A spectral analysis program that provides real-time visual feedback on pitch and voice quality.
The EVT method is based on the concept of "figure-hugging" – the ability to manipulate and control the vocal tract, including the vocal cords, tongue, lips, and jaw, to produce a wide range of vocal qualities and emotions. Estill's approach emphasizes the development of a flexible, responsive, and coordinated vocal instrument, enabling singers and voice professionals to access a broad spectrum of tonal colors, dynamics, and articulation.
