His most producitve place.
The period in the Domgasse is among the most productive in Mozart’s life. Deadlines and multiple obligations shaped his daily routine, the pace of work and stress level were high: discussing projects, sketching ideas, writing out parts, copying music, practicing the piano part.
During the intense half‑year in which Mozart worked “head over heels” (Leopold Mozart) on the opera Le Nozze di Figaro, countless other works were created in parallel: the musical comedy Der Schauspieldirektor, three piano concertos, the Masonic Funeral Music, a piano rondo, two Masonic songs, a sonata for piano and violin, various operatic insertions, and several smaller wind pieces. It has been calculated that Mozart’s average daily writing output at that time amounted to an incredible six pages, each with 12 lines.
How was this astonishing workload manageable? Noise and chaos do not seem to have bothered the composer much. From letters of the 1780s we know that Mozart often continued composing long past midnight even after social evenings. From 1784 onward, Mozart tried to give piano lessons only in the afternoons “to have every morning free for writing.”
Mozart’s composed works in Domgasse 5 (according to the Köchel catalogue 2024)
In 1784, Mozart began listing almost all the compositions he wrote from that point until his death in the “Catalogue of all my works.” For each work, he added an incipit. Mozart’s catalogue of works is the unique account of his creative life, written by the composer himself.
The Köchel catalogue
K. 492. K. 525. K. 550.
Anyone who studies Mozart encounters these numbers everywhere—they are the universal system for the precise identification of his works. The Köchel catalogue was compiled in 1862 by the Austrian musicologist Ludwig von Köchel and arranges Mozart’s entire output in chronological order. Every composition receives a K. number—from the earliest childhood pieces to the unfinished Requiem. To this day, it remains the worldwide standard reference for Mozart’s music.
The International Mozarteum Foundation Salzburg has fully digitized the catalogue. Scholars, music lovers, and curious explorers from around the world can now search and rediscover Mozart’s works conveniently online.

Le Nozze di Figaro – Opera buffa in four acts
Dated: 29 April 1786
In a letter to his daughter dated 3–5 November 1785, Leopold Mozart writes that he had not heard from Wolfgang for six weeks; Wolfgang had mentioned something about a new “opera,” and Leopold added that one would see. In his next letter to Maria Anna, dated 11–12 November 1785, he writes:
“At last I have received a letter from your brother dated 2 November, consisting of 12 lines. He asks for forgiveness because he must finish the opera, Le Nozze di Figaro, in great haste… that he has moved all his pupils to the afternoon so that he may have the morning free for writing, etc. I know the piece; it is a very laborious work, and the translation from the French must certainly have been altered to suit an opera if it is to have effect. God grant that it turns out well in performance; I have no doubt about the music.”
The literary source of Le Nozze di Figaro is Pierre‑Augustin Caron de Beaumarchais’ La folle journée ou Le mariage de Figaro (1776).
Mozart chose this highly successful play as the basis for his new opera. The librettist Lorenzo da Ponte adapted the plot in such a way that political connotations were avoided. Beaumarchais’ play was banned in Vienna, though the printed German translation was not.
The opera premiered on 1 May 1786 at the Burgtheater in Vienna, with a total of ten performances.
After a break of two and a half years, the work was performed again in a second version. Mozart altered the opera because the principal singers had changed, and he composed two new arias, K. 577 and K. 579. Outside Vienna, this second version is not known and plays no role in modern performance practice.
