1. Choose a landscape. It may be one you like, or it may be chosen by chance, or it may simply be a convenient one. You may wish to have a few walks or trips out in the car to decide. When you have chosen it find it on an Ordnance Survey Map.
2. Draw a straight line on your map, connecting two points.
3. Go for a walk along your straight line. Take a compass. If you encounter obstacles find a way round them, through them, under them, over them. As you go listen for any sounds you can hear. Sometimes stop and close your eyes. Try to imagine what sounds you would like to associate with this landscape. Are they electronic, synthesised, entirely natural, conventional musical instruments, instruments you may have to invent? Are they sounds that haven’t been invented yet? Make notes if necessary.
