224 Shallow river under an open sky (sleep safe)

Night rain, as it falls onto a quiet suburban garden, has a cool and spacious sound-feel. It seems to help focus the mind's eye onto the presence of objects and surfaces that without the rain would simply not exist, to the ear. Even to the eye, in such murky darkness, these objects and surfaces are not things that make sense in and of themselves. This nocturnal suburban soundscape, stippled with falling droplets, reverberates with the ever-present ever wide city rumble. City rumble is not a warm nor a cold sound, and has no shape other than always to be the same shape. It's always there. Always present. Permeates every inch of outdoor space with a steady unchanging and strangely indeterminate aural glow. It has something to do with all the buildings. Something to do with all the distant machines that whirr and whine as we travel about, keep warm, keep cool, keep moving. Something to do with urban life. A little back garden in North East London is such an ordinary place from a soundscape perspective. There is nothing here to peek the interest in conventional terms. You'd probably never hear a place like this through any normal broadcast audio channel. And so the idea of a quiet soundscape, a quiet brutalist soundscape, made of layers of indeterminate aural glows, echoes of indeterminate activity, reverberances of empty spaces under a wide an empty sky, must make its indeterminate way to the edgeland of the audio world. And that is here. On Lento. A quiet brutalist soundscape from one rainy night in March.  

Back we go again to Miller's Dale in the Derbyshire hills. To this quiet spot, beside a shallow river wrilling. There's a country lane, and a steep grassy bank down to the river where an old tree grows. The tree, so gnarled, and with an unusually stout trunk, must have grown here for decades. Maybe even a century, or more.  At about five feet from the ground it split into two almost equally thick boughs from which winding branches reached out over the river. Covered in moss. Dense with summer leaves. Something had drawn us to this place. We climbed down because we wanted to hear how the river sounded from underneath the tree. It wasn't easy. We had to hold on to the trunk to stop us rolling down into the water. From underneath we found the leaves worked like a walled garden, cradling and reflecting the aural qualities of the swiftly moving water. It felt like a perfect place to sit and listen, so We felt around the moss and hung the Lento mics beneath one of the thick boughs and left it to record through the night. This section is from the dead of night. The river is flowing steadily. Steadily over the time worn rocks. Above the tree the open sky must have been thick with cloud. Almost all the wildlife is asleep, or making noise that is hidden by the sound of the water. Aeroplanes over fly from time to time, ploughing their nocturnal ways above the clouds from one civilisation to another. The English landscape, however rural looking, is very often aurally speaking not wilderness but edgeland. This is a real sound landscape that represents the world as it is. Whilst listening back to prepare this episode we heard tawny owls calling to each other, from far across the fields.  

Whilst walking up towards the observatory in the Kielder forest, we passed large areas of cleared woodland. "Fallen in the great storm of 2021" a passing forester explained in the afternoon sunshine. In some sections, the trees had been cut and stacked. Rows of tree trunks that smelled deliciously rich with the resin-y smell of Christmas trees. We found the smell instantly relaxing, as if it reduced blood pressure just by inhaling it.  We stopped on a steep rough path by a rushing burn, to take in the pristine quiet ambience. Banks of wind were brushing across the high tree tops. Grand firs, whose countless fine needles instantly convert wind energy into rich brown sound. The rushing water permeated the surrounding space with what we feel is the cleanest white noise mist we've come across this year. Capturing this sound scene was something we just had to do.  Finding a suitable tree for the Lento box by the path wasn't too difficult. Bathed in the white noise mist and the brown sound of the tall fir trees, we left the microphones alone to capture this passage of time. Slightly to the left of scene is the rushing burn. Fresh water speeding shallowly over steep flinty stones. High above and undulating from right to left of scene, wind brushes the upper tree tops, filling the air with waves of softly hushing sound. Various songbirds are singing, wrens and blackbirds but willow warblers seem to be very common in the Kielder Forest. Their song while quite fleeting is a lovely droopy descent down a simple scale of notes. It's very similar to the chaffinch song, only purer, and without the musical somersault that the chaffinsh seems to finish on.

In our quest to capture the pure sound of trees in true spatial quiet, we have without realising it, been following a long and winding path that has ultimately led us here. The Kielder Forest. It's a remote place for England. A place where the sound of trees can properly be felt and heard. A place where millions upon millions of trees grow together, across an area of 250 square miles (400 square kilometres).  Planning this recording trip involved OS Explorer map OL42. We also checked flight paths and road maps to try to guess what extent human made noise might filter into the forest. From the sparse few roads and giant area of uninhabited nothingness, the location looked on-paper like a very quiet place indeed. Ideal we hoped for capturing the real sound of trees, in high definition audio. When we say the 'real sound of trees', we mean the spatial sound of trees in an ever undulating wind. Wind that shifts in strength between soft to medium. Ideally with most variations around the 10 to 20 knot range and that peaks every now and then with slowly rising and slowly falling currents in the 25 to 30 knot range. For the spatial aspect, the trees need to be over a very wide area, and very tall. To be spruce and fir, because these make the sound-feel that we are most interested in. Evocative deep brown hushing.   Somewhat optimistic for these very particular conditions, we travelled up country and ventured deep into the forest. We found a location near the dam of Kielder Water, and in driving rain left the Lento box tied to a tree. Then returned to the village some way outside the forest to stay the night. It always feels strange to leave the box behind, alone in such a vast place. Now we are home and listening back, what it captured is magical to us. Here is the period of time from 3am to just before 4am when the majority of spring birds begin to sing in first light. The wind strengths aren't strong, but there is an undulating wind that can be clearly heard in the tall spruce and fir trees as the banks of wind move across this region of the forest. Echoes of owls can be heard too, distant geese and a strange barking which we can't quite identify. Delicate layers of bird song gradually begin to build as the time approaches 4am.  * As always with Lento listen with headphones or Airpods to properly hear the full range of aural qualities we strive to capture and share. 

Time to take in a view. A panorama that changes with the wind and the tide. It's about six o'clock in the morning, and the Lento box has been recording through the night, tied to a windswept tree facing directly out towards Looe Island and the English channel.   The scene has an aural horizon formed of disapated ocean breakers, crashing against rocks far below. Blended layers of panoramic undulating natural white, grey and brown noise. Close by, newly sprouted leaves flutter around the microphone box in fast currents of blustery air. As the gusts subside, a softer, calmer view of the headland is revealed.  There's a fresh bracing feel to this place. Spring birds sing and call. Land birds such as chaffinches, wrens, robins, chiffchaffs and wood pigeons. Some sea birds too, herring gulls and possibly some oyster catchers. It's an exposed location. Unsheltered from the elements blowing in from the vast and empty sea. Unsheltered, and so thoroughly enlivening.

West Looe at night. A Cornish town on the edge of the English Channel. An edge where human things end and emptiness begins. We've shared a few captured sound scenes from here over the last month. This is the one if you're searching for the sound-feel of long, true night quiet. What is true night quiet? Capturing rich and detailed audible quiet, in contrast to dead meaningless silence, is what we're always trying to do with Lento. By rich and detailed we mean those aural essences, those often very delicate sound signatures, that give a place its own sound feel, and that aren't actually created by anyone. The sound feel of a place is formed and shaped by what's in it, its geography and its weather.   On this part of the Cornish coast we found very little human made noise during the night. No aircraft overflying. Next to nothing on the roads. Just long stretches of time where the softness of the place's sound-feel can be experienced with clarity. This episode is a section of time from around 3am in early April. A blustery weather front was blowing in from the sea, billowing along the narrow lanes of West Looe, cuffing in the roof gaps, whistling somewhere in a distant chimney pot. Fresh. Very spatial. A true and uncluttered piece of time.  Here are our top tips about how to re-experience this captured quiet. Find a relatively peaceful spot and listen through headphones or airpods. If you have Apple Airpod Pros set the volume just over half way at about 60%. This closely matches the sound levels that would have been landing on your eardrums by actually being at the location. Volume levels do vary between headphones so we can't give reference levels for other types of ear phones. Having now tested decent noise cancellation we can say when it works it can be like turning the lights off to watch a film. Clean listening, largely free of extraneous noise. Nothing beats a quiet room with a comfortable couch though, if you have one, and a pair of velvet headphones. 

The time has come for hot sun. Hot sun and basking. Hot sun and basking, and listening to crickets. And just sitting, amongst the crickets taking it all in.  This sound scene is of the landscape around Arley station in Shropshire. Under high trees in full leaf. Golden fields as far as the eye can see, glowing in the afternoon sun. Farmland gold. And farmland birds. Bobbing crows. Wood pigeons. And a buzzard. Distant farm machinery working the land.  Distant children playing beyond the station. Distant echoes, that roll across the horizon from a departed steam train that can be heard in episode 187. Down the field there's a man working. Hammer and nails. Knock knock knock. From post to post he goes. Slowly repairing the fence that runs between the hedgerow and the railway line. Knock knock knock. And a rest. And a glance up, at the circling buzzard. No rush. It's hot. There's all the time in the world for this. 

It is hard to believe this is North East London at dawn. And yet it is. 5am, last Wednesday. Day break, on the 1st of May. Misted air, barely a breeze. Verdantly breathable air, filtered and cleaned by the dense surrounding woodland. When at 8am the park gates are unlocked, the people will come to walk the winding paths. Bathe in the atmosphere created by the trees. And breathe the restorative, country clean air.  This is what a nature reserve within a city does. It purifies the air, not just for the lungs but for the ears. Layers upon layers of veteran trees soften the city rumble whilst providing a myriad of roosting spots for the songbirds to sing. And as they sing, their mellifluous sounds echo and reflect off all the boughs, branches, and countless leaves, to form an aural brilliance that is wonderful to behold.  But behold the brilliance we rarely do. Rarely can do. 5am is not when most of us are around or want to be around. And perhaps, for the sake of the birds and their own sense of freedom in the trees that are their home, that's not such a bad thing. 5am is, shall we all agree, their time of day. Their chance to be on their own amongst their own kind. Be themselves, and be in the world, in their own particular way. Capturing an hour of this world, as it happened, and on a day when the sky was relatively free of planes and the nearby roads relatively free of traffic and sirens, is what the Lento box was there to do. Here is that hour of time, heard from behind the gates of the newly restored chapel at the heart of Abney Park nature reserve.   Our special thanks to Abney Park for allowing us to capture the dawn chorus from the chapel. We recorded this episode exactly three years after our last recording just before the major restoration project started in the chapel. Listen to the dawn chorus from inside the chapel in 2021, in episode 68. And more episodes from around Abney Park here.  

In winter gales amongst moorland trees at night. Dark sky. Empty of everything, except for the invisible moving wind.    A moor slopes steep up to the right. And half a mile of grassland slopes gently away down the valley, to the left. At the bottom, is a reservoir, hidden behind more trees. This grassy spot along a high gritstone wall, near an old iron gate, looks from the lane like any overgrown corner of a Peak District field. But it isn't. It isn't just any spot. It is a seat in an amphitheatre of specially arranged wind catching trees.  Of course nobody actually set out to specially arrange these outcrops of trees like this so they'd create such a perfectly balanced and spatially panoramic scene in winter gales. They only catch the wind and turn its energy into deep and richly undulating sound because that's what trees do. But having left the Lento box in this spot to capture this long passage of time, it feels wonderful to have discovered that this exists. Here it is. And the performance? An hour of fresh moorland air. 

You're not alone here, in this seaside town. A place of hot pasties, hot cups of tea, and families on a day out. A place of rolling Atlantic waves. This is East Looe on the coast of Cornwall. Thick grey sky. April cold. A sprinkling of rain, But shut your eyes, and it could be summer.  Find a good spot on the sand. You may need to move once or twice. Be guided by your ears. Then chuck your rucksack down, lean against it with your umbrella angled so its just behind, and you'll have the perfect spot for an uninterrupted cinematic sound-view of the crashing waves. In all their crisp textural detail. And spatial glory. Can you hear which way the longshore drift goes? Maybe not yet. It can take a few minutes. While you wait notice how there's an interesting mix of garden birds and sea birds here. A mistle thrush far left, or is it a blackbird? A wren too, far right. Beyond where the little children are playing. The waves feel powerful in this spot on the sand. Powerful, Sometimes thunderous. Coming, and going, in long swaying rhythms. Coming, and going, with wide spacious calm inbetween.
