Like the great French revolutionaries, Beethoven was convinced that he was writing for posterity. When (as frequently happened) musicians complained that they could not play his music because it was too difficult, he used to answer: "Don't worry, this is music for the future."

If any composer deserves the name of revolutionary it is Beethoven. He carried through what was probably the greatest single revolution in modern music and changed the way music was composed and listened to. This is music that does not calm, but shocks and disturbs. Alan Woods describes how the world into which Beethoven was born was a world in turmoil, a world in transition, a world of wars, revolution and counter-revolution: a world like our own world.

Last week, Arthur Miller, the dramatist who wrote plays that dealt with big moral and political questions in America, died. The legendary playwright, who continued his commitment to art and politics until the end of his life, was 89.

Phil Mitchinson reviews a new book Remembering Arthur Miller and interviews one of the contributors, the well known director David Thacker who worked with the American playwright on numerous occasions and was the artistic director of the famous Young Vic theatre in London. Miller's courageous stand against McCarthyism is well known but perhaps less generally recognised is how important an influence politics in general played in his life and writings.
