I was reading Dave Liebman's "Developing a Personal Saxophone Sound" and he mentions something in his introduction that was like an epiphany for me. He said that Joe Allard would tell him that "To blow is to breathe, there in no difference." It suddenly hit me that this was the key to playing relaxedly and naturally. I've recently been working on lessening the tension in my body and mind whenever I play. This quote is really great in reminding us how it feels like to be relaxed and natural whenever we play. I've been working on this aspect the past week and I have to say it definitely improved my playing. Whenever I think of blowing in the horn as if I was breathing, I would get a better sound and better feel overall. There's definitely a change in the way I play whenever I get it right, no matter how small it seems right now. I'm sure in the long run, this new habit will help my playing even further. And the change is not just physically (embouchure, lip tension, etc), but mentally as well. So whenever you feel like your tensing up when you play (especially with the lips and face), just remember to blow just like you were breathing.
