Mozart’s Requiem and

THE VIRTUES OF FRANZ XAVIER SÜSSMAYR

X¯ Listen

 

The story of how Mozart came to compose the Requiem has often been told – in fact and in fiction. The mysterious man in grey who commissioned it from him for a generous fee but under the condition of secrecy, turned out to be the servant of a Count Walsegg who intended to claim the work as his own at a memorial service for his wife. But Mozart only lived to complete the vocal parts and the figured bass up to the end of the "Hostias" (except for the "Lacrimosa" after bar 8), the complete orchestration of the "Introitus," the first violin part of the "Dies irae" and "Rex tremendae," and otherwise only sparse indications here and there, such as the trombone solo which opens the "Tuba mirum."

 

The various types of handwriting in the autograph and in the surviving copies indicate who contributed to the completion of the work. The "Kyrie" seems to have been filled out during Mozart's lifetime: here the mechanical task of writing the string parts, which stick to the vocal lines, was performed by his young pupil Franz Jacob Freystädtler and the slightly more skilled work of writing the trumpet and timpani parts was done by Franz Xaver Süssmayr.

 

After her husband's death Constanze Mozart asked Joseph Eybler to complete the Requiem. He finished the orchestration up to the point in the "Lacrimosa" where Mozart had laid down his pen forever, where it became necessary to compose rather than just to orchestrate. Eybler wrote two very unconvincing bars of melody in the soprano part and then gave up the attempt, handing all the material back to Constanze. On the evidence of an early copy, which preceded Süssmayr's work, she next approached Maximilian Stadler, who orchestrated the two movements of the “Offertorium."

 

At last she entrusted the task to Süssmayr. He had been with Mozart for most of 1791, except when assigned to look after Constanze, when she stayed in Baden for the sake of her health. He had done various jobs for Mozart, including copying out the singers' parts for "Die Zauberflöte (the magic flute)" and probably composing the recitatives for "La clemenza di Tito." He also later recalled that during the last weeks "he had often played and sung the completed parts through with Mozart, who had very often discussed with him the completion of the work and the course of his instrumentation with his reasons." Constanze later told the publishers Breitkopf und Härtel that Mozart had instructed Süssmayr to complete the Requiem, in case he himself would not live to do so, by using the first Fugue again at the end.

 

The real mystery about the story of the Requiem is – why did Constanze call Süssmayr

in only as a last resort, when he had been closest to the dying composer and the only one

who knew his intentions for the work? She herself wrote many years later: "The reason I

gave it to Eybler to complete was because I was angry with Süssmayr (I do not know why)

and Mozart had had a high opinion of Eybler.”
