It's been about 2 weeks since I've started learning the alto sax (Yamaha YAS-575 "Allegro" w/Selmer Soloist C**, 2 1/2 Forestone Reed). I've played the Bb Clarinet for about 5 years. I've had to "loosen-up" a bit regarding my emboucher in order to play the lower register. I've noticed that the overtones, timbre and tone are much more sensitive to my actual throat, tongue and lip position. My teacher says to continue to experiment and find the combination that "sounds right" to me and the piece that I'm playing. Also, ..."that I will know and feel what's right" when it get's there. I'm not totally inexperienced when it comes to music having had formal voice training. Singing in the tenor range, I know about focusing my voice for "head, throat and chest voice" depending on the range. Is this the case for the Sax? In this respect, the clarinet seemed easier to focus.
