Do you experience the playback mode of songs in your brain? These are described as earworms from the German word ohrwurm which means "stuck song syndrome." Daniel J. Levitin, a former rock musician, session musician and record producer, explains this as a function of the auditory short-term (echoic) memory. This book has a neuropsychological outlook on how music affects our brain, mind and spirit. The author is a practicing neuroscientist and runs the Laboratory for Musical Perception and Cognition at McGill University. An entire chapter discusses the importance of foot tapping, rhythm, loudness, harmony and musical pulse. His discussion of groove as the quality that moves the song forward, the musical equivalent of a book that you can't put down, engages your musical sensibility with examples from Peter Gabriel, Bruce Springsteen, the Pretenders and especially Stevie Wonder's "Superstition." In Great Britain an experiment on fetuses demonstrated that children at age one could recognize music exposed to them in the womb. One musical piece was singled out for each baby from Mozart to the Back Street Boys. The author shares his views on The Mozart Effect, the claim that music listening improves task performance. The reader will have a lot of fun with the author's references to popular music and personalities. Scan the book's index; you will find Eminem, Louis Armstrong, AC/DC, Austin Lounge Lizards, Rick James, Prokofiev, Otis Redding, Paula Abdul, Johnny Cash and others.
