Hiphop originated as an offshoot of Jamaican ska, in the sixties. And song is healing. In and of itself. Pure Land Buddhists chant. Hasidic Jews sing and dance.
Christians sing hymns.
Muslims chant to Mecca. Americans live in such a visual culture, we need music for balance. Just singing one tone, toning, you can tune in to your being. Feel where your bodily limits are, where spiritual work is needed.
