Practice is severely overrated
Practice counts very much when it comes to drawing and animating the way I want to, I've practiced a lot and I've gotten pretty good at it but these days I barely draw. The artists I look up to have gotten good by drawing all the time.
Experts are those who know where to look to find information when they need it, trying to know everything by memory is a fool's errand.
When you use references you still need to be good at drawing, only a minority of artists draw without reference, that's not what I want to do.
Quoting some other niggas
Thank you, I've actually tried to study most of these things on my own a year ago, before I stopped trying (now I started again, but as I said I'm only messing with the synths and recreating songs, not writing; I recreated Azure Day by 憂鬱 with very good accuracy for example using Vital and Reaper). I can already read sheet music because I started playing classical piano three years ago (I regret not starting as a kid like the others, but still), but despite having watched many videos I can't understand stuff like the circle of fifths, maybe I'll get it once I start actually writing my own songs.
You really ought to get a MIDI keyboard
I use my pc and I thought about getting a MIDI keyboard but despite my experience with the piano I am extremely uncoordinated and I can't play by ear, improvise or sight-read, so it's not like I would need it much, but It'd still be useful when I'm using Vital to play chords quickly and test the sounds. I have a lot of stuff plugged to my computer, I just bought a graphic tablet for my art and I barely used it, maybe I should make a thread here and ask others to tell me what to draw but I'm too high-inhib for that.
