A viewer asks: “Does the harp somehow heal our actual hearts? Is it because of the pure vibration without stops between the strings and the person?”

What the harp does is promote unity between you and God because it helps raise you in vibration to be on God's wavelength, and that can mean, through that closer presence in the awareness, more can be given to the music listener that is of a lofty and loving nature. This is the real source of satisfaction people feel from a satisfying concert performance they witness. It is not just the skill and prowess of the musician, nor even necessarily the detailed composition being rendered musically, although some music is more lofty in nature than others as generally perceived, it is the reunion with the divine that is brought about in the act of immersing oneself in the music coming forth that transforms the person in some way to a more lofty, happy state of being.
