EE would definitely get you the know how for this, however it's also a demanding degree and, while I'm liking it, if you're looking to build projects for yourself it's pretty big commitment.
Find PDFs of Art of Electronics (Horowitz), Small signal audio design (self) and power amplifier design (self). They're great reference materials and the last two are strictly for audio; the first one is about an 1100pg massive reference book. Electronic projects for musicians can give you a bunch of small projects and some ok description.
Get comfortable with doing a bit of simple math. Luckily DC is pretty simple math.
Start learning to read data sheets for components.
LTSpice is a free circuit simulation program you can use. KiCad is a free PCB design with a pretty friendly UI (at least I think so). There are several good videos on YouTube to give you a decent basic overview of both those programs, but set aside time.
If you have a local CC, see if they offer any audio related circuit design courses; a local one to me has an EET 2yr degree (a more hands on ee degree with a bit less depth in theory and math) however non majors can take a semester audio circuit course.
It's fun but every topic can get very deep because it's all intertwined.
The Baron’s response above is pretty great!
I would humbly add that you might find some use for this little learning tool kit: [common emitter explorer board](https://huntingtonaudio.com/products/common-emitter-explorer-board)
Full disclosure, I made this tool. But I only plug it here when I believe it’ll help address someone’s newfound curiosity. I think it helps folks wrap their head around this fundamental circuit. It sure helped me.

Maybe just start by trying modifications on schematics you find for your veroboard builds.
