Hi, just posting to say that I have just been stuck in the same place, trying to get a sound on the leadpipe after weeks of making the new embouchure shape habit off the instrument. Your ‘wawawa’ and ‘yayaya’ advice has allowed me to lean into that first sympathetic buzz on the leadpipe, so thank you for sharing! It was a much richer buzz than what I’ve previously played, so that is now what I’m aiming for every time. I am hoping I have just experienced my first coffee moment.
