Randomly running through web pages on embouchure exercises/strengthening, I came across one on Caruso exercises on a trombone players site. The one thing that struck me was the advised technique of keeping the embouchure set and breathing through the nose during the exercises. That is antithetical to everything I've been taught on breathing during exercises. Does anyone here believe there is a place for breathing through the nose in certain exercises so as not to disturb the embouchure as a way to strengthen the embouchure? First time I'd ever heard that.
