Relax with a calming mix of music and natural sounds, from birdsong and tortoises in the Seychelles to waves and whistling frogs in Barbados, via a bubbling brook in Northumberland and a murmuration of starlings playing in a poplar tree. Recordings by David Fay, Honey Schreker, Kathryn Potts and Rupert Ormond.

High in the mountains snow falls. As it comes to rest on the frozen slopes it become part of an ancient glacier. Over the course of 100 years the glacier will flow down the valley, changing the landscape around it.Using field recordings from deep within glaciers, along with the sounds of the natural world around them, this programme charts an imagined journey of snow and glacier from mountain top to valley floor.Over the course of that journey we hear the sound world change and the increasing impact of human activity on the landscape - the wilderness of the high slopes replaced by the noise of tourism and traffic. There is an irony to the fact that the people who choose to visit the mountains because they love them are also contributing to their changing environment.These unique glacier recordings have been made by Ugo Nanni, researcher at the University of Oslo who specialises in the stability of Arctic glaciers, and field recordist Clovis Tisserand.Producer: Barnaby Gordon

It is January 2022, and in the Upper Manhattan neighbourhood of Harlem all is quiet as people stay at home, preferring not to venture out into the minus-13-degree snow and ice that has blanketed the city.This half-hour soundscape begins with the geese pecking at the frozen lake at the northern tip of Central Park with the occasional sound of a passer by who has braved the weather.As we head north to Harlem, walking up Malcolm X Boulevard, an invitation into the warmth of the Abyssinian Baptist Church is welcome. It is no ordinary service but a celebration of Martin Luther King Jr and we hear sounds of the pastor and gospel choir as they join together in worship.Heading back out into the bracing cold, Harlem is busier. More people are gathered on the streets with stereos playing music, and public transport still in operation, battling against the snow.Sounds of live jazz emerge from local restaurants and wandering inside is a refuge from the weather, joining crowds of brunch-goers enjoying live music, drinks, food and the company of others.It takes about half an hour to walk from Central Park to the Jackie Robinson Park, where a flight of swallows can be heard returning us to the sounds of nature that we heard at the beginning of our walk.
