A really lovely teacher. She's relaved generally, and if you take a genuine interest in learning technical aspects in music (it has NOTHING to do with being in band, I was not in band) then you're good to go. Just be a respectful student who takes an interest, though really I'd think that'd go without saying for any teacher.
she is awesome because she organises so many things for us to do
She will only be useful to you if you are in the band, if you're not a part of the band then you get ignored. She also has favourites which is not fair to other students
