The title, borrowed from L. Frank Baum's book The Wizard of Oz, is an aphorism affectionately attached to Cope in the late 1990s. The reference reflects the many attitudes about his work with his computer music program, Experiments in Musical Intelligence; critics felt the results of this program lack heart.

Though Tinman covers many other aspects of Cope's life-from his love of the cello, to his days as a graduate student at the University of Southern California, and to his work as a composer, author, and teacher-the main theme centers on his search for self-identity.
