Purcell's magnum opus was written as a series of masques to be performed at the end of the acts of a special version of Shakespeare's A Midsummer Night's Dream. Arguably the greatest British composer before the 20th century, Purcell left us a tantalizing array of music for use in theatrical productions, which shows what an unsurpassed gift he had for matchings words and mood with music. Apart from the small-scale masterpiece, Dido and Aeneas, none of these pieces quite hangs together as a satisfying work of music theatre. The Fairy Queen is the closest we have to that. Written in a hybrid form of spoken drama and masque, it is notoriously difficult to bring off on the stage. But it is ideal for home listening.
