Lissemore walks teachers through sound waves, harmonics, resonance and the vowel 'resonance dance' — the science-informed foundation for smarter pedagogy.

If voice science has always felt like a wall of jargon, this session tears it down. Richard Lissemore takes you from the ground up: how vocal folds oscillate, why rapid closure (not frequency) creates a strong voice, what amplitude, period and wavelength actually mean, and how the harmonic overtone series stacks above the fundamental. You'll see why low voices sound richer, why sopranos' harmonics spread apart, and how the first two vocal tract resonances define vowels — including the "resonance dance" of ee-ay-ah-oh-oo and why the AH vowel causes so much trouble. Lissemore also shows where the science is currently being challenged. Ideal for teachers ready to trade guesswork for a map.
