The String Quartet No. 20 in D major, K. 499, was written in 1786 in Vienna by Wolfgang Amadeus Mozart. It was published by – if not indeed written for – his friend Franz Anton Hoffmeister. Because of this, the quartet has acquired the nickname Hoffmeister. Hoffmeister had started issuing a series of chamber-music publications in 1785, including Mozart's K. 499 as well as Joseph Haydn's String Quartet No. 35, Op. 42.
The String Quartet No. 14 in G major, K. 387, nicknamed the "Spring" quartet, was composed by Wolfgang Amadeus Mozart in 1782 while in Vienna. In the composer's inscription on the title page of the autograph score is stated: "li 31 di decembre 1782 in vienna". The work was perhaps edited in 1783. This is the first of the Haydn Quartets, a set of six string quartets he wrote during his first few years in Vienna and dedicated to Joseph Haydn.
Wolfgang Amadeus Mozart's Clarinet Quintet, K. 581, was written in 1789 for the clarinetist Anton Stadler. A clarinet quintet is a work for one clarinet and a string quartet. Although originally written for basset clarinet, in contemporary performances it is usually played on a clarinet in A. It was Mozart's only completed clarinet quintet, and is one of the earliest and best-known works written especially for the instrument. It remains to this day one of the most admired of the composer's works. The quintet is sometimes referred to as the Stadler Quintet; Mozart so described it in a letter of April 1790. Mozart also wrote a trio for clarinet, viola and piano for Stadler, the so-called Kegelstatt Trio, in 1786.
The Adagio and Fugue in C minor, K. 546, is a composition by Wolfgang Amadeus Mozart for strings. Mozart entered it into his own work catalogue on 26 June 1788 in Vienna as "A short Adagio for two violins, viola and bass, for a fugue which I wrote some time ago for two Pianos". The fugue in question was the two piano fugue in C minor, K. 426, written in December 1783.
The Piano Concerto No. 27 in B♭ major, K. 595, is Wolfgang Amadeus Mozart's last piano concerto; it was first performed early in 1791, the year of his death.
The String Quartet No. 19 in C Major, K. 465 by Wolfgang Amadeus Mozart, nicknamed "Dissonance" on account of its unusual slow introduction, is perhaps the most famous of his quartets.
The String Quintet No. 4 in G minor, K. 516, written by Wolfgang Amadeus Mozart, is like all of Mozart's string quintets a "viola quintet" in that it is scored for string quartet and an extra viola . The mood of the piece is dark and melancholic, typical of Mozart's G minor works.
The String Quintet No. 3 in C major, K. 515 was written by Wolfgang Amadeus Mozart. Like all of Mozart's string quintets, it is a "viola quintet" in that it is scored for string quartet and an extra viola.
The Quintet in E♭ major for Piano and Winds, K. 452, was composed by Wolfgang Amadeus Mozart on March 30, 1784 and premiered two days later at the Imperial and Royal National Court Theater in Vienna. Shortly after the premiere, Mozart wrote to his father that "I myself consider it to be the best thing I have written in my life." It is scored for piano, oboe, clarinet, horn and bassoon.
The String Quintet No. 6 in E-flat major, K. 614, was completed by Wolfgang Amadeus Mozart on April 12, 1791. It is Mozart's last major chamber work. Like all of Mozart's string quintets, it is a "viola quintet" in that it is scored for string quartet and an extra viola
The String Quintet No. 1 in B flat major, K. 174, was written by Wolfgang Amadeus Mozart in December 1773. Unlike Mozart's other viola quintets, which are scored for two violins, two violas and cello, this early work is scored for two violins, two violas and basso. It is inspired by Michael Haydn viola quintets in C major and G major, written earlier in the same year.
The String Quintet No. 2 in C minor, K. 406/516b, was written by Wolfgang Amadeus Mozart in 1787. Like all of Mozart's string quintets, it is a "viola quintet" in that it is scored for string quartet and an extra viola. Unlike his other string quintets, however, the work was not originally written for strings. Having completed the two string quintets K. 515 and K. 516, Mozart created a third by arranging his Serenade No. 12 for Winds in C minor K. 388/384a, written in 1782 or 1783 as a string quintet. Although by then Mozart was entering each new work into his catalogue of compositions, he did not enter this quintet, perhaps because it was an arrangement rather than a new work.
The Oboe Quartet in F major, K. 370/368b, was written by Wolfgang Amadeus Mozart in early 1781. The quartet is scored for oboe, violin, viola and violone basso or cello. In 1780, Mozart was invited to Munich to visit Elector Karl Theodor, who had commissioned the opera Idomeneo for a carnival celebration. While in Munich, Mozart renewed an acquaintance with Friedrich Ramm, a virtuoso oboist in the Munich orchestra. It was for Ramm that Mozart composed the quartet in order to show off his virtuosity and the improvements that had been made to the oboe at that time. One way that this piece showed off the instrument was the use of the "high F" above the staff, a note rarely played in any repertoire previously written for the oboe.
The six string quartets, K. 155–160, were composed by Wolfgang Amadeus Mozart in late 1772 and early 1773 when Mozart was sixteen and seventeen years of age. Because they were composed in Milan while he was working on his opera Lucio Silla, they are popularly known as the Milanese Quartets. Before this set was composed, Mozart had written one earlier string quartet, so these six quartets are ordinally numbered from No. 2 to No. 7. The quartets are written in a plan of keys of D-G-C-F-B♭-E♭ following the circle of fourths.
The six string quartets, K. 168–173, were composed by Wolfgang Amadeus Mozart in late 1773 in Vienna. These are popularly known as the Viennese Quartets. Mozart may have hoped to have them published at the time, but they were published only posthumously by Johann André in 1801 as Mozart's Op. 94.
Wolfgang Amadeus Mozart's String Quartet No. 1 in G major, K. 80/73f, was completed in its original three-movement form on 15 March 1770 while touring in Lodi, Lombardy. Mozart was 14 at the time. The fourth movement was added later, possibly in 1773, when Mozart and his father visited Vienna. There is a theory surrounding who this piece is in the style of, and many say the Italian cellist and composer Luigi Boccherini was the primary influence for this string quartet.
Wolfgang Amadeus Mozart's Flute Quartet No. 3 in C major, K. Anh. 171/285b, is the last of three quartets for the amateur flautist Ferdinand De Jean. Mozart's manuscript designates this work for flute, violin, viola and cello. Despite following directly after the first two flute quartets in the Köchel catalogue, the Quartet in C was almost certainly written a few years later, likely sometime between the years 1781 to 1782.
Wolfgang Amadeus Mozart composed his String Quartet No. 22 in B-flat major, K. 589 after a visit to the court of King Friedrich Wilhelm II, King of Prussia. Mozart traveled with his friend and piano student Prince Carl Lichnowsky, and during these travels they had the opportunity to stop in Potsdam and hold an audience for Mozart at the King's court. Mozart was under financial stress and hoped to hold a position at the court of King Wilhelm II. Wilhelm was an amateur cellist, which is why the set of Prussian Quartets, of which the String Quartet No. 22 is a part, features an unusually prominent role for the cello. Despite such compositional efforts by Mozart to gain employment from the king, these quartets were sold without any dedication and published by Artaria.
Wolfgang Amadeus Mozart's String Quartet No. 2 in D major, K. 155/134a, is thought to have been composed in the autumn of 1772 in Bolzano, while Mozart and his father were touring Italy. The opening movement is notable for its unusual key changes and its use of the interrupted Cadence.
Wolfgang Amadeus Mozart's Horn Quintet, K. 407 (386c), was written in 1782 for the soloist Joseph Leutgeb. The work calls for one French horn, one violin, two violas and one cello, differing from the usual two violins with the conventional string quartet.
