This question already has an answer here:
Hye guys, I'm 19 and I want to learn music theory to start improvising solos and composing songs like king krule, cosmo pyke and yellow days, but I don't know if I'm already late to start. I already know how to play guitar and i think i'm decent at least. If you were me, would you choose a teacher or is it possible to learn by myself? Sorry for the bad english, i'm from argentina lol Thanks guys!
