Ok, so I had picked up some feeling for structures of music when I was self-taught, because you hear it and you sense it when you play. Now I was playing scales and arpeggios, I learned note names, I was told a bit about intervals and counting, but it was all sort of vague and bumbling along. When I saw your posts they reminded me of this bumbling "things aren't clear" kind of feeling: you probably bumble much less than I did.
I wanted to systematically build up my knowledge of skills. It's how my own teacher was taught and probably how most good teachers have been taught, but not everyone wants to go that route. I discovered I did.
