Look, I'm a jazz player and do music pedagogy stuff. It's kind of silly to listen to Metheny about how to learn things, the dude was a complete prodigy (not an attack on your comment, just an aside). He was teaching at the most prestigious music school after attending for a year or some crazy thing. Music has a very small elite of people who's brains wired very differently and basically have super powers compared to the rest of us, and most of them have no idea how to explain how they learn/teach in ways that are useful to regular brains. I've met some of them, and they might as well be a different species. (Synthesesia is often part of it, I did a master class with a pianist who was basically tripping the whole time he played, listening to him describe his experience was so completely un-relatable to normal people.)
Some of those folks are also great teachers, but a lot of them just say the most completely useless advice because they can't even remember not being able to instantly play whatever they hear.
