Music can be powerful emotionally. It has the ability to uplift and engage you in a way that most other things cannot. Music can reduce anxiety and depression and improve emotional expression, interpersonal skills, self-esteem and quality of life.
Studies have shown that by listening to self-selected music it can cause a heightened emotional response and can distract attention more effectively. Music can also give a sense of increased control in unfamiliar or threatening situations by acting as a stimulus that is distracting. MacDonald, Raymond A.

Music can activate limbic and paralimbic structures, such as the amygdala, the hippocampus, the nucleus accumbens, etc. that function abnormally in patients with a high depressive component. At the psychological level music can engage several social functions, can increase communication and social cohesion and can promote empathetic relationships.
