The Jo Estill Lectures: Graphing Sound (Acoustics)

Have you ever wondered what it would be like to sit in a classroom with Jo Estill? This course takes you back in time to view Jo Estill lecturing on acoustics.

“In the mechanical sense, a (voice) register can be likened to the gears of a car. In the low gear of a car, you can go up to perhaps 18 miles/hour before you must shift into the next higher gear to go faster. Perceptually, registers have been defined as light or heavy.” (Jo Estill)

The Jo Estill Lectures: Anatomy & Physiology of the Vocal Tract

Ever wondered why we steer clear of Head/Chest Voice terms in EVT®? This lecture is for you!

“Instead of Head Voice people might better have called it Head-feeling Voice because the sensation that accompanies the higher notes is made with muscles that form the vocal tract or tube, and this action is felt in the head. But your voice is not made in the head.” (Jo Estill)

The Jo Estill Lectures: Breathing & Effort in EVT®

Explore effort and debunk breathing myths with this enlightening lecture!

“Many speakers and singers devote daily practice to diaphragmatic movement; however, research has shown that while we can voluntarily inhale, we cannot voluntarily contract the diaphragm. The Estill Voice Model addresses breath and support as separate and variable skills because of the complex and dynamic nature of breathing for high-level vocal performance.” (Jo Estill)

The Jo Estill Lectures: Origins, Differences & Advantages of EVT®

This course is for all voice enthusiasts and is a perfect accompaniment to your EVT® Level 1 and 2 studies or your EVT® certification training.

“Effort can be of many varieties. It can be steady, as when you press and hold; or it can be variable, as when you change pitches or intensity; or it can be intermittent, as when you emphasize consonants and de-emphasize vowels, as happens when you improve your diction.” (Jo Estill)
