Hello,
This is a PDF that has been shared by many band directors around the country. It is designed for those moments where you just "don't know what to do" and you need some help. Who knows, it might save you a trip to the music store or time where you have to leave your instrument at school for repair.
Good luck and just remember, if you are still "stuck" email me at mdelligatti@nssd112.org. We'll make a plan to take care of your needs!
Mrs Delligatti
