In this series of The Essay, recorded this week in front of an audience at Hay Festival, five writers explore The Art of Storytelling. The writers include artist and memoirist Edmund de Waal, broadcaster and musician Clemency Burton-Hill, Shakespeare scholar Professor Emma Smith and novelist Jon Gower.

Today, with so many of the world's languages disappearing, Professor David Crystal asks how we can preserve for the future the many different stories of accent, dialect and language.

Part of Radio 3's week-long residency at Hay Festival, with programmes In Tune, Lunchtime Concert, Free Thinking and The Verb all broadcasting from the Festival.
