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. [1]
In contrast to the Milanese Quartets, this quartet is in four-movement form:
Sonata form is a musical structure generally consisting of three main sections: an exposition, a development, and a recapitulation. It has been used widely since the middle of the 18th century.
The String Quartet No. 14 in G major, K. 387, nicknamed the "Spring" quartet, was composed by Wolfgang Amadeus Mozart in 1782 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 usually is played on a clarinet in A. It is 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. Sometimes the quintet is 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. Stadler was a friend to Mozart who was very talented in the instrument.
The Divertimento in E♭ major, K. 563, is a string trio, written by Wolfgang Amadeus Mozart in 1788, the year in which he completed his last three symphonies and his "Coronation" Piano Concerto. It is his last divertimento and different from his other divertimenti not only in its instrumentation but also in its compositorial ambition and scope.
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 Flute Concerto No. 1 in G major, K. 313, was written in 1778 by Wolfgang Amadeus Mozart.
The six String Quartets, Op. 76, by Joseph Haydn were composed in 1797 or 1798 and dedicated to the Hungarian count Joseph Georg von Erdődy (1754–1824). They form the last complete set of string quartets that Haydn composed. At the time of the commission, Haydn was employed at the court of Prince Nicolaus Esterházy II and was composing the oratorio The Creation as well as Princess Maria Hermenegild Esterházy's annual mass.
The String Quintet No. 5 in D major, K. 593 was written by Wolfgang Amadeus Mozart in 1790. 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. 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 Quartet No. 16 in E-flat major, K. 428/421b, was composed by Wolfgang Amadeus Mozart in 1783. This is the third of the Haydn Quartets, a set of six string quartets he wrote during his first few years in Vienna and later dedicated to Joseph Haydn.
The Op. 33 String Quartets were written by Joseph Haydn in the summer and Autumn of 1781 for the Viennese publisher Artaria. This set of string quartets has several nicknames, the most common of which is the "Russian" quartets, because Haydn dedicated the quartets to the Grand Duke Paul of Russia and many of the quartets were premiered on Christmas Day, 1781, at the Viennese apartment of the Duke's wife, the Grand Duchess Maria Feodorovna. Some scholars theorize that the "Russian" quartets were the inspiration for Mozart's six string quartets dedicated to Haydn, but no direct evidence has been found.
Wolfgang Amadeus Mozart's String Quartet No. 17 in B-flat major, K. 458, nicknamed "The Hunt", is the fourth of the Quartets dedicated to Haydn. It was completed in 1784. It is in four movements:
Wolfgang Amadeus Mozart's String Quartet No. 15 in D minor, K. 421/417b is the second of his quartets dedicated to Haydn and the only one of the set in a minor key. Though undated in the autograph, it is believed to have been completed in 1783, while his wife Constanze Mozart was in labour with her first child Raimund. Constanze stated that the rising string figures in the second movement corresponded to her cries from the other room.
The Milanese Quartets, K. 155–160, are a set of six string quartets composed by Wolfgang Amadeus Mozart in late 1772 and early 1773 when he was sixteen and seventeen years old. They are called 'Milanese' because Mozart composed them in Milan while he was working on his opera Lucio Silla. Before this set was composed, Mozart had written one earlier string quartet, so these six quartets are 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 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.
The Piano Quartets, WoO 36, by Ludwig van Beethoven are a set of three piano quartets, completed in 1785 when the composer was aged 14. They are scored for piano, violin, viola and cello. He composed a quartet in C major, another in E-flat major, and a third in D major. They were first published posthumously in 1828, however numbered in a different order: Piano Quartet No. 1 in E-flat major, Piano Quartet No. 2 in D major, and Piano Quartet No. 3 in C major.
