The invisible vibration of sound and music affect every cell of your body, having an immediate effect on your mood and energy.
The Musical Pharmacy of Prof. Christoph Rueger at the University of Art in Berlin includes "The Phantom of the Opera" (Andrew Lloyd Webber) for Depression, Mozart’s Piano concerts in d-minor for Despair, Beethoven’s Moonlight Sonata for Insomnia, and Johann Sebastian Bach’s Chorals to increase your vitality. 
According to oriental traditions and modern research, different notes or tones are directly influencing specific organ systems and energetic qualities within us.
The musical note F, for example, strengthens our heart, and helps us feel love, compassion, and understanding.
The musical note G helps us communicate and takes away pain. If you need some extra physical energy and bring forward feelings of optimism, hum to the musical note E.
Blow the clouds away and sing. Singing exercises the facial muscles in the same way as laughing, switching on our happy mode in our brain.
Sing a little tune from your heart ;-)
