Johann Sebastian Bach was 30 when he became head of music in Anhalt-Cöthen, in what is now Germany. Here he started an uncharted experiment in classical music: solo works for string instruments.
Johann Sebastian Bach’s The Art of Fugue is a work of high art. But in keeping with the late works of artists such as Shakespeare, Beethoven and Goya, it contains elements of pathos, humour, gravity, exuberance and tragedy.
