In Musicophilia, neurologist Oliver Sacks shows that music is far more than entertainment—it is deeply connected to the brain, identity, and memory. His clinical stories reveal unusual musical experiences. Some people with hearing loss develop musical hallucinations, hearing songs that are not actually playing. One man, after being struck by lightning, suddenly felt compelled to become a pianist. Others with severe amusia cannot make sense of music at all, hearing it as noise rather than melody. Sacks also highlights music’s therapeutic value. Rhythm can help people with Parkinson’s disease move when they are otherwise frozen, while familiar songs can awaken memories and emotions in people with Alzheimer’s. Studies of music and memory suggest why this happens: familiar songs engage emotion, movement, and autobiographical memory at the same time. A song from the past can bring back a person, place, or feeling with remarkable force. For people with dementia, personalized music can encourage recognition, conversation, and connection. Music, Sacks suggests, can remain meaningful even when words and memories begin to fade.
