In this book, the author uses episodes from Mozarts life which illustrate a specific aspect of musical perception. He explores the mechanisms of musical memory - how is it mentally possible to memorise a fifteen-minute musical composition for nine voices, in two choirs? Is this ability due to a listening technique? To an emotionally-based one? What mental operations are at work in musical memory, in general? Bernard Lechevalier is a neurologist specialising in neuropsychology, and a professor of neurology and medicine in teaching hospitals.
