I think the first experience playing is really important. I have found that the fastest way to get everyone going quickly is through an event i call "Squeak and Squawk"

I bring in clinicians and have them introduce the fundamentals of care and sound production and get them playing their first note or two.

I provide the clinicians with a package to work with, and handouts for the students binders.

This "Beginning Band First Lessons Pack" on Teacher's Pay Teachers were a great investment.
