Symphony No. 40 in G minor, K. 550 was written by Wolfgang Amadeus Mozart in 1788. It is sometimes referred to as the "Great G minor symphony", to distinguish it from the "Little G minor symphony", No. 25. The two are the only extant minor key symphonies Mozart wrote.
Lo sposo deluso, ossia La rivalità di tre donne per un solo amante is a two-act opera buffa, K. 430, composed by Wolfgang Amadeus Mozart between 1783 and 1784. However, the opera was never completed and only a 20-minute fragment from act 1 exists.
Symphony No. 35 in D major, K. 385, also known as the Haffner Symphony, was composed by Wolfgang Amadeus Mozart in 1782. It was commissioned by the Haffners, a prominent Salzburg family, for the occasion of the ennoblement of Sigmund Haffner the Younger. The Haffner Symphony should not be confused with the eight-movement Haffner Serenade, another piece Mozart wrote on commission from the same family in 1776.
The Symphony No. 31 in D major, K. 297/300a, better known as the Paris Symphony, is one of the most famous symphonies by Wolfgang Amadeus Mozart. It may have been first of his symphonies to be published when Seiber released their edition in 1779.
The Symphony No. 32 in G major, K. 318, was written by Wolfgang Amadeus Mozart in 1779, after his return from Paris.
The Symphony No. 75 in D major is a symphony composed by Joseph Haydn between 1779 and 1781.
The Symphony No. 8 in D major,, by Wolfgang Amadeus Mozart is dated December 13, 1768. Mozart wrote the symphony in Vienna, when he was twelve years old, at a time when he and his family were already due to have returned home to Salzburg. In a letter to his friend in Salzburg, Lorenz Hagenauer, Leopold Mozart says of the delay that "we could not bring our affairs to a conclusion earlier, even though I endeavored strenuously to do so." The autograph of the Symphony No. 8 is today preserved in the Staatsbibliothek Preusischer Kulturbesitz in Berlin.
The Symphony No. 26 in E♭ major, K. 184/161a, was written by Wolfgang Amadeus Mozart and completed on March 30, 1773, one month after he returned from his third Italian tour.
Symphony No. 6 in F major, K. 43, was composed by Wolfgang Amadeus Mozart in 1767. According to Alfred Einstein in his 1937 revision of the Köchel catalogue, the symphony was probably begun in Vienna and completed in Olomouc, a Moravian city to which the Mozart family fled to escape a Viennese smallpox epidemic; see Mozart and smallpox.
Symphony No. 9 in C major, K. 73/75a, by Wolfgang Amadeus Mozart, has an uncertain provenance. The most likely date of its composition appears to be late 1769 or early 1770 during Mozart's first Italian journey, although some authorities have dated it "probably not before early summer 1772". It may have been started in Salzburg, before the first Italian journey began, and completed during the trip.
Symphony No. 13 in F major, K. 112, by Wolfgang Amadeus Mozart, was written in Milan during his second journey to Italy in the autumn of 1771. The symphony is in four movements, the second of which is scored for strings alone. The third movement minuet may have been written earlier, and then incorporated into the symphony—the autograph manuscript shows the minuet copied in Leopold's hand. Nicholas Kenyon describes Symphony No. 13 as the last in "conventional mode"—thereafter "we are in the beginnings of a different world."
Symphony No. 11 in D major, K. 84/73q, was at one time considered unquestionably to be the work of Wolfgang Amadeus Mozart. Its status has, however, been challenged, and remains uncertain. It is believed to date from 1770, and may have been written in Milan or Bologna, if it is a genuine Mozart work. An early manuscript from Vienna attributes the work to Wolfgang, but nineteenth-century copies of the score attribute it respectively to Leopold Mozart and to Carl Dittersdorf. Neal Zaslaw writes: "A comparison of the results of two stylistic analyses of the work's first movement with analyses of unquestionably genuine first movements of the period by the three composers suggests that Wolfgang is the most likely of the three to have been the composer of K73q".
This list of Mozart symphonies of spurious or doubtful authenticity contains 39 symphonic works whose initial attribution to Wolfgang Amadeus Mozart has subsequently been proved spurious, or is the subject of continuing doubt. The number of symphonies actually written by Mozart is imprecisely known; of the 41 formally numbered, three are established as by other composers and another, No. 11, is considered by scholars to be of uncertain authenticity. Outside the accepted sequence 1–41, however, there are around twenty other genuine Mozart symphonies, and beyond these, a larger number of problematic works which have not been authenticated as Mozart's. Some of these may be genuine; dubious works are often treated as authentic by the compilers of collected editions—eight are in the main body of the 1991 Neue Mozart-Ausgabe, and another two are included in the supplementary 2000 volume of works of doubtful authenticity. Some, however, have long been accepted as the works of other composers, who in many instances have been positively identified.
Between 1769 and 1773, the young Wolfgang Amadeus Mozart and his father Leopold Mozart made three Italian journeys. The first, an extended tour of 15 months, was financed by performances for the nobility and by public concerts, and took in the most important Italian cities. The second and third journeys were to Milan, for Wolfgang to complete operas that had been commissioned there on the first visit. From the perspective of Wolfgang's musical development the journeys were a considerable success, and his talents were recognised by honours which included a papal knighthood and memberships in leading philharmonic societies.
The Symphony in F major "No. 43", K. 76/42a, was probably written by Wolfgang Amadeus Mozart.
The Symphony in D major "No. 45", K. 95/73n, was probably written by Wolfgang Amadeus Mozart in 1770 in Rome.
The Symphony in D major "No. 47", K. 97/73m, was probably written by Wolfgang Amadeus Mozart in 1770 in Rome.
The Symphony in D major "No. 44", K. 81/73l, may have been written by Wolfgang Amadeus Mozart in 1770 in Rome, although it has sometimes also been attributed to his father Leopold Mozart. It is now also catalogued as Eisen D 14 in Cliff Eisen's catalogue of Leopold Mozart's symphonies.
The Kyrie in D minor, K. 341/368a, is a sacred composition for choir and large classical orchestra by Wolfgang Amadeus Mozart. It is a setting of the Kyrie, the first section of the Mass, using an orchestra of two flutes, two oboes, two clarinets in A, two bassoons, two trumpets in D, four horns, two timpani in D and A, organ, and strings, as well as the chorus. It lasts approximately seven minutes in performance.
