Alessandro Scarlatti's St John Passion was the first Passion setting written in seventeenth-century Italy. Scarlatti treats the role of the Evangelist (composed in the mezzo-soprano register) in highly unusual fashion, giving his narrative numerous emotional passages. The Voice of Christ (bass) is invariably haloed by a string accompaniment. The version presented by Leonardo Garc�a Alarc�n inserts meditations assigned to the chorus; these are taken from Scarlatti's Responsories for Holy Week, polyphonic settings that reveal a little-known genre practiced by this composer.
