Music originally had a social function. You were in church, in a concert hall, a marching band; you were dancing. I'm concerned that music could be too separated from its roots and just become a pleasure-giving experience, like a drug.

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.

Music can move us to the heights or depths of emotion. It can persuade us to buy something, or remind us of our first date. It can lift us out of depression when nothing else can. It can get us dancing to its beat. But the power of music goes much, much further. Indeed, music occupies more areas of our brain than language does-humans are a musical species.
