The teachers know their rooms are basically "open" for co-curricular and clubs and tutoring and such within 30-60 minutes of their last class. Especially since this is a music teacher in a room with a nice piano, and there are only so many pianos on campus, she does have to be flexible with after school programs.
It is kind of "an offer you cannot refuse" so the update is, I got the room!!
at 3pm, and I did not have to ask. The fine arts coordinator did it for me, and she did not mention any fusses.
The teacher may not be happy, but here are the stats-
three piano teachers- one in the HS building who mostly does older kids, one in the academic hall "piano closet," and...me. Last year I taught a few lessons in an office with a digital piano, but a real acoustic piano truly is the best way to go, and the office got too crowded, anyway. I have to teach somewhere!
