The Modai Method is dedicated to the development of vocal function through the stimulation and not by the most common manipulation of the phonatory organs. The effectiveness of this practice is based on starting of ideal patterns of sound capable of implementing the synergistic interaction with the nervous system of the performer and listener. The acoustic model that follows, allows to enhance the performance beyond the average level, breaking the technical limits of the performer, optimizing psycho-motor resources and therefore achieve maximum results with minimum physical energy. In this context the performers can find themselves involved in a process where the sound itself will be able to guide and lead their own personal vocal development.
