The 1997 book by Don Campbell, The Mozart Effect: Tapping the Power of Music to Heal the Body, Strengthen the Mind, and Unlock the Creative Spirit, discusses the theory that listening to Mozart (especially the piano concertos) may temporarily increase one's IQ and produce many other beneficial effects on mental function. (1) Campbell recommends playing specially selected classical music to infants, in the expectation that it will benefit their mental development. (2) Playing Mozart to animals decreases anxiety and stress and allows them to be more receptive to commands from their owners.

After The Mozart Effect, Campbell wrote a follow-up book, The Mozart Effect For Children, and created related products. (3)Among these are collections of music that he states harness the Mozart effect to enhance "deep rest and rejuvenation", "intelligence and learning", and "creativity and imagination". Campbell defines the term as "an inclusive term signifying the transformational powers of music in health, education, and well-being. (4)It represents the general use of music to reduce stress, depression, or anxiety; induce relaxation or sleep; activate the body; and improve memory or awareness. Innovative and experimental uses of music and sound can improve listening disorders, dyslexia, attention deficit disorder, autism, and other mental and physical disorders and diseases."
