Week 44: Relating Sound to the Anatomy (Part 4)

Continuing my series on relating 'Sound to the Anatomy' when training. I'm dealing with Volume this week.
1. Generally, an increase in volume is achieved by an increase of air pressure. This thickens the true vocal folds, referred to as thick folds.
2. When we contract the abdominal muscles of the Breath Support System, air pressure increases, the energy level heightens & Volume increases.
3. When less volume is required, the air pressure is reduced causing the true vocal folds to vibrate at the very edges, which thins the folds.
4. In piano #singing, the higher notes require a relative increase in air pressure, & the muscles of the breath support system must be engaged.
5. The bel canto exercise of messa di voce, is actually the transition from thin to thick vocal folds, & back again, on one sustained pitch.
