Voicing will be referred to differently depending on the saxophonist you ask. Many wholly embrace voicing and a few will refute it. Nonetheless, we all voice, no matter what we happen to call it. Voicing is an essential element of saxophone technique. Playing through the entire range, the saxophonist should not have to alter his embouchure, but instead compensate with the oral cavity to produce an even and consistent tone. Building this skill takes a lot of persistent practice. Some exercises may be mastered in hours and other may take several weeks.
