Sheltered against the gnarled trunk of an old holly tree, beside a country lane, the microphones are recording. Or maybe to them, they are looking. Looking out, as they have done for hours, at this mild valley, in sound. 

From this tree, the valley stretches far and wide. In front is a wide field. It slopes gently down and meets a stony rushing stream. Beyond, and up again across another field, is a farmhouse, partly hidden beneath tall winter worn trees. To the left of the scene, the stream passes into a ravine. Its steep sides reflect and amplify the soft white noise of the flowing water. To the right, animals graze on upland pastures. 

Here, is up in the Derbyshire hills. A place, that to us city dwellers, may feel like a place to retreat. But this is not all that it is. By visiting it, even through headphones and a bit of time, the meaning of this landscape can be observed, read and understood. The patterns of the wind in the tree. The ways the birds communicate, come and go. The distant murmurs of animals. Things that are heard best, when there is no human presence to interfere. This segment ends with the panoramic sound of passing geese as they fly along the course of the stream to reach the reservoir beyond, where they spend the day.
