Did you know that the swish of a golf club is a musical learning experience? A walk in the Necklace Park could be music to someone's ears.

Professor decodes life note by note

"Much as people thump a watermelon to test its ripeness, Stanford composer Jonathan Berger wants them to use sound in novel ways to figure out the world. So he put sound to the way professional golfers swing their clubs. The result: It's now possible for pros and duffers alike to improve their game by listening to their own strokes. In another experiment, runners, rowers and other athletes can "hear" how their bodies are performing -- from heart rates to stress levels -- while practicing. And Berger's sounds for digital images of microscopic cells can help doctors distinguish cancerous ones by the "music" they make."

You know how it is. Out & about with your tunes, one of which is your perfect soundtrack for some activity, whether it's gliding through the arcade at Millburngate or trail surfing under the Elvet. So here's the challenge: You're somewhere in the Necklace Park; you're doing a particular thing, running or walking, maybe with a camera, a book, your bike. Now: what melody is going through your head?

Come back here and tell us what, where, when. Can we make an audio map of the Necklace Park?

Or the other way round. Can we make a journey that involves going to a particular place and listening, then describing what we've heard? What do you hear when you put your ear next to the stones around the marketplace?
