The making of this high-definition sound photograph of Chesil Beach began thanks to the number 1 bus from Weymouth to Portland. As we stepped aboard, the sky felt low. Folded and layered with grey October cloud. Rain was in the forecast so we'd taken raincoats. 

After twenty minutes and the final stretch across the exposed coastal road, the bus pulled into our stop. On the way the views of Portland had struck an impressive sight, pointed bravely out to sea. It felt blowy off the bus as it always does here, but no rain, yet. We crossed the road, then up and over the largest shingle berm of any coastal area we know.

Dropping down more berms, scrunching over more acres of perfectly rounded pebbles, we and the Lento box finally arrived at the shoreline. Here is a soundscape that's beyond description. It takes a few minutes to acclimatise. Aural textures and flows wash around and through us, folding and layering like the clouds above. We'd forgotten how everything about this place engages the senses. Redefines what's normal. Resizes us into what we are. Tiny individuals, standing upon billions of even tinier stones.

The rain never came. Instead windows of blue opened and closed between the folds above. As the mics captured the scene The onshore breeze remained steady, letting the Lento box record every spatial and textural detail of the Chesil waves, only light winds buffeting.

The sea glowed turquois blue against the ruffled grey sky. Each rolling wave then turned pure white, as it broke over the beach of rich brown pebbles. The shore here stretches as far as the eye can see. To left of scene. To right of scene. Turquois. White. Brown. A unique place, with a unique soundscape, crystal clear, free of interfering noise thanks to the giant shingle berm.

* We made this on-location recording on Chesil Beach in Dorset just after 1pm on Wednesday this week. Special thanks to our friends and Lento supporters who live in Weymouth. They gave us a lovely welcome and a warm tea stop on our travels to make this recording. We feel it's one of the best sound captures we've made so far of Chesil Beach. further segments to follow in future episodes from this same location.
