This is an addendum to my previous advice to compose your own upbeat music and learn to play it.
If you’ve been fiddling around with your instrument for a little while you may have had the pleasure of accidentally producing a ditty or two, and you may even start hearing some music in your head that you’ve never heard anywhere else. Congratulations! You have enough crazy in your head to compose music. The rest is work and drudgery.
Nah, just kidding, composing is about as much work as stream-of-consciousness prose. The trick is to learn a thing or two about common musical structures so you don’t have to reinvent the wheel from scratch every time. It’s like shitposting on forums and blogs that way. Your first seop should be the lessons on MusicTheory.net, which will take about four hours to absorb. It could also be your last stop—there’s enough information in those fundamentals to support your entire songwriting career. Honestly, you don’t need to know a lot to do music really well, you just have to practice a lot.
Your next step is optional. Pick up a software program that lets you see and hear your music as you write it—this instant feedback is invaluable. You can write by ear very easily this way and ease can make the difference between frustration and a creative flow state. I recommend putting in a couple of hours to read the manual and customizing the hotkeys for that reason. People tend to be impressed with how quickly I can put out music and it’s because I’m accustomed to the hotkeys I’ve set up in TuxGuitar. If you aren’t a guitarist you’ll have to find something analogous to TuxGuitar for your preferred instrument (although it’s also good for keyboard and percussion—and free), just make sure it’s not “mixing” software because that’s something else and adds unnecessary complexity.
Last step, also optional, is to pick up a book about improvisation and composition. There are a ton of these out there, and you can just grab one at random from the library because it’s an art, not a science, and not a particularly difficult art once you’ve your instrument and absorbed the fundamentals of music theory.
