A research of the relationship between music and psychology is welcome in oncology psychology. We could say that music and psychology are two communicating vessels;   The overall objective is to try to treat or even improve oncology depression with melotherapy.  The purpose of the research is to try to make an assessment of the personality of the patient, highlighting the main problems and psychic peculiarities of the patient, and drawing up a  specific therapeutic plan for each patient.  Melotherapy does not replace chemotherapy or other psychotherapy but associates with  them. It is not a universal remedy for all the the disorders.
