178 Waves of the intertidal zone (Don’t forget Lento’s built for headphones!)

A shadow grey rock, the size of a stranded ship. Radiating heat, remembered from the midday sun. Around it, rock pools, and smooth curving shapes. Like sleeping seals. You're out. Alone. For a late evening walk. Overhead, and behind, the sky is a deep, deepening blue. An end-of-day blue. But to your right, on the low west horizon, it's still blazing bright.

This place, this wide open beach, is white noise solitude. All around, empty space. Empty space and sea air breezes. Sea air breezes, and some people. Happy cries, and beach ball thumps.

You walk. Scrunch sand between your toes. You swing your legs towards the sea. Head towards the intertidal zone. Stepping on hard ruttled sand. Over furrows of stranded water. For as far as the eye can see. Corrugated land. Low tide land. Shaped into longitudinal lines by the withdrawing waves.

Right ahead, bright white noise. And gulls. Just landed on the wetted sand. Rapidly stamping their little webbed feet, to bring up the morsels. A rush. Of cold fizzing sparkling rippling water. Breaks suddenly over your feet. Breaks, and splashes up your ankles. Stops you in your tracks. Swirls and foams and flattens and shallows, all around you. Fills the air with watery sound. Like shimmering blue, shoreline silk.

Now you're in, and immersed. Ankle deep and paddling. White noise is everywhere. Waves, are everywhere. Racing. Washing over each other. Left to right. Right to left. Face on. And under. Rushing away, behind you. Tiny bubbles. Sparkling. Shallowing. And dissolving, into fizz. Each one, each wave, adding one more corrugation, on the wide intertidal sand.

* This sound photograph of Tenby beach is first try of something new for Lento. We recorded it dynamically, as we walked, in one unbroken 30 minute take. Angling and panning the Lento kit, holding still on wide panoramic views, then panning down almost to touch the water for close-up views of the sparkling bubbles, then gently sliding sideways to chase waves as they race to the shore, as with a film camera. We wanted it to be a kind of sound film.

If you can't make it to the beach this month we hope you can enjoy this intertidal sound walk, until you can.
