That's a great idea! Every little bit helps. It also doesn't hurt when there are school board members at your concerts...better yet when they have kids or grandkids in your classes.

Some of the little things I've found useful:

1. Performing at a school board meeting and explaining your program.
2. Performing at a school-site council meeting and explaining your program.
3. Inviting school board members and administrators to all your concerts.
4. Inviting anyone you can to watch you teach a class.
5. Putting on a series "Informances" for parents, where you teach a lesson while demonstrating and explaining the methods to your madness as you go along. Many parents think classroom music is just playing games and singing songs, and are blown away with what their kids can really do musically!
