Saturday, November 28, 2009Producer: CBC Radio 2Listen AgainOn this episode of The Nerve, host Jowi Taylor takes you on an aural journey, from the creation of sound at its source, through the air and the outer ear to the cochlea, the spinal column, and the cerebral cortex. On the way, you'll hear about how and why hearing evolved, and how the human ear is designed to react to certain sounds. Why do we hear some sounds as music, and other sounds as noise? What's the critical relationship between anticipation and satisfaction that drives music? Just what happens when the human brain and music become dance partners? And what roles do the elements we call rhythm, harmony, melody and timbre play in that dance?
