I had no idea why tears so abruptly filled my eyes. I was crying before I understood why I might be crying. But the sense that the reaction meant something was as real to me as the tears.
I was seated alone in a packed crowd at Duke University’s stunning neo-gothic chapel, listening very intently as Scottish composer James MacMillan conducted his St. Luke Passion for choir and orchestra. The core text of the piece is taken word for word from Luke’s Gospel. The narrative begins as Jesus and his disciples prepare for their last meal together and ends with the last breath of Christ on the cross, the centurion exclaiming what the angry crowd moments earlier would not: “Certainly this man was innocent.” At any point, for any number of reasons, tears were certainly explicable, appropriate even. But there was something very particular about this moment which gave me pause months, even years, thereafter. My body seemed to rush ahead of any sort of conscious thinking. This was not a slow climb of emotion welling up as tears that eventually fell. I was not reckoning with a particular thought or concept that suddenly clicked. Rather, my eyes seemed to confess that my brain and body were up to something, caught up in an activity that the conceptual part of me hadn’t yet realized.
Neurologists and therapists experienced with the power of music wouldn’t find in my description anything much out of the ordinary. “Listening to music is not just auditory,” writes the late neurologist Oliver Sacks, “it is motoric as well: ‘We listen to music with our muscles,’ as Nietzsche wrote. We keep time to music, involuntarily, even if we are not consciously attending to it, and our faces and postures mirror the ‘narrative’ of the melody, and the thoughts and feelings it produces.”(1) The use of music in a wide range of therapies has long been known effective, helping patients who have difficulty with language, cognition, or motor control, even as the processes involved remain somewhat mysterious. Recent advancements in the field of neurology and brain-imaging offer much insight into the brain’s activity in the midst of music-making and music-hearing. With increasing light being shed on the brain’s plasticity (its ability to change) and music’s ability to activate and engage entire regions and networks within the brain, music is increasingly being engaged as an effective component of rehabilitative care.
