Why the first resonance decides whether you yell, hoot or mix, shown on VoceVista and then tested live on real singers.

Kelley Hijleh, associate director of the Singing Voice Science Workshop, narrows a famously dense topic down to one thing: the first resonance in the treble voice. Using VoceVista displays and a people-standing-in-line analogy, you'll watch the first resonance meet the third, second and first harmonics and hear the amplitude jump each time, plus what goes wrong when it falls below the fundamental. She contrasts the yell and the hoot as primal sounds, makes the case that a good mix deliberately avoids over-relying on either, and shows how twang, nasality, volume and vowel choice add high-frequency energy. Live scales, belt-versus-mix comparisons and two student lessons follow.
