My impression is that a sense of rhythm, which has no analog in language, is unique and that its correlation with movement is unique to human beings. Why else would children start to dance when they're two or three? Chimpanzees don't dance.

If we wish to know about a man, we ask 'what is his story--his real, inmost story?'--for each of us is a biography, a story. Each of us is a singular narrative, which is constructed, continually, unconsciously, by, through, and in us--through our perceptions, our feelings, our thoughts, our actions; and, not least, our discourse, our spoken narrations. Biologically, physiologically, we are not so different from each other; historically, as narratives--we are each of us unique.

Given her deafness, the auditory part of the brain, deprived of its usual input, had started to generate a spontaneous activity of its own, and this took the form of musical hallucinations, mostly musical memories from her earlier life. The brain needed to stay incessantly active, and if it was not getting its usual stimulation..., it would create its own stimulation in the form of hallucinations.

The rhythm of music is very, very important for people with Parkinson's. But it's also very important with other sorts of patients, such as patients with Tourette's syndrome. Music helps them bring their impulses and tics under control. There is even a whole percussion orchestra made up exclusively of Tourette's patients.

I feel I should be trying to complete my life, whatever completing a life means.

I think the brain is a dynamic system in which some parts control or suppress other parts. And if perhaps one has damage in one of the controlling or suppressing areas, then you may have the emergence or eruption of something, whether it is a seizure, a criminal trait - - or even a sudden musical passion.

There is no one part of the brain which recognizes or responds emotionally to music. Instead, there are many different parts responding to different aspects of music: to pitch, to frequency, to timbre, to tonal intervals, to consonance, to dissonance, to rhythm, to melodic contour, to harmony.
