To answer this question, we propose an extract from the book "Why Mozart?
The pedagogy of listening that has been set up uses sound material that contains either the mother's voice or music.
And this music is always Mozart.
I have of course experimented with everything that can be recorded acoustically: noises, musical messages, classical or modern, traditional or contemporary.
I have also tried to integrate music from other continents, especially from the Far East, India and Africa.
The results concerning the effects of music on the body and the psyche have never reached, in terms of dynamisation, what Mozart brings us.
This does not mean that I have given up all investigation, for whenever an unknown piece comes to hand, I subject it to experimentation.
Thus, Mozart remains almost alone in the process of treating listening, oral or written language, spoken or sung voice deficiencies. In my opinion, his music is one of the universals. It acts on everyone and everywhere.
To live, to vibrate, Mozart was especially gifted. Ready to lead others, men in their humanity, he knew how to lead them to where only the beautiful, the transcendent, the joy of living exist.
