When he was first introduced to the idea that human consciousness has been evolving over the centuries and millennia, Brien Masters discovered the possibility of gaining insight into this phenomenon by examining the musical styles of various classical composers. Following years of musical study and practice, in Mozart's music he detected a reflection of humanity's emerging consciousness of selfhood and individuality.

Two hundred and fifty years after his birth, Mozart continues to be acknowledged universally as a musical genius. Recognition of his work, however, goes beyond the pleasure we derive from listening to his music. In the 1990s, psychologists discovered the so-called Mozart Effect, the notion that listening to Mozart enhances mental capacities and even health. In this study, the author considers Mozart in relation to the evolution of human consciousness.

Could Mozart's music affect changes in human makeup? Masters studies Mozart's musical style and considers the nature of the human "I." By analyzing Mozart's compositions, the author shows how the principles of the "I" are particularly evident his music. Masters tells us that his book may be read as his attempt to "describe the self's journey toward the richness of Mozart's musical style [and] to shed Mozartean light onto the self as the central element in the human constitution. The former perspective is a comment on the significance of his genius appearing in the second half of the eighteenth century. The latter has relevance, among other things, for the debate on and understanding of the so-called Mozart Effect today."
