Since you’ve been spitting hot takes here’s one of mine: dog couples are boring as fuck. Not sorry

Learn some chords (major and minor) and then use them to play some of your favorite songs. That’s a great way get started and have fun. For music theory, start by learning what chords make up the major and minor keys. And learn some intervals. I used YouTube when I started, but it’s full of slop/click content now. I’d suggest getting a few lessons in person. Anyway, lmk how it goes - tag me if you have any questions. I’ll help you out for free. I’m a musician and songwriter. And oh yeah last point, you gotta start to develop your musical ear. Greatest strength as a musician imo
