Maggie Koerth-Baker has an interesting entry on Boing Boing today on the biology of music and why humans like specific groups of tones. Her post discusses a recently published paper by Duke's Dale Purves, PhD, and Kamraan Gill, PhD.
The sounds humans make matter most, he said, because that's where we get information about our competitors and our potential mates--the things we need to know to be successful creatures. We developed an ear for the tones common in human vocalizations, the same way a sommelier might develop a taste for fine wines. Those are the tones we find most appealing and thus, the ones we made into our musical art.
