I know this forum has a diverse membership when it comes to musical backgrounds. From beginners to grizzled vets and pros, we all like to noodle, play, and even write by ear, which is great! But IMHO, a little bit of theory goes a long way to help progress in both knowledge and skill when it comes to playing guitar and writing music. I still have tons to learn myself. Certainly no expert. My music education was long ago, and these days, I mostly try to remember all that I had forgotten. Which is how I discovered Rick Beato's Everything Music youtube channel. I think Rick's approach to theory is great, mainly because he's also a guitarist and fan of rock music like so many of us (also jazz and other genres). So among his traditional, more educational videos, are also a series of great song analysis vids he calls "What Makes This Song Great?" In that series, he breaks down various components of a popular song and explains everything both from a theoretical perspective, and also just as a fan. It's a great and engaging way to pick up on some theory and production basics and also just to hear the deconstructed/isolated tracks of some great songs. Here are a couple of those examples followed by a live "Music Theory Basics" video he just released yesterday. I wouldn't say it's for beginners (most of his videos requires some fundamentals), but he covers some building blocks for music theory that are worth checking out. Anyway, just thought I'd share for anyone interested!
