I've just bought this book by John Ridgeon, and I'm trying to make best use of it to help me with cornet playing (I'm an adult rebeginner). If anyone knows about this, I'd appreciate some help.
He starts out talking about breathing, which I actually get (diaphragmatic vs chest breathing). Then goes on to resistance from the glottis and I'd better quote:
"The basic requirement of the glottis is to control the sudden gush of breath from the lungs following the contraction of the abdominal muscles. It is now necessary to establish it's further duties, as a volume controller. ... The glottis should be considered as a fine regulator operating small changes in dynamic level too subtle for the powerful muscles of the abdomen."
Now I'd always taken the flow of air as regulated by the gut - that's just how what I do feels. The glottis is for talking! Is he on the same planet? Does he want me to 'voice' notes?
