A technique of receptive music therapy to induce relaxation has been developed in the university hospital of Montpellier: the "U" sequence. The musical sequence lasts 20 minutes and is made up of several phases that progressively induce a relaxed state in the patient. This effect is obtained by modulating the rhythm of the music, the orchestral formation, frequencies and volume. The phase of maximum relaxation is followed by a stimulating phase. These musical sequences have been specially designed by the music publishers Music Care©.
