Isaac Newton's 'Truth is ever to be found in simplicity...' has often been echoed in music by many of the great composers down the ages. But during the 20th and 21st centuries, akin to movements in the visual arts, some composers have pared down their music to a few seemingly basic elements. But how difficult is it to achieve meaningful musical simplicity and what's the difference between that and mind-numbingly banal simple-is-as-simple-does?

With the help of composer Howard Skempton and Tate Modern curator Emma Lewis, Tom Service discovers the hard and often complex truths about simplicity.
