Hi Greg,
I’ve been doing WindWorks for several months now – now beginning Ruby. Just had an epiphany on Body Concert Hall. I emotionally felt that I had understood it, accepted it, and did the Check-Ins etc. But hadn’t really FELT the difference on the horn (and my body) until now, when I stumbled across something.
I was warming up and had my PRACTICE MUTE in (so as not to disturb others in the house) and was doing octave slurs from Pedal C to low C (eighth notes). I could hear the practice mute sound quality change on certain slurs and not others. Some slurs sounded nasal and pinched, and others were open and full.
I began to experiment with ways to alter the sound (dropping jow, opening/closing aperture, opening throat) and suddenly I could control the nasally sound, and could opening and closing the tone at will. When my throat was closed, I got the nasal sound, but when my throat was open, not only the sound became open, rich and full, but I could feel a vibration down my neck and into my sternum that I hadn’t noticed before. The horn was actually playing me now.

Thanks Greg! That one breakthrough is worth the entire month’s subscription!
