Yes, and very much so.
Not that the lessons weren't crap or the teachers weren't extremely disparaging of music that wasn't classical music.
Not that the lessons weren't boring to 99.99% of pupils.
It's just that I happened to be that one weird pupil all the info was adapted to, and I sucked it in.
Still hated every single music teacher though, especially the first one, the one who taught us notes and how to play a recorder.
In '63 or so, my buddy Wim played two wrong notes in a row, and that teacher unceremoniously, with a flat hand, slapped him in the face.
I shouted "a-hole!", and much to my surprise wasn't slapped, but only sent to the corner, to stand there with my face to the walls.
At that point I knew that the teacher was afraid of the consequences of his actions.
Modern times had arrived.
