Downtown Nashville, Tennessee

Think of the American South and one man-made sound plays out evocatively across the landscape: the horn of a passing freight train. For a century and a half it's been almost synonymous with the idea of America, particularly where the rural blends with the urban. In the city of Nashville, Tennessee - 'music city' - the last century has been accompanied by another signature sound: the honky tonk bar.

In this leisurely half hour, we witness the musical arrival of a freight train as it crosses the public highway into downtown Nashville. The rattle of the tracks and sonorous horn dissolve into the sounds of Broadway, the strip where every premises has windows open onto the street, spilling music out to draw tourists in. And between the bars, buskers plug the gaps.

It takes about half an hour to walk up and down Broadway from the Cumberland River - past honky tonks throbbing with Dolly Parton and Lynyrd Skynyrd covers, street renditions of Louis's Wonderful World and pedal-powered bars pumping out hits for bachelorette parties.

The sounds which compete for our attention within this cacophony provide as vivid a snapshot of contemporary Nashville as the freight train horn that sits so snugly within this cityscape, framing the downtown walk.
