Music and memory have always been inseparable. After all, Memory is the name of the Goddess who was Mother of the Muses. The Muses, according to the poet Hesiod, "were nine like-minded daughters, whose one thought is singing, and whose hearts are free from care...who delight with song... telling of things that are, that will be and that were with voices joined in harmony." They called on Hesiod to sing their praises but they did so with a challenge: "You rustic shepherd, shame: bellies you are, not men!  We know enough to make up lies which are convincing, but we also have the skill, when we've a mind, to speak the truth."
