String theory [ST] is a relatively recent development in theoretical physics that reveals the fundamental, irreducible building block of the universe to be an inconceivably tiny vibrating string. Everything is built of these strings. Hence, ST posits a universe made of music. This work examines the implications of ST in a landscape seen as remote from physics, the human heart. As such it is an exploration of ST in the harmonic nature of life, existence, love, God and the universe.
