A very good YouTube video resource here. Rick Beato is an Atlanta-based jazz, classical and rock musician turned engineer and producer. He’s just as much at home talking about Allan Holdsworth or Pearl Jam as Stravinsky or Hans Zimmer. He knows his AKG C414 from his Mozart K466.
He is currently producing a video series that comprehensively, generously, vigorously and engagingly marches through just about everything you can think of in music – harmony, jazz stuff, rock stuff, film composition, orchestration, ear training, recording techniques…
Well worth a subscription to his channel. He knows of what he speaks. There’s a Beato Book for sale too.

Interesting! I don’t know him and we’re in the same city!
