Musicophilia is an exploration of the power of music to heal, to encourage and support in adaptation, and to inspire resilience in the most challenging of circumstances. Many of Oliver Sacks’s patients and correspondents are musicians compelled to fight for their talents and abilities because of a neurological condition. One man named Jacob, who was slowly losing the ability to hear higher octaves, adapted by learning to compose in lower octaves and then transpose them. He noted, “You work with the ears you have, not the ears you want” (147). Another neurologist named Dr. Jorgensen trained himself to perceive stereo music with one ear by using visual cues and the memory of how it sounded; Sacks referred to this as a “reconstruction of function” (157).
Musical memory is both procedural and emotional, and these types of memory tend to be stronger and outlast other forms. They are, seemingly, among the most important aspects of being human. Thus, when a person’s neurology has left them feeling as though their humanity is slipping away, either as the result of memory loss, debilitating seizures, or otherwise, music brings them back to themselves and to their humanity. The fixed action patterns which are learned when one plays music become imprinted in the motor cortex and remain there, and although many of these patients will forget about music when it is not present, they only need to sit in front of a piano to begin playing as they once did.
Musical ability can also come later in life as a compensatory response to brain damage, blindness, and other conditions. This “cortical plasticity” (242) is indicative of the adaptability of the brain. Sacks explains that, in particular with damage to the left hemisphere, the now-less inhibited right hemisphere becomes more active. This can lead to talents that were previously absent:
[T]he right hemisphere, which in normal circumstances has only the most rudimentary linguistic capacities, can be turned into a reasonably efficient linguistic organ with less than three months of training—and that music is the key to this transformation (242).
For people with aphasia, who have lost the ability to speak after a seizure or stroke, music can help them find their voice again. Similarly, Parkinson’s disease affects the perception of flow of movement, but can also affect flow of speech, thought, and feeling, and music seems to help people with Parkinson’s find control and rhythm again. It has a similar effect on people with Tourette’s, many of whom find their tics controlled while listening to music. Sacks personally lost the ability to walk with rhythm after a leg injury and found that the predictable rhythm of music helped him find his own internal rhythm again. People like Clive Wearing and Louis, who could not remember their past, were able to remember music, and to sing, play, and enjoy it as they always had. Sacks is perhaps most deeply moved by music’s effects on people with progressive memory loss from dementia and related conditions: As they slowly slip away, music provides them joy and induces memories long forgotten:
I had read Nietzsche’s notes on physiology and art as a student, many years before, but his concise and brilliant formulations in The Will to Power came alive for me only when I came to Beth Abraham (Hospital) and saw the extraordinary powers of music with our post-encephalitic patients—its power to ‘awaken’ them at every level: to alertness when they were lethargic, to normal movements when they were frozen, and, most uncannily, to vivid emotions and memories, fantasies, whole identities which were, for the most part, unavailable to them (283).
This is also true for those with dementia and Alzheimer’s, who find that music brings them joy and solace where they otherwise cannot find it.
Neuroscience is now a fairly developed field, but the study of music in relation to neuroscience is somewhat more neglected. Research was sparse until the 1980s but is seeing a resurgence as neurologists around the world discover how music can be used therapeutically. Sacks believes that music is innate to humans: No other species uses it creatively to the degree that we do, and music has been part of nearly every human culture for thousands of years. As with much of neurology and psychology, however, questions of nature versus nurture are unresolved:
Our auditory systems, our nervous systems, are indeed exquisitely tuned for music. How much this is due to the intrinsic characteristics of music itself—its complex sonic patterns woven in time, its logic, its momentum, its unbreakable sequences, its insistent rhythms and repetitions, the mysterious way in which it embodies emotion and ‘will’—and how much to special resonances, synchronizations, oscillations, mutual excitations, or feedbacks in the immensely complex, multilevel neural circuitry that underlies musical perception and replay, we do not yet know (xii).
In recent years, functional MRI (fMRI) and EEG scans have shown that musicians have a particular brain shape that is unique to them. The corpus callosum, which connects the left and right hemisphere, is larger, and the auditory, visual, and motor areas of the cortex contain more than average gray matter. What this means is that musicians can be identified by fMRI alone “without a moment’s hesitation” (100)—something that is not true of any other profession. Sacks points out that it is not known whether this difference is acquired or genetic, but it is likely a combination of having a genetic predisposition and the environmental stimuli to bring it to life.
Certain brain areas are active during engagement with music, whether a person is listening to it, imagining it, or hallucinating it. There are also striking similarities between epileptic seizures and musical hallucinations, as both seem to be uncontrollable impulses sent out from the basal ganglia. People who experience musical seizures are thought to have a dysfunction in their basal ganglia. People who become blind often develop musical hallucinations or a savant-like ability in relation to music, which Sacks reasons is a compensatory response to the lack of visual stimuli; the visual cortex is thought to be used for other purposes when a person becomes blind, as it expands the remaining senses.
More generally speaking, music moves people to emotion, whether they want it to or not. Music also impels people to move—to tap, sway, and hum along to the melody they are hearing. It opens new doors to procedural and emotional memory, perhaps more strongly than anything else. For people with Parkinson’s disease or Tourette’s syndrome, music helps them find control and rhythm again. People who cannot perceive tones or pitch may still maintain a deep emotional appreciation for music, and those who have no emotional response to music may still appreciate it technically. All of this suggests that multiple brain areas are involved in the perception of music. For people like Clive Wearing, music lasted when almost all other memories faded, showing how music permeates the brain so deeply and widely that it cannot be easily erased. Still, there are people who after a stroke may lose their ability to appreciate music, and this can be an extremely upsetting experience. Throughout the book, Sacks constantly asks, “What could be the neurological basis of this?” (13) and encourages his readers to do the same.
Music is human; “for virtually all of us, music has great power, whether or not we seek it out or think of ourselves as particularly ‘musical’” (ix-x). Almost everyone can learn to play music, even if they cannot read it, and almost everyone has some appreciation for music as well. No one is sure where, when, or why humans began producing music, or whether music is a unique ability or an amalgamation of other skills (language, art, expression, motor coordination), but music seems to be ingrained in the very essence of human experience, and songs and melodies that affect us are usually never forgotten. In fact, memories of music remain so pristine that music in dreams, hallucinations, and musical imagery is often an almost exact replica of the real thing. Music is so important to the human mind that, when deprived of music—through hearing loss for example—the brain will often create music on its own, resulting in what Sacks terms “musical hallucinations.” Furthermore, human ears have evolved to hear approximately 20,000 unique tones. While this type of hearing is useful in tonal languages like Mandarin, for instance, it is much more curious why those who speak languages like English, which do not rely on tone for interpretation nearly as heavily, still developed the same level of hearing. Sacks believes it must be that humans evolved to appreciate and create music.
Musicality comes in a wide range, from those with amusia to those with savant-like abilities and everything in-between. Musical ability can be lost or gained as the result of a seizure, stroke, or other brain injury, but seems more impervious to general memory loss, as in the case of Clive Wearing. Music allows people to remember events they might otherwise have forgotten, and stirs emotions long lost in the depths of Alzheimer’s or grief. Some have the ability to identify exact tones by ear, known as absolute pitch, while others cannot distinguish tones at all. People with Williams syndrome have deficits in many general abilities but excel in music. Williams syndrome in particular suggests that there is a specific musical intelligence, that music is a cognitive function, and that music is innate. Around the world, music causes a physical response in people; we tap, sway, sing, and respond, and Sacks thus theorizes that the auditory and motor cortex are likely directly connected. The rhythm and harmony of music also serves to form communities, break down barriers, and provide a sense of unity. Added to this, “music calls to both parts of our nature—it is essentially emotional, as it is essentially intellectual” (312). As intellect and emotion are the pillars of human experience, it seems too that music is at the forefront of the human experience.
