The Science of Voice: Techniques for Sustainable Vocal Performance
Projection isn't about pushing harder, it's about knowing where to put the effort.

They break down diaphragmatic support, frontal resonance, and nasalized projection as alternatives to straining the throat, plus why regular vocal breaks and character-voice consistency both come down to the same underlying skill: effort management.
