What is Jawbrato?
1.
1. Shaking of the jaw concurrent with the pulsations of vibrato during singing.
2. Vibrato resulting from the conscious manipulation (wagging) of the jaw found in some non-classical vocal traditions.
3. Satellite shaking of the jaw, due to muscle tension, in reaction to vocal vibrato.
"From the first row, we could see the soprano had some major jawbrato when singing high notes."
