In 2017, audio producer Phil Smith travelled to Ukraine to attend his friend's wedding. There, somewhere between the cities of Ivano-Frankivsk, Lviv and Odessa, he fell in love with the soundworld of the sleeper train: its steady hypnotic rhythms, the melody of hurtling through time and space, the calls of distant tannoy speakers drifting across platforms in the dead of night, the chorus of snores from sleeping passengers. Revisiting these recordings, seven years later, this Slow Radio journey offers echoes of a country in calmer times, when such trains were not a means of logistics transportation or symbol of desperate escape (as witnessed in the February of 2022) but conduits of restful imagining.

From the opening establishing shot - the sound of whistles and shunting engines, off in the distance - we are moved along in a river of wheeled luggage through the cathedral acoustics of a station building to take our seat in the carriage of the overnight train. The scenes are unhurried as bunks are unfolded and brief snatches of conversation overheard. We set off - a gentle accelerando of wheels and rails - and time stretches: there are no voices now, just the music of the train's motion through the night.

From the medina of Marrakech to the palmeries in Zagora, join sound recordists Andrea Campisi and Silvia Malnati as they embark upon a roadtrip in sound, leaving the capital city to journey across southeast Morocco. Across four movements of contrasting energies, bound together by the motif of the muezzin’s call to prayer, we listen to an immersive musical suite comprising binaural field recordings and on-location sound.

I. Allegro: In Marrakech medina we take a walk through a maze of streets and stalls before arriving out onto the iconic Jemaa el-Fnaa square. Here, we’re met with the hypnotising sound of pungi flutes and, as the sun sets, of gnawa musicians, jesters and Said Anazoure’s intricate banjo playing.

II. Largo: We leave the city behind to seek refuge in the mountainous region of Ourika. Here, we hear sounds of village life, as well as the distant voices of children reciting the Koran from behind the school’s door.

III. Scherzo: Having crossed the Atlas mountains, we descend towards the Draa Valley and its oasis, tuning in to the sound of the palmeries just outside Zagora. As night falls, crickets take their place alongside the mating calls of cats under the stars.

IV. Finale: We resume our drive, headed for a village outside Aït Benhaddou. A local family invites us to spend the night inside their tigmi, a traditional house, and attend an Ahwach ceremony with the musicians of Ahwach Asfalou.

With special thanks to Hamid Boukhch, Said Anazoure, Ahwach Asfalou (Mme Ijja, Hiba, Iken, Oumaghlif, Bendrisse, Hanafi, Ait houssa, Tabrahimte, Belmadan, Mr Haji, Mr Ifliisse, Almsalla, Belaabass, Benhdouch, Boularia, Ait Bikouch, Khalfi) and Alexa Kruger.

Relax with a mix of music and natural sounds, recorded by Radio 3 Sunday Breakfast listeners. Three dawn choruses from across the UK, starring woodland, garden and sea birds, follow on from the very different dusk chorus from the remote Greeenland town of Ilulissat, which features hundreds of huskies. Recordings made by Julie Moody, Alice Smith, Ted Reed and Michael Bawtree.

Time unravels in this hypnotic audio journey...

In this edition of Slow Radio, we tumble inside the delicate mechanism of the clock - our attempt to contain and mark the steady rush of time itself. Musical and rhythmic, this surreal audio composition moves between the meditative beat of a single timepiece through to a cacophonous eruption of melodious chimes and cuckoos. The Clock will air just after Big Ben's midnight chimes play out on the BBC, 100 years after London's most famous clock was first broadcast on New Year's Eve 1923.

Featuring audio first recorded for the documentary Time Flies on BBC Radio 4, as well as new recordings and compositions built from the sounds of Big Ben's internal mechanism and ringing bells.

How does the Berlin urban landscape sound?

Using a unique approach that combines field recordings and photographs translated into audio, the Uruguayan and Berlin-based artist Darío Dornel, aka Kirap, takes listeners on a captivating journey through the city's hidden soundscapes.

Pictures of recognisable city places are translated into sound using audio software through Bitmap's code conversion. A wide range of sounds is generated using various sound design tools and techniques. These sounds are combined with field recordings from the same places, creating an immersive sound exploration trip.

The journey starts at an old Berlin district, where listeners are greeted by the songs of birds, we then explore a street market in Neukölln, a demonstration on the old Prussian road, to finally listening to the day fading out at a train station, and welcoming the night at a known corner in Mitte.

Whether you are a local or a first-time visitor, this sound piece offers a fresh perspective on Berlin's urban landscape and a new way to experience the city by uncovering hidden features initially unnoticed. Take advantage of this chance to imaginatively travel to Berlin and discover the sonic landscape that makes this city unique.

Relax with a mix of music and natural sounds, recorded by Radio 3 Sunday Breakfast listeners. We start in the Himalayas and end in an urban forest in Dehli, getting there via Kardamyli beach in Greece and the Thames footpath in Oxfordshire. Recordings made by Naryndra Kumar, James Hadley, Kate Sandars and Michael Lidgley.

YA Z AN, a Palestinian Berlin-based artist, travels around his hometown of Ramallah, located in the heart of the West Bank. During his journey, YA Z AN encounters sounds that comfort and remind him of home. He uses binaural technology to collect audio pieces from the verdant Palestinian landscape and sculpts them with sounds from everyday life to create a complete surround sound experience.

Setting off with a ‘oud player singing folklore music during a post-wedding ceremony and followed by a walk to home where family is gathered at a dinner table chit-chatting about food and how it is prepared, the recent events that resulted in the death of martyrs in Palestine and the earthquake that occurred in Syria/Turkey. Progressing through the day, Yazan goes down to the city centre farmers market (Al-hisbeh) where a number of street vendors are shouting out the prices of their products.

Upon joining friends to hangout, the journey travels further to a jam session when surprisingly the rhythm of the community turns into a small choir.

The journey ends with Sufi singer Shadi Al-ahmad intoning his voice in his historical Palestinian home with a cross vault ceiling that accents his baritone.

With its peak at 2410 metres in altitude, the North Grigna is an imposing quasi-mythical character in the local culture of the Lombardy region. Those who get to its top can take in a 360-degree view over the Alps, Lake Como and the plains around Milan. Celebrated by Leonardo Da Vinci in his Codex Atlanticus for its rocky ridges, the mountain is also the protagonist in an Italian Alpine folk song entitled The Legend of the Grigna. The lyrics speak of a beautiful female warrior who is turned into a dangerous mountain, divine punishment for her having asked a sentry to fire an arrow at her suitor.

This song - sung in Italian by a local choir - frames our ascent on foot to the top of the North Grigna. As the singers recount the story of the warrior, warning us of the dangers of the hike, we pass through woodlands of beech and larch trees, and encounter small pastures where sheep and donkeys graze. There are rain showers, steep slopes, scree and snowy paths to battle and rare encounters with other intrepid Alpinists. The target is the Rifugio Brioschi, a wooden hut at the peak of the mountain where fellow hikers raise a glass and share tales from the climb before turning in for the night.

With special thanks to the Coro Grigna for allowing us to attend their weekly rehearsal and record La Leggenda della Grigna, and to fellow hikers Hannah Mackaness, Monica Malberti and Valentina Rossini.

Relax with a calming mix of music and natural sounds, from rooks on Orkney to a midwife toad chirruping in south-west France. Plus bats in Lancashire and nightingales in Sussex. Recordings by BBC Radio 3 Sunday Breakfast listeners Stephanie Fritchley, Aidan Semmens, Simon Tuck and Paul Richens.

Beekeeper Anthony Smith looks after several hundred beehives across Herefordshire and South East Wales. This episode of Slow Radio takes us to one of his apiaries where we eavesdrop on Anthony’s activities. It’s the middle of the summer, and the bees are at their busiest.

Many of the sounds of bees and beekeeping have barely changed for thousands of years, whereas others are distinctly modern. We’ll hear single bees collecting nectar as they move from flower to flower, and clusters of bees jostling against each other inside a busy hive. The beekeeper releases puffs of smoke to calm his bees as he inspects their work and we can hear the subtle differences in buzzing between a colony with or without a queen.

Over in the workshop, or ‘honey room’, we witness the processes that transform a frame of honeycomb into a pot of honey, from the spinning of the frames to the filling of the jars.
