Initially, workouts consist of sessions of listening to very high frequencies that stimulate the pre-natal sounds and reproduce the stages of development from an audial point of view. This training makes it possible to switch ear dominance, reteach the listening process. These passive exercises, which consist of listening to specific frequencies, are gradually combined with active exercises utilizing the voice to maintain the lessons learned. For language learning and transformation of words and pictures, beginning with pre-natal sounds enables a person to learn a language quicker and more efficiently. The first fifteen days usually require about two hours a day.
Subsequent sessions are shorter, with up to one or two months between each session.
There is a story that says Dr. Tomatis visited a Benedictine monastery in France in the early 1960 s following the second Vatican Council. One of the decisions the council had made was to eliminate the traditional chanting for a more constructive use of time. Gradually changes took place among the monks. They became more lethargic and less motivated. Sleeping more and eating more was no help.
