Curated by Mark Fell and Joe Gilmore. Narrated by Connie Treanor.

The third episode in the series examines the use of determinacy and indeterminacy in music. It looks at how chance has been used in a variety of ways in the composition and performance of musical works – from works derived from the tossing of coins, to more rigorous explorations of the laws governing probability. The programme also looks at the use of chance in the visual arts and literature, and changing approaches to science during the twentieth century, describing the impact of these disciplines upon music making.

It investigates concepts and ideas behind these works with reference to works drawn from different traditions.
