Ever wondered why music you love has the elemental power to move you so deeply that you can lose yourself in it as it sweeps you up it's as if you have become the music?
This is because when your body hears it, and you hear with every cell of your body not just your ears, it raises the vibratory output of all your cells until they match that of the music. This is called resonance.
When you function at a higher vibration than usual you begin to come into alignment with your greater self which is the energy of pure unconditional love.
So the music is allowing a momentary remembering of your true nature as you bask in the deliciousness of total loving connection. This happens at music concerts on a huge scale.
