The power of music and the plasticity of the brain go together very strikingly, especially in young people.

Nature gropes and blunders and performs the crudest acts. There is no steady advance upward. There is no design.

I think there are dozens or hundreds of different forms of creativity. Pondering science and math problems for years is different from improvising jazz. Something which seems to me remarkable is how unconscious the creative process is. You encounter a problem, but can't solve it.

There is only one cardinal rule: One must always listen to the patient.

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.

There are, of course, inherent tendencies to repetition in music itself. Our poetry, our ballads, our songs are full of repetition; nursery rhymes and the little chants and songs we use to teach young children have choruses and refrains. We are attracted to repetition, even as adults; we want the stimulus and the reward again and again, and in music we get it. Perhaps, therefore, we should not be surprised, should not complain if the balance sometimes shifts too far and our musical sensitivity becomes a vulnerability.

I was always the youngest boy in my class at high school. I have retained this feeling of being the youngest, even though now I am almost the oldest person I know.
