Music therapy is a verbal and nonverbal communication technique which uses music and sounds with therapeutic means in order to improve people's health problems. The focus is to use music to reach the following goals: recovery, maintenance and improvement of mental and physical health.

It may also be defined as the scientific application of sound, music, and movement through the training of hearing and sound performance, which integrates cognitive, affective, and motor skills, by the development of consciousness and promotion of the creative process.

The basic idea is to recognize that a great percentage of illnesses are caused in the brain, which in turn transmits a particular stimulus to any part of the body which eventually translates into an illness. The aim with music therapy is to stimulate the brain with music-sound stimuli to help people relax and eliminate what was causing the illness.

The scientific fundament emphasizes the potential emotions have to treat illnesses. The musical rhythm causes an increment in the motor brain cortex, emotions are instilled and then transform themselves into chemical substances capable of influencing the immunologic system and other healing mechanisms in the body.
