“Listening to music is not just auditory and emotional, 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 provokes.”
Neurologist Oliver Sacks, in the preface of his book MUSICOPHILIA, Tales of Music and the Brain.
