My immediate thought is: Are there any music centres nearby? As someone whose youngest has just started at conservatoire last September (the violin is her main instrument, but she will play anything she can get her hands on) she didn't study music in school at all (because the music provision was terrible), although she would join in bands when they performed etc.

However she went to the local music centre since she was young, was in several groups/bands there and that was how she grew her skills, found a tutor etc etc.

Do you have anything similar?

You can then work on the school, maybe get on the school board and make changes.
