OP here, posting more stuff.
Music theory. Is it really useful? Or will it kill/hurt your creativity?
I found a good answer to this question on 4chan:>Having a vocabulary large enough to know when to choose the right word is always a good thing.>Using your large vocabulary to make hyper-verbose word salad is a bad thing.>A lot of great songwriters use their understanding of music theory to communicate simple and effective ideas. Some songwriters use that same knowledge to make musical word salad. The music theory knowledge isn't what makes them good or bad.
Here's a video that goes more in detail video about these things: https://youtu.be/02nBRDcUGNU
It explains more advantages/disadvantages of learning theory or not learning it. If you have doubts on wether you need music theory I recommend watching it
