I am a 60 year self learning beginner. I started by watching you tube videos and was overwhelmed by the vast amount of information available. They all stress embouchure, you need to develope your embouchure to play the trumpet. So every time I picked up my trumpet to play, I would contort my face into this contorted mask. I could barely play a note my face was so full of tension. Then I came across Greg’s videos. No talk of embouchure, just RELAXATION . Lo and behold, I am actually making progress!! Slowly ,but progress!!! Thanks Greg, I am enjoying the course.
