190 St Mary’s Church in Rye

We're hugely grateful to Revd Paul White of St Mary's church at Rye for enabling this special recording to be made.

An aural presence of St Mary's church. Captured through the night of the 3rd of October. This passage of time is as it happened, from midnight to 1am. Experience being in the nave, then perched high in the belfry looking down from the top ledge upon the bells, including the 'quarter boys' that strike the quarters. There's a wonderful old timber beam to rest against, so don't worry about the drop.

This sound-scene of St Mary's unfurls over an hour and between two slow alternating perspectives, each lasting about six minutes. It starts in the nave where the congregation gather for services and prayer. Then glides up to the belfry. 

Due to the extreme intensity of sound in the belfry (the sound of the main bell carries for miles) the sound scene during striking is from the perspective of the nave. On the very last strike, the perspective blends back up into the belfry, letting you witness the singing of the main bell as it fades away. (Note The clapper can be heard knocking slightly against the bell, as it settles back to rest after striking one.)

The church's clock marks each second passing with a crisp resonant clunk, as it has done for many centuries. Indeed it is one of the oldest church turret clocks in working order, first installed in 1561-2. The pendulum visible above the nave was added later. (Read more about St Mary's fascinating history.) 

The belfry is at the top of the church tower, and is a narrow space very much exposed to the elements. The clock's mechanism can be clearly heard from up here, together with the pressure of moving air as it presses through old rafters, and rocks heavy roof panels. To the right the flagpole outside vibrates against its sturdy mooring. The melodious strike of the quarter boys is close and clearly defined from up here inside the belfry.

In contrast the nave is a large spacious and sonically reflective space. High ceilings and wide stone floors. It's where the congregation gather for service. From here the main body of the church can be heard, shouldering the weather in soft, hushing reverberances. A peaceful place, for people, time and prayer. 

Please note that this is NOT a sleep safe episode due to the bell chimes and clock mechanism. It is a rare chance to hear such an ancient space at night with the sound of the clock inside and the wind raging outside. 

189 Night rain falls on a drystone wall (quiet and sleep safe)

There, thought the old drystone wall. I knew it. A tawny owl. Flying silent, up top the field. It'll only be a shadow, if ever you do get to see it. 

Better get to where you're going my feathered friend. The rain's coming. Not long, I'd give it, what, five minutes before the first shower.  A flurry. That's all. At least to start with. Night minutes mind. 

No! Night minutes aren't slower if that's what you're thinking. Nothing like that. No they're just, different. They don't run in a day-straight line. Night minutes spiral. Like the way currents on a slack stretch of river move. You know, in slow drifting circles. Sends your mind round in circles too if you let them.

They pass alright despite them going round in circles. Not sure how that works, it just does. All you have to do, to go along with them, is concentrate. Not concentrate on counting them. You do it by listening. All around wide about listening. Listening, without expecting or waiting for anything particular to happen. Do it by keeping your mind free of expectations and instead let whatever the world has for you, come to you, just when it does. 

Now call me an old drystone wall, which is what I am, but even I know half the problem these days is that when you set your mind on something you want to happen, you miss the simple pleasures the world has for you while you're waiting. No, it's not patience I'm meaning here. Why be patient. I'm not and I've stood sturdy here for centuries. It's diligence. An active process, of careful, and persistent listening to what is there. In the place you want to be.

* This sound view was recorded from the top of a drystone wall overlooking fields of nocturnal sheep, in the North Yorkshire market town of Settle last August. Rain comes and goes. It's a very ordinary field in many ways, and not far from a very ordinary sounding B road with some occasional night traffic on it. Combined with the odd soft arching plane, the sound view exudes a pleasantly harmonius aural fabric that is soporific and sleep safe.

188 Rock seat on Rye Harbour beach

Near a limpet covered wall, beaten into shape by high tide waves and squally weather, are some rocks submerged in shingle. Rye Harbour shingle.

Sun warmed, they've got just enough flat on top, for two to sit. And enough yards from the water too. For you not to get wet. And yet, from time to time, you do. But only a speck, thrown by an exuberant wave.

Advancing waves keep rolling in. Splashing and breaking, as much onto each other as they do onto the smart grey contoured shingle. Splashing and breaking waves whose sound is as bright as the light of the midday sun. From your smooth rock seat, you can hear the tide's not far now, from the turn. 

A tiny bead's landed upon the back of your knee-rested hand. One speck of cool ocean. You dab it away. Its translucent shadow feels like a winter penny in the brisk sea breeze. 

* We made this recording a few days ago on a warm October day at Rye Harbour beach in East Sussex. The sun was crisp and strong, as was the onshore breeze. One of the most wonderful feelings is scrunching over the different bands of shingle, as you head down to the shore, because of how the sound changes. 

** Thank you to everyone who supports us on Ko-fi.

187 Steam train stops at country station

You strode up to this field, through lush meadow, for a better view over Arley station. And now you're here. It's a perfect Shropshire August day. Blue sky. Light breezes. Hot sun on your back. Nearly time you think looking up into the sky, far right, for any sign of smoke. 
 
The whole station's in view from up here. Here beneath the tall whispering trees, and basking grass crickets. There's the empty waiting tracks, lined by high overgrown hedgerows. And a man down there. Hammer. Nails. Fence beside the gravelled track, being sporadically mended. Such a country scene. With such balmy country sounds. Benevolent. Timeless. There, watched by the circling buzzard. Chased away by rooks. 

And when it first came from over the horizon, it announced its imminent arrival with a blast on the whistle. Mile wide, its sound waves travelled. Through the cutting it then proceeded. To emerge like a resplendent surprise from under the old stone bridge. A heavily rolling, clanking, iron mass of hissing pressure, that gently squealed to a halt in the waiting station. 

As it waited for its passengers to board, it pressed against its wood block brakes, radiating heat. And a slowly building, smouldering hiss. And the whole valley seemed to brace itself for what it knew was about to come. The bridge and the sloping fields. The trees. The road. The buildings and even the sky. All braced themselves, to be turned inside out. Turned into a steam train dream. 
 
A steam locomotive, to give it it's proper title, does not so much depart a station, as leave it in its wake. Its iron furnace contains such pressure, that when its valves expose its pistons to pump the girders that turn the giant wheels, it's not just the air that's kneaded like a dough, but the whole world around it. It's a palpable sense of power that so surpasses anything you can have imagined, that all you can do is grin. Whilst fixed to the spot. In enchanted admiration. 

* We took this sound photograph of a steam train passing through Arley station last month. We recorded in high definition sound. After the train left, we left the box recording alone, to take in the soft rural wind in the trees, the crickets in the grass, the man mending the trackside fence, and all the other sounds of ordinary everyday life going on in this Shropshire valley.  

186 Slow forest Wyre valley

What happens, inside slow forest, is not much. Just the odd snap and crack, of a dry twig dropping, every now and then. 

I know sometimes there is a rook. And I know a raven too, if you've managed not to fall asleep. And echoes. Of passing people on the trail. And of seagulls and roosting wood pigeons too. Every now and then.  

No, not much happens, in slow forest. Apart from the wind in the trees. And the buzzing insects. And the distant farm. And the plaintive cries of what we might imagine is a lonely juvenile bird. 

But slow forest, is the place to go, if you want to hear a forest just being a forest. It's so huge. And so empty (not counting the trees) that most of what you hear is just, forest. Trees being trees. Leaves being leaves, in the changing wind. And the changing wind, just being a changing wind. 

* We captured this hour of forest time by leaving the Lento mics alone on an old tree last month deep in the Wyre Forest in Worcestershire. Two planes doing a loop-the-loop can be heard steeply descending around the middle section of the recording, and the echoing whistles of a passing steam train as it travels along the Severn Valley Railway can be heard towards the end. 

185 Onshore breeze on Chesil beach (sleep safe and in hi-def sound)

This onshore breeze. A pleasant one, will not cuff too much against your ears. It'll flutter. Like a dark brown feather quivers, on a current of moving air.

It'll be steady too. As a pleasant onshore breeze is. As the horizon is, from whence it came. Rising, at its centre. And falling away, almost imperceptibly either side of its farthest edges. A constant. And a consistent presence that lets your skin know just how endless the space is. Out there.  

A strange thing though. Worth noting. Worth remembering, for next time. How an onshore breeze is unchanging. While it comes from out there, from the wide open endless sea, and while it lands upon the shore just as the incoming waves do, it does no advancing or receding, like the waves do. No hauling back of the shingle. No pulling away making you feel your love is about to be lost only, seconds later, to be found again. No. Because with the onshore breeze, you always know where you are. It's constant. Cool yet convivial. Makes the time spent on the beach feel real. Right. Restorative. 

* We took this 30 minute sound photograph on Chesil Beach by Portland last April. Its the second take of the beach from a different location to episode 163 but taken shortly afterwards on the same day. Placing the Lento sound camera pointing directly out to sea, about fifteen yards from the breaking waves, the scene captures not only the steady on-shore breeze, but the deep visceral and spatial sound of the receding waves as they haul back huge quantities of the smooth, very heavy kind of shingle, that this section of Chesil Beach is made of.

184 River rilling through Miller’s Dale (sleep safe, hour-long)

Miller's Dale. Steep sided. A valley in the Derbyshire Dales with magnificent contours. High rocky outcrops. Sheer faced cliffs. Green fields plunging down to a quiet, winding river.  

It's a place where geologists go, to see the evidence of lava flows from millions of years ago. Where historians go, to marvel at Victorian viaducts and tunnels cut by hand in the 1800s. And where weekend people go to trek or cycle through open country along the disused railway lines that used to carry the trains between Manchester and London.

Miller's Dale feels cut off from the world. Alive in the moment, but somehow separated. As you wonder its winding and overgrown footpaths, you sense the valley is a place not only of restorative solitude, but a place where you are free to imagine yourself conscious in another time. Another era. Hearing the echoes of a rumbling steam train, chuffing northwards with Victorian haste. The meek baas of sheep, grazing on wet Iron Age pastures. Or the tide of the bygone sea, that the composition of the rocks shows this landscape almost unimaginably used to be.

Now the sound of water flowing is from the river. the River Wye. How steadily it runs, along the valley bottom. Open country water, that along the shallow stretches rills, pleasantly, over tumbled stones. Cool. Refreshing. Consistent. Rilling in watery melodies, if you let yourself listen for long enough.

* We left the Lento mics alone, hanging from a steeply leaning tree, to capture the spatial sound of the River Wye flowing through the night. Some planes are audible in the sky, possibly more than usual for 2am, due to a major air traffic control breakdown the night before.

183 Upland fir forest (sleep safe and ideal for headphones)

High, in the remoteness of the Cumbrian hills above Dentdale, with buzzards circling overhead, we found a fir forest. 
Tall, elegant trees, reaching up to the sky. 
All leaning, slightly, against a mild August breeze. 
The mild, long distance, cross country breeze.  

The hill was steep, so we stopped to take in the view behind. It was then we heard the forest. 
Its dense trees loomed above us. Only twenty yards away. 
Giant sails, in moving air. 
Tall. Dense. Each tree hushing not in white noise, but in noise of other shades 
Light browns. Dark browns. Dry stone greys. Twilight greens. Dark purples. 
Each undulating. And dissolving into the other. 

Nearby, we found a path. It led into the forest. 
Led into its quiet heart. 
Surrounded by hushing trees, we listened. Stock still. In total silence. 
A remote fir forest. High, in the Cumbrian hills. 

* We left the Lento mics alone to capture the undulating sound within the heart of this forest. At 29 mins a freight train can be very distantly heard as it rolls through Dent railway station farther down the moor. Or the fell, as the locals say. From ten mins in a buzzard can be heard circling directly overhead. Dentdale is at the western end of the Yorkshire Dales National Park.

182 Night scapes special - August intermission 4 (sleep safe)

For this last August intermission episode we've made you a montage of *sleep safe* sound-scenes selected from four overnight recordings.

From the sea wall at Burnham-on-Crouch, looking out over panoramic tidal estuary waters by Wallasea Island. An oak tree deep within the Forest of Dean where woodcock make their roding flights. A remote fishing village harbour under empty skies in South East Scotland. To a rural wood in Suffolk where we made our first ever overnight recording.

Here are some short descriptions plus links to the episodes so you can hear them in full.

126 The seawall and the night patrolling curlews
To be a remote seawall, on a stretch of tidal estuary. To see the days and nights not as periods of time, but as slowly undulating waves. To feel the weight of water, twice rising, twice falling. To hear, the lone patrolling curlews. This is Burnham-on-Crouch around 4am, looking out across the tidal waters towards Wallasea Island 

129 Pristine quiet to early dawn 
A clearing, deep within an expansive forest, where the night air carries so little sound that only the trickling stream can be heard. The stream's sound reflects narrowly off the trunk of the tree, like the flickering light of a campfire. But when a woodcock flies by, on its roding flight, the sense of space is temporarily revealed. This segment of overnight recording we made in the Forest of Dean. It begins at around 4am when the space around the oak tree holding the microphones is still pitch dark.

140 Fishing village harbour at night 
Real quiet from the middle of the night, captured from a point above the harbour of St Abbs on the East Coast of Scotland. Car-free. Plane-free. Just the sparse and spacious cries of circling gulls over harbour waves, and the faintest hum of a fishing vessel anchored somewhere out at sea. This remote, thousand-year-old fishing village is to us a place defined by its quiet horizons and empty, plane-less skies. 

74 Night shallowing in a Suffolk Wood
It's 3am in our first ever twelve hour overnight sound landscape recording. A Wood in Dedham Vale, Suffolk. Balmy August night. the Lento mics left alone to capture the sound landscape from deep within the uninhabited woodland. they revealed dark bush crickets, chirruping the passing of time. Wind moving softly over the tree tops. the distant bell of St Mary's church, floating through the space beneath the trees, striking three. Nocturnal animals treading lightly over dry leaves. This 2017 recording opened up a whole new world to us, and inspired us to make more recordings and share them through Radio Lento. 

181 Woodland scapes special - August intermission 3

For this penultimate intermission episode, we've made you a montage of sound-scenes selected from four enchanting woodland episodes. A forest ravine high in the Derbyshire hills. Under a tree above the town of Wooler, in Northumberland. A waterfall gorge on Dartmoor. And finally, the mysterious murmurings from deep within the Forest of Dean. 

Here are the descriptions and full episode links  so you can enjoy them in full.

160 Forest ravine
This precipitous place, high in the Derbyshire hills, flows with birdsong and fresh moorland water. It's aural presence is made almost entirely of natural things. Non-human, natural phenomena. Having this piece of time uninterrupted , and from this elevation, you can watch the geese through the trees as they fly through the ravine's luscious and airy reverberations. 

141 Soft land murmuring - Wooler, Northumberland
An exposed tree, looking down upon the town of Wooler, high in the Northumberland hills. It stands amidst wide open fields, by an empty bench and an overgrown footpath. The soundview of this wide panoramic landscape changes with the wind. Tawny treetop owls. Sheep. Cawing rooks. Flocks of chattering jackdaws. Wood pigeons, cooing comfortably from their lofty roosts. Then as the wind gathers strength, the soundview shifts to the interior space within the tree holding the microphones. 

162 Waterfall gorge on Dartmoor 
you've made it up, to the Dartmoor gorge. Thick untouched forest, and a rushing torrent, cascading down a rocky, precipitous gorge. Getting here, up and up, along a rocky path through endless trees, feels like a pilgrimage. A pilgrimage to a rarified place, that's lit through day and through night, by brilliant, refreshing, acoustic sunshine. (Since we took this sound photograph we've learned that regions of Woodland on Dartmoor have been designated as temperate rain forest.)

122 Forest bathing in the cathedral of trees
A passage of early evening time, captured by the Lento mics recording alone, from deep in the Forest of Dean. 
They hear wide spatial echoes. Woodland birds singing free of interference. Rich, layered murmurings. And air, moving gently through the high tree tops, of this ancient forest. We think of our sound recordings as sound photographs. Spatial sound scenes taken from one fixed position, over time. Our goal is to share the aural view of a place, in a spatial high detail way that lets you experience the true authentic feel of what it is really like to be there.  An aural reality of being somewhere else.

180 Coastal scapes special - August intermission 2

We're taking an intermission during August. Rather than disappearing, we're made you a montage of sound-feels selected from previous episodes. This week's theme is coastal.

Listen to four lovely clips of coastal scapes we've captured. Take a tour from Tenby in South Wales, Coldingham Sands in South East Scotland, and Nothe Fort on the Jurassic coast of England.

Here are the descriptions and full episode links  so you can enjoy them in full.

174 Where cool woodland meets the summer sea 
At the far end of the long sandy beach at Tenby there's an area of cool, shady woodland. From the distance and under hot summer sunshine, it looks idyllic. Inviting. Under the trees the hot sunshine air is cooler. Laden with sweet musty smells and sappy perfumes. The birds are singing. Their sound reflecting between the trees. Melding with the washing waves. 
This place is like a temperate greenhouse. A naturally reverberant space. Perfect, to set down, forget about doing anything, and just listen for a while. 

178 Waves of the intertidal zone 
It's late and you're out. in solitude, For an evening walk, on a wide open beach. Tenby beach in South Wales. Here, is white noise solitude. You scrunch over flat corrugated sand towards the shallowing waves. Then wade in. 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. 

150 Looking down on Coldingham Sands 
A bench. Perfectly perched, by the sandy steps that lead steeply down onto Coldingham Sands. Perfectly perched with a sound-view so wide, and angle just right, to hear the incoming waves as they break over outcrops of craggy, elephant-sized rocks. It's a bright August day, and the sun is mistily lighting up the sea, the rocky cliffs, and the plunging, richly vegetated slopes. This place, on the East Coast of Scotland, is special. It's a landscape under a genuinely quiet sky. A sky free of human-made noise, where the detail and quality of natural sound can reach the ear drums intact. 

176 Early morning below Nothe Fort
A smooth, sunrise sea, heard from a tree, growing up out of a bundle of boulders close to the water's edge. It's early April, and just after daybreak. The Lento kit is in the tree, capturing the wide spatial quiet of this place with nobody about, right beside Nothe Fort in Weymouth on the south coast of England. Ahead, looking south, the sea. West is Portland. East is Weymouth, then Durdle Door, near to Lulworth Cove. In this little settled spot, and from far left of scene, the sea seems to be breathing, softly, as it sweeps the shingle at the foot of the fort's huge parapet wall. Perhaps it's still asleep. Has it not heard the blackbird? Has it not heard the wren? Or the garden warbler? Maybe it hears them, from within a dream. 

179 Rain scapes special - August intermission 1 (sleep safe)

We're taking an intermission during August. Rather than disappearing, we're sharing a different type of episode, each with a theme, using some of the best bits from previous episodes. This week's theme is rain. 

Here are four glorious rain scapes. Travel with the rain as it falls, on a wide open coastal landscape, a walled garden in London, and on high moorland woods in Derbyshire.

Here are the descriptions and episode links  so you can listen to them in full. 

146 Fresh air along the Creel Path
The Creel Path has been trodden by fisherman on their way to work from Coldingham to the harbour at St Abbs in Scotland, for a thousand years. It's a landscape whose geography leaves it exposed to everything that the sky can bring. By locating our mics within the natural shelter of a tree, and letting them record alone for twelve hours, we were able to capture the full width, depth and range of this place and its unique soundscape. 

128 Persistent rain
Heavily, this winter rain falls. Persistent. Cold. Wet. Refreshing. In waves. In sprinkling flurries. Over time. Onto the huge tarpaulin stretched across the yard. Each drop's long downward journey is both completed, and revealed, in one tiny moment. Is this just plain old rain? Listen in, especially through a pair of headphones, and layer upon layer of spatially detailed rich textured sound will to you become revealed. 

167 An hour under moorland trees 
There is nothing and no one about.  You. Here. Hidden. Up in the Derbyshire hills. Sat, on dry leaf litter, lent against a gently slanted tree trunk. Listening. Just an hour. Under moorland trees. An hour to listen, to the weather, the flurries of rain And the steady ever-changing wind. 

156 Sheltered under night rain 
The city sleeps, under a dark impenetrable sky. In one garden, sheltered under a wide tarpaulin, microphones are recording. Alone. On top of a tripod, and standing, as high as a person. Listening. The tarpaulin, is to them a canvas. It lets them see the rain. In all its spatial detail. A transcriber. A taught thin surface, that catches each raindrop, and changes its collided imprint into crisp edged, spatial  sound.

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. 

177 Summer meadow woodland edge

You find yourself, suddenly out. On the other side of the wood.
The edge, of a wide open empty field. A meadow.
Tall elegant trees, given way to a high, bright sky. 

Standing silently. You can feel the heart of the forest behind you. Hear its echoes. Its leaves near and far, rustling. How one tree creaks. How banks of soft summer air move spatially across the treetops. How trains, passing distantly through the forest, make sound like silver wind. 

In front, is open grassland. Fragrant. Home to large populations of butterflies. And that sings, with the sound of stridulating crickets. Hundreds. Thousands. All cricketing, under this warm noon day sun. 

This meadow. These slowly swaying trees. This breeze, in the leaves and grasses. This feeling, of being so near to the cool green heart of this forest. And up, at the sky. And up, at the sun. And the shifting clouds. And the planes, flying from time to time. Flying, from cloud to cloud.

* We travelled into Hertfordshire (by train and on foot of course) to take this sound photograph from as near as possible to the Clinton Baker Pinetum one lunchtime last week. It's a fascinating place, rich for forest bathing, first planted in 1767. We want to take some more sound photographs that capture the range of tree species inside the pinetum if and when we can get permission.

176 Early morning below Nothe Fort

The sound-scene is of a smooth, sunrise sea, heard from a tree, growing up out of a bundle of boulders, close to the water's edge. It's early April, and just after daybreak. The Lento kit is in the tree, capturing the wide spatial quiet of this place with nobody about, right beside Nothe Fort in Weymouth on the south coast of England. Ahead, looking south, the sea. West is Portland. East is Weymouth, then Durdle Door, near to Lulworth Cove. 

Here, in this little settled spot, and from far left of scene, the sea seems to be breathing, softly, as it sweeps the shingle at the foot of the fort's huge parapet wall. Perhaps it's still asleep. Has it not heard the blackbird? Has it not heard the wren? Or the garden warbler? Maybe. In a dream.  

From right of scene, where the swell's near and breaking over the boulders, the sea's very much awake. Awake, and moving. Rising, falling. Gently washing the sunlit sharp rocks, in slow, circling motions.

High above, in wide circles, are the seagulls. Calling brightly to each other in the first light air. And some stray crows. And ducks. And something else. Something deep. Something that hums. It is, almost musical. Not animal. Or geomorphological. Too powerful, too omnipotent, for that. It's the kind of sound that isn't in the air. But is the air.

A ship. And its low humming engine. Moving. Very gradually. Across the horizon. Like a far drifting cloud.
