I just read and watched your resposes to questions regarding the shape and movement of the lips. Maybe you can help me a bit too. I did learn a lot from that but here’s my situation: I can whistle very well. Following the movements of my lips when I’m whistling is just like you are explaining for playing of the trumpet. I just am having a tough time getting it to work on the horn. Perhaps I am pushing the horn too tightly to my mouth? I can get the middle of the upper lip to vibrate and sometimes I even get some high notes to just pop out. Could it be I’m just trying too hard. My lips are very tired and it has adversely affected my normal way of playing…..I’m exhausted. If I could just amplify my whistling it would be great. My range is very good and no pushing the air when I whistle. I simply comes out naturally. Am I trying too hard?? Oh, and how do I keep my jaw down? I’m trying but don’t understand the feeling. I love your lessons and your methods….just wish I could just jump in and do it right away…..before we get back to bands in January (I hope).
