Historically, music has been used as treatment for brain disorders to help people restore language and motor skills. Learning new musical pieces can help trigger neuroplasticity which will help make new connections in the brain. These will often help people compensate for impaired parts of the brain.
Music is helpful in many ways. It is physical in the fact that it encourages to move to the beat of the music. This physical exercise can help with circulation, motor functioning and brain health.
Secondly, it is emotional. Music induces emotional states that help activate neurochemicals that will encourage positive moods.
Third, music is social and through collective experiences such as symphony, etc. it helps the person to engage with others rather than become isolated.
