Hello Greg, wanted to thank you for the wonderful things you are doing with WindWorks. I have been struggling with bad playing habits the past 30+ years since studying with Chicowicz at Northwestern while still playing gigs and killing myself in the process. I am one of those students who struggled in college with some bad undergrad teaching methods. I have tried everything under the sun to make my playing more efficient but to no avail. Your ideas have saved my playing life and made playing the trumpet so much easier and fun again. As a public music educator K-12 the past 30 years, I highly endorse your teaching methods and approach to playing wind instruments. Best wishes to you and your family and continued success.
