Stephen Johnson considers Robert Levin's recompletion of Mozart's Requiem and its relationship to the version made by Mozart's pupil, Franz Sussmayr.
It's not possible to know precisely what Mozart's plans were for the Requiem he left incomplete on his death in 1791. At the request of his widow, Constanze, a completion was made by the composer's pupil Franz Süssmayr but lack of physical evidence means its proximity to Mozart's intentions cannot be proved. Two hundred years after the first completion, the musicologist, academic and performer Robert Levin recompleted the Requiem, aiming to enhance Süssmayr's version rather than replace it. Stephen Johnson examines the relationship between the two versions.
