But which something new? Making electronic music means wearing a whole lot of hats:
This is just stuff off the top of my head. I'm sure I'm missing lots of stuff that I don't even know I don't know. And this is just making the music. Performing it and building an audience is a whole other set of hats.
If I spend the time learning everything I'm "supposed" to learn first, I'll never make music. Like most of us, I'm just an amateur doing this in my limited free time, fighting with my inner critic who's constantly telling me I'm not good enough. The last thing I need is to give that inner critic more ammo.
I do know a pretty good amount of theory for the genres I'm interested in because I find it interesting. But I disagree with anyone who proclaims what someone else needs to learn before they make music. If someone feels like their chord progressions suck and it's holding them back, then it's great to teach them some harmony. But if they're making techno and the bass line is sitting on the root note and the melody is just a four note chromatic riff and they love it, I'm not going to piss on their parade by shaming them for not learning something that may not matter to them.
Of course people work hard to convince themselves they don't need to learn something. Many of them are battling insecurity while trying to make something personally meaningful and present it to the world. That's hard enough as it is without letting other people gatekeep them.
