Dances for the balls
As court chamber composer Mozart writes minuets, German dances and contredanses for the balls in the Redoutensaal. This is his official job, the one the court pays for.

A post at St. Stephen's
The city council appoints him unpaid assistant to the cathedral Kapellmeister, with the right to succeed him. A steady church post he had long wanted.

Constanze leaves for Baden
Pregnant, Constanze goes to take the waters. Mozart stays in Vienna to work on The Magic Flute and writes to her almost daily. Most of this year's letters come from here.
'Out of sheer boredom'
Out of sheer boredom I composed an aria for the opera today.
The opera is The Magic Flute.
Ave verum corpus
Forty-six bars for choir, written in Baden for the local choirmaster Anton Stoll for the feast of Corpus Christi. One of his simplest and best-known works.

Süssmayr is already around
Tell Süssmayr, that silly fellow, to send me the score of the first act, from the introduction to the finale, so that I can orchestrate it.
Franz Xaver Süssmayr, pupil and assistant, will be finishing the Requiem within six months. The tone is domestic, almost familial.
La clemenza di Tito commissioned
Prague orders an opera for the coronation of Leopold II as King of Bohemia. The deadline is a few weeks. The recitatives, by tradition, will be written by Süssmayr.
The Requiem commissioned
The anonymous patron's intermediary brings a letter and an advance. The exact date is unknown; by later accounts it happened in the summer, before the trip to Prague.
A son is born
Constanze gives birth to Franz Xaver Wolfgang, the sixth child. Two will survive: he and Carl Thomas.
August1 ·
Departure for Prague
Mozart, Constanze and Süssmayr travel to the coronation festivities. He finishes Tito on the road and on the spot.
September2 ·
Premiere of La clemenza di Tito
On coronation day, at the Estates Theatre in Prague. The empress, so the story goes, called it 'German rubbish'. The public took it better.
Premiere of The Magic Flute
The Theater auf der Wieden, outside the city walls, Schikaneder's company. Mozart conducts the first performances. He finished the overture and the March of the Priests two days earlier.

'The silent approval'
I have just come back from the opera. It was as full as ever. But what pleases me most is the silent approval. You can see how this opera is gaining ground. And now I have orchestrated almost all of the rondo for Stadler.
The opera is The Magic Flute; the rondo is the finale of the Clarinet Concerto.
The glockenspiel joke
During Papageno's aria with the glockenspiel I went behind the scenes, as I felt like playing it myself. For a joke, when Schikaneder paused, I played an arpeggio. He was startled, looked into the wings and saw me.
The eleventh performance of The Magic Flute. Schikaneder was playing Papageno.
Salieri at the theatre
Salieri listened and watched with the greatest attention, and from the overture to the last chorus there was not a single number that did not draw a bravo or bello from him.
Mozart himself invited Salieri and the singer Caterina Cavalieri to The Magic Flute and drove them there in his carriage. Seven weeks before his death.
The Clarinet Concerto
Written for Anton Stadler and his basset clarinet with its extended low register. Stadler gives the premiere in Prague. Mozart's last instrumental work.
November2 ·
The last entry in the catalogue
The Little Masonic Cantata, K. 623, performed at the opening of the lodge's new rooms on 18 November. Mozart conducts. It is the last work he entered in his own catalogue, and the last he heard performed.
He takes to his bed
Swollen hands and feet, fever, vomiting. Constanze and her sister Sophie nurse him. By later accounts he goes on working on the Requiem in bed.

The evening of 4 December
According to the singer Benedikt Schack, writing thirty-six years later, that evening Mozart and friends sang through the finished parts of the Requiem. The only source; it cannot be checked.
Death
Around one in the morning. He is thirty-five. The physician records the cause as 'severe miliary fever'.
The funeral
A blessing at St. Stephen's, burial at St. Marx cemetery under third-class rules: no headstone, several bodies to a grave. The site was lost.
The memorial service
At St. Michael's, arranged by Schikaneder. The finished movements of the Requiem, the Introitus and Kyrie, are performed. The first known hearing of the work.
What came after
-
Eybler starts and stops
Constanze hands the score to Joseph Eybler; he orchestrates part of the sequence and returns it. Süssmayr will finish.
-
The anniversary it was ordered for
One year since Anna von Walsegg's death. The Requiem is not ready.
-
First complete performance
Vienna, Jahn's Hall, a benefit concert for Constanze arranged by Baron van Swieten.
-
Walsegg conducts 'his' Requiem
Wiener Neustadt. The count copied the score in his own hand and put his own name on it.
Two things are missing here on purpose: the letter to Da Ponte about a 'song of death', which is considered a forgery, and the 'grey messenger', known only from Constanze's account. Both are on the Myth or fact page.
