In music, the three-key exposition is a particular kind of exposition used in sonata form.
Normally, a sonata form exposition has two main key areas. The first asserts the primary key of the piece, that is, the tonic. The second section moves to a different key, establishes that key firmly, arriving ultimately at a cadence in that key. For the second key, composers normally chose the dominant for major-key sonatas, and the relative major (or less commonly, the minor-mode dominant) for minor-key sonatas. The three-key exposition moves not directly to the dominant or relative major, but indirectly via a third key; hence the name.
Sonata form is a musical structure 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 Piano Sonata No. 12 in F major, K. 332 (300k) by Wolfgang Amadeus Mozart was published in 1784 along with the Piano Sonata No. 10 in C major, K. 330, and Piano Sonata No. 11, K. 331. Mozart wrote these sonatas either while visiting Munich in 1781, or during his first two years in Vienna. Some believe, however that Mozart wrote this and the other sonatas during a summer 1783 visit to Salzburg made for the purpose of introducing his wife, Constanze to his father, Leopold. All three sonatas were published in Vienna in 1784 as Mozart's Op. 6.
The Trout Quintet (Forellenquintett) is the popular name for the Piano Quintet in A major, D. 667, by Franz Schubert. The piano quintet was composed in 1819, when he was 22 years old; it was not published, however, until 1829, a year after his death.
The Piano Quintet in E-flat major, Op. 44, by Robert Schumann was composed in 1842 and received its first public performance the following year. Noted for its "extroverted, exuberant" character, Schumann's piano quintet is considered one of his finest compositions and a major work of nineteenth-century chamber music. Composed for piano and string quartet, the work revolutionized the instrumentation and musical character of the piano quintet and established it as a quintessentially Romantic genre.
The Piano Quintet in F minor, Op. 34, by Johannes Brahms was completed during the summer of 1864 and published in 1865. It was dedicated to Her Royal Highness Princess Anna of Hesse. Like most piano quintets composed after Robert Schumann's Piano Quintet (1842), it is written for piano and string quartet.
Sonata rondo form is a musical form often used during the Classical music era. As the name implies, it is a blend of sonata form and rondo form.
Beethoven's Piano Sonata No. 21 in C major, Op. 53, known as the Waldstein, is one of the three most notable sonatas of his middle period. Completed in summer 1804 and surpassing Beethoven's previous piano sonatas in its scope, the Waldstein is a key early work of Beethoven's "Heroic" decade (1803–1812) and set a standard for piano composition in the grand manner.
The Piano Sonata No. 32 in C minor, Op. 111, is the last of Ludwig van Beethoven's piano sonatas. Along with Beethoven's 33 Variations on a waltz by Anton Diabelli, Op. 120 (1823) and his two collections of bagatelles—Op. 119 (1822) and Op. 126 (1823)—this was one of Beethoven's last compositions for piano. The work was written between 1821 and 1822. Like other "late period" sonatas, it contains fugal elements. It was dedicated to his friend, pupil, and patron, Archduke Rudolf.
Ludwig van Beethoven's Piano Sonata No. 3 in C major, Op. 2, No. 3, is a sonata written for solo piano, composed in 1795. It is dedicated to Joseph Haydn and is often referred to as Beethoven's first virtuosic piano sonata. The three Op. 2 sonatas all contain four movements each, an unusual length which seems to show that Beethoven was aspiring towards composing a symphony. It is both the weightiest and longest of the three Op. 2 sonatas, lasting over 25 minutes, presenting many difficulties, including difficult trills, awkward hand movements, and forearm rotation. It is Beethoven's second longest piano sonata in his early period, only to Beethoven's Grand Sonata in E♭ Major, Op. 7, published a year later.
The String Quartet No. 15 in A minor, Op. 132, by Ludwig van Beethoven, was written in 1825, given its public premiere on November 6 of that year by the Schuppanzigh Quartet and was dedicated to Count Nikolai Galitzin, as were Opp. 127 and 130. The number traditionally assigned to it is based on the order of its publication; it is actually the thirteenth quartet in order of composition.
E-flat major is a major scale based on E♭, with the pitches E♭, F, G, A♭, B♭, C, and D. Its key signature has three flats: B, E, and A. Its relative minor is C minor, while its parallel minor is E♭ minor.
Franz Schubert's final chamber work, the String Quintet in C major is sometimes called the "Cello Quintet" because it is scored for a standard string quartet plus an extra cello instead of the extra viola which is more usual in conventional string quintets. It was composed in 1828 and completed just two months before the composer's death. The first public performance of the piece did not occur until 1850, and publication occurred three years later in 1853. Schubert's only full-fledged string quintet, it has been praised as "sublime" or "extraordinary" and as possessing "bottomless pathos," and is generally regarded as Schubert's finest chamber work as well as one of the greatest compositions in all chamber music.
The Piano Sonata No. 31 in A♭ major, Op. 110, by Ludwig van Beethoven was composed in 1821. It is the central piano sonata in the group of three, Opp. 109–111, which he wrote between 1820 and 1822, and the thirty-first of his published piano sonatas.
Ludwig van Beethoven's Piano Sonata No. 6 in F major, Op. 10, No. 2, was dedicated to the Countess Anne Margarete von Browne, and written from 1796 to 1798.
The Piano Sonata No. 25 in G major, Op. 79, a work in three movements, was written by Ludwig van Beethoven in 1809. It is alternatively titled "Cuckoo" or "Sonatina," and it is notable for its shortness.
Beethoven's Piano Sonata No. 1 in F minor, Op. 2, No. 1, was written in 1795 and dedicated to Joseph Haydn.
Beethoven's Piano Sonata No. 11 in B♭ major, Op. 22, was composed in 1800, and published two years later. Beethoven regarded it as the best of his early sonatas, though some of its companions in the cycle have been at least as popular with the public.
In the compositions of Ludwig van Beethoven, the key of C minor is commonly regarded as significant: works for which he chose this key are felt to be powerful and emotionally stormy.
The Piano Quartet No. 3 in C minor, Op. 60, completed by Johannes Brahms in 1875, is scored for piano, violin, viola and cello. It is sometimes called the Werther Quartet after Goethe's The Sorrows of Young Werther.
The Piano Quartets, WoO 36, by Ludwig van Beethoven are a set of three piano quartets, completed in 1785 when the composer was aged 15. 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.
