The power of music

With brains wired for song, we derive pleasure, feel less pain and transcend our body's limits

Dan Ellsey, 33, was sitting in his wheelchair in a soulless room at Tewksbury Hospital, his virtually useless arms and weak torso strapped to the chair for safety.

Suddenly, as soon as we were introduced, he arched his back, grinned broadly, and aimed the riveting power of his dark brown eyes at me, as if eye contact were his only means of transcending the prison of his body.

But it isn't. In the last few years, Ellsey, who was born with cerebral palsy, has discovered another, almost miraculous, way of expressing himself: music. Not just listening to country and soft rock, as he has done for years, but composing music himself with a special computerized system called Hyperscore, developed by composer-inventor, Tod Machover, professor of music and media and director of the Opera of the Future group at the MIT Media Lab.

I stand there, awed, as we listen to Ellsey's music, which on the computer has an abstract, eerie sound that swells and recedes like ocean waves. As we listen, we watch on the computer screen as the "score" - colored lines on a graph that represent different instruments - unfolds before our eyes.

A look of pure bliss crossed his face. For Ellsey, as for most human beings, music has almost inexplicable power - to rouse armies to battle, to soothe babies, to communicate peaks of joy and depths of sorrow that mere words cannot.

Just why evolution would have endowed our brains with the neural machinery to make music is a mystery.

"It's unclear why humans are so uniquely sensitive to music - certainly music shares many features with spoken language, and our brains are particularly developed to process the rapid tones and segments of sound that are common to both," said Dr. Oliver Sacks, the neurologist whose latest book, "Musicophilia," is about the brain's sensitivity to music. Some researchers, he added in an e-mail interview, believe that in primitive cultures, music and speech were not distinct. Other researchers debate which came first in evolution, speech or song.

What is clear is that the brain is abundantly wired to process music.
