We are what we hear?

I don't think so. But we can be what we heard in the past, or what we have heard throughout our lives. According to Laurens Rademakers, from Brussels - Belgium (see: http://www.ted.com/profiles/114581):

"This is a profound mystery which I cannot begin to ponder. Perhaps you can help?

Think of it: technically speaking, music is just a collection of sounds interspersed by silence.

But every human being knows of pieces of music that really "touch" him or her emotionally. These emotions can be very strong, and transport you to another "place".

How is it possible that a mere collection of sounds gets associated in our brain with memories, experiences, emotions, stories, images, feelings...? Why can we even cry when hearing a particular piece of music or even a fleeting, short succession of a few notes?"
