The singer must make room for the listener, make room for friends, for family. How does she do this? By finding the core of who she is, and trusting it enough to stay there. The friends, family, listener, each at their own core, can come together in peace, in wholeness, in celebration.
What's the voice's story? What, the soul's? When the singer knows this, she can join her voice with the souls of everyone around her, and the collective chorus can ring out all the stronger, for her addition is strong and true.
