a lot of the trickier theory topics like secondary dominance or the many, many types of non-chord tones, so they're pretty useful. I'd recommend playing around with both because getting to read about a topic and see how it functions out in the Real World will help you retain things better. The information pages aren't the most detailed you'll find, but it's a good first start.
musictheory.net is also a good one. It's a bit more in depth than Teoria and goes into more niche territory, with lessons on topics like odd meter and cadences. Like Teoria, it has practice exercises as well.
Alternatively, if you learn better with a video format, there are quite a few YouTube channels I like that cover music theory concepts in a less conventional, but easily digestible way. They won't feel like a traditional music theory lesson, but if you already have the basics down they're a great way to learn and have a little fun at the same time.
David Bennett is one of them—his videos use a lot of examples from popular songs so you can really get a feel for how a lot of these techniques are relevant to the music we hear in our everyday lives, which is super cool!
8-Bit Music Theory is similar, but for video game music instead.
I've also been a long-time Adam Neely fan, but quick disclaimer that not only can he get pretty niche, but his background is in jazz, not classical, so the terminology/chord naming techniques he uses won't always be the same as what you'd learn in your standard music theory class, and not all the topics he covers will necessarily be relevant (or have even existed to begin with) in a classical context. Still very entertaining though.
Idk what concepts you wanted help with specifically but these cover a pretty broad range I'd say. Theory homework sucks (even if music theory itself rules) so I hope these help a little!
