A professor of Music Analysis dies and his soul travels to meet the Children of the Light, who inquire about how music is learned on Earth. As a teacher on this subtler plane of existence, he is called on to override the merely rational way of understanding and communicating. Instead, the evolution of sound is used as a metaphor to illustrate the journey of light into matter and the dualities generated by their opposition. The message of this imaginative story is about the linking of human beings to a higher-realm form of communication incorporated into the reality of the Earth of the future.
