There is a long tradition in classical music of writing music in sets of pieces that cover all the major and minor keys of the chromatic scale. These sets typically consist of 24 pieces, one for each of the major and minor keys (sets that comprise all the enharmonic variants include 30 pieces). Examples include Johann Sebastian Bach's The Well-Tempered Clavier and Frédéric Chopin's 24 Preludes, Op. 28. Such sets are often organized as preludes and fugues or designated as preludes or études. Some composers have restricted their sets to cover only the 12 major keys or the 12 minor keys; or only the flat keys (Franz Liszt's Transcendental Études) or the sharp keys (Sergei Lyapunov's Op. 11 set). In yet another type, a single piece may progressively modulate through a set of tonalities, as occurs in Ludwig van Beethoven's 2 Preludes through all the Major Keys, Op. 39. The bulk of works of this type have been written for piano solo, but there also exist sets for piano 4-hands; two pianos; organ; guitar; two guitars; flute; recorder; oboe; violin solo; violin and piano; cello solo; cello and piano; voice and piano; and string quartet. There are examples of attempts to write full sets that, for one reason or another, were never completed (Josef Rheinberger's organ sonatas, Dmitri Shostakovich's string quartets, César Franck's L'Organiste).

This is a list of compositions by Johann Nepomuk Hummel.

Ludwig van Beethoven (baptised 17 December 1770 – 26 March 1827) was a German composer and pianist. He emerged in the Classical period under mentors such as Joseph Haydn and Wolfgang Amadeus Mozart, then expanded on what he was taught to incorporate more complex musical structure and emotional expression. His musical style was central to the development of Romantic music and the expansion of forms such as the symphony and string quartet. Among his most popular compositions are the Moonlight Sonata, Für Elise, Symphony No. 9, and Symphony No. 5, which continue to attract both casual and scholarly interest. Beethoven is widely regarded as one of the greatest and most influential composers in the history of music. Born in Bonn, Beethoven was a musical prodigy. He was initially taught intensively by his father, Johann van Beethoven, and later by Christian Gottlob Neefe. He found relief from a dysfunctional home life with the family of Helene von Breuning, whose children he loved, befriended, and taught piano. At age 21, he moved to Vienna, which subsequently became his base, and studied composition with Joseph Haydn. Beethoven gained a reputation as a virtuoso pianist, and was soon patronized by Karl Alois, Prince Lichnowsky for compositions, which resulted in his three Piano Trios, Op. 1, (the earliest works to which he accorded an opus number) in 1795. His Pathétique Sonata was composed in 1798. Around this time, Beethoven began experiencing symptoms of hearing loss. His career is divided into three periods. In the first, he composed in the classical style of Haydn and Wolfgang Amadeus Mozart. Beethoven's First Symphony premiered in 1800, and his first set of string quartets was published in 1801. In the middle period (1802–1812), he developed a distinctive style. His Third (Eroica) and Fifth Symphonies premiered in 1805 and 1808, respectively. The former was unprecedented in scale and scope. His opera, Fidelio, premiered in 1805, and was later revised. His Violin Concerto appeared in 1806. His Razumovsky quartets were published in 1808. Other middle works include the Waldstein and Appassionata sonatas for piano, the Kreutzer sonata for violin and his Seventh Symphony. His Emperor piano concerto premiered in 1811, without the composer as soloist. His late period (1812–1827) included some of his most innovative works. His Missa solemnis and his final symphony, the Ninth, premiered in 1824. The latter was the first major example of a choral symphony. His Diabelli Variations and late piano sonatas, particularly the Hammerklavier, are summits of the keyboard literature. His late string quartets, including the Große Fuge, of 1825–1826, are considered pinnacles of the genre. After several months of illness, which left him bedridden, Beethoven died on 26 March 1827 at the age of 56.

Wolfgang Amadeus Mozart's concertos for piano and orchestra are numbered from 1 to 27. The first four numbered concertos and three unnumbered concertos K. 107 are early works that are arrangements of keyboard sonatas by various contemporary composers. Concertos 7 and 10 are compositions for three and two pianos respectively. The remaining twenty-one are original compositions for solo piano and orchestra. Many of these concertos were composed by Mozart for himself to play in the Vienna concert series of 1784–86. For a long time relatively neglected, Mozart's piano concertos are recognised as among his greatest achievements. They were championed by Donald Tovey in his Essay on the Classical Concerto in 1903, and later by Cuthbert Girdlestone and Arthur Hutchings in 1940 (originally published in French) and 1948, respectively. Hans Tischler published a structural and thematic analysis of the concertos in 1966, followed by the works by Charles Rosen, and Daniel N. Leeson and Robert Levin. The first complete edition in print was not until that of Richault from around 1850; since then the scores and autographs have become widely available.

Johann Nepomuk Hummel completed his Concerto a Trombe Principale (Trumpet Concerto in E Major) in December 1803. It was performed on New Year's Day 1804 to mark Hummel's entrance into the court orchestra of Nikolaus II, Prince Esterházy as Haydn's successor. The work was composed for Viennese trumpet virtuoso and proponent of the keyed trumpet, Anton Weidinger. There are parts which Weidinger may have altered to make it easier to perform on the keyed trumpet. Originally this piece was written in E major, but today is often performed in E-flat major. This makes the fingering less difficult on modern valve trumpets. A typical performance lasts around 17 minutes.

There is a long tradition in classical music of writing music in sets of pieces that cover all the major and minor keys of the chromatic scale. These sets typically consist of 24 pieces, one for each of the major and minor keys (sets that comprise all the enharmonic variants include 30 pieces). Examples include Johann Sebastian Bach's The Well-Tempered Clavier and Frédéric Chopin's 24 Preludes, Op. 28. Such sets are often organized as preludes and fugues or designated as preludes or études. Some composers have restricted their sets to cover only the 12 major keys or the 12 minor keys; or only the flat keys (Franz Liszt's Transcendental Études) or the sharp keys (Sergei Lyapunov's Op. 11 set). In yet another type, a single piece may progressively modulate through a set of tonalities, as occurs in Ludwig van Beethoven's 2 Preludes through all the Major Keys, Op. 39. The bulk of works of this type have been written for piano solo, but there also exist sets for piano 4-hands; two pianos; organ; guitar; two guitars; flute; recorder; oboe; violin solo; violin and piano; cello solo; cello and piano; voice and piano; and string quartet. There are examples of attempts to write full sets that, for one reason or another, were never completed (Josef Rheinberger's organ sonatas, Dmitri Shostakovich's string quartets, César Franck's L'Organiste).

The list of compositions of Ludwig van Beethoven consists of 722 works written over forty-five years, from his earliest work in 1782 (variations for piano on a march by Ernst Christoph Dressler) when he was only eleven years old and still in Bonn, until his last work just before his death in Vienna in 1827. Beethoven composed works in all the main genres of classical music, including symphonies, concertos, string quartets, piano sonatas and opera. His compositions range from solo works to those requiring a large orchestra and chorus. Beethoven straddled both the Classical and Romantic periods, working in genres associated with Wolfgang Amadeus Mozart and his teacher Joseph Haydn, such as the piano concerto, string quartet and symphony, while on the other hand providing the groundwork for other Romantic composers, such as Hector Berlioz and Franz Liszt, with programmatic works such as his Pastoral Symphony and Piano Sonata "Les Adieux". Beethoven's work is typically divided into three periods: the "Early" period, where he composed in the "Viennese" style; the "Middle" or "Heroic" period, where his work is characterised by struggle and heroism, such as in the Eroica Symphony, the Fifth Symphony, the Appassionata Sonata and in his sole opera Fidelio; and the "Late" period, marked by intense personal expression and an emotional and intellectual profundity. Although his output greatly diminished in his later years, this period saw the composition of masterpieces such as the late string quartets, the final five piano sonatas, the Diabelli Variations, the Missa Solemnis and the Ninth Symphony. Beethoven's works are classified by both genre and various numbering systems. The best-known numbering system for Beethoven's works is that by opus number, assigned by Beethoven's publishers during his lifetime. Only 172 of Beethoven's works have opus numbers, divided among 138 opus numbers. Many works that were unpublished or published without opus numbers have been assigned one of "WoO" (Werke ohne Opuszahl—works without opus number), Hess or Biamonti numbers. For example, the short piano piece "Für Elise" is more fully known as the "Bagatelle in A minor, WoO 59 ('Für Elise')". Some works are also commonly referred to by their nicknames, such as the Kreutzer Violin Sonata, or the Archduke Piano Trio. Works are also often identified by their number within their genre. For example, the 14th string quartet, published as Opus 131, may be referenced either as "String Quartet No. 14" or "the Opus 131 String Quartet". The listings below include all of these relevant identifiers. While other catalogues of Beethoven's works exist, the numbers here represent the most commonly used.

Don Giovanni (Italian pronunciation: [ˈdɔn dʒoˈvanni]; K. 527; full title: Il dissoluto punito, ossia il Don Giovanni, literally 'The Rake Punished, or Don Giovanni') is an opera in two acts with music by Wolfgang Amadeus Mozart to an Italian libretto by Lorenzo Da Ponte. Its subject is a centuries-old Spanish legend about a libertine, Don Juan, as told by playwright Tirso de Molina in his 1630 play El burlador de Sevilla y convidado de piedra. It is a dramma giocoso blending comedy, melodrama and supernatural elements (although the composer entered it into his catalogue simply as opera buffa). It was premiered by the Prague Italian opera at the National Theatre (of Bohemia), now called the Estates Theatre, on 29 October 1787. Don Giovanni is regarded as one of the greatest operas of all time and has proved a fruitful subject for commentary in its own right; critic Fiona Maddocks has described it as one of Mozart's "trio of masterpieces with librettos by Da Ponte".

Franz Schubert's last three piano sonatas, D 958, 959 and 960, are his last major compositions for solo piano. They were written during the last months of his life, between the spring and autumn of 1828, but were not published until about ten years after his death, in 1838–39. Like the rest of Schubert's piano sonatas, they were mostly neglected in the 19th century. By the late 20th century, however, public and critical opinion had changed, and these sonatas are now considered among the most important of the composer's mature masterpieces. They are part of the core piano repertoire, appearing regularly on concert programs and recordings. One of the reasons for the long period of neglect of Schubert's piano sonatas seems to be their dismissal as structurally and dramatically inferior to the sonatas of Beethoven. In fact, the last sonatas contain distinct allusions and similarities to works by Beethoven, a composer Schubert venerated. Nevertheless, musicological analysis has shown that they maintain a mature, individual style. The last sonatas are now praised for that mature style, manifested in unique features such as a cyclical formal and tonal design, chamber music textures, and a rare depth of emotional expression. Each one of the three sonatas is cyclically intraconnected by diverse structural, harmonic and melodic elements tying together all movements, as well as interconnecting all three sonatas together. Consequently, they are often regarded as a trilogy. They also contain specific allusions and similarities to other Schubert compositions, such as his Winterreise song cycle; these connections point to turbulent emotions expressed in the sonatas, often understood as highly personal and autobiographical. Indeed, some researchers have suggested specific psychological narratives for the sonatas, based on historical evidence concerning the composer's life.

E major is a major scale based on E, consisting of the pitches E, F♯, G♯, A, B, C♯, and D♯. Its key signature has four sharps. Its relative minor is C-sharp minor and its parallel minor is E minor. Its enharmonic equivalent, F-flat major, has six flats and the double-flat B, which makes that key less convenient to use. The E major scale is: Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The E harmonic major and melodic major scales are:

F-sharp minor is a minor scale based on F♯, consisting of the pitches F♯, G♯, A, B, C♯, D, and E. Its key signature has three sharps. Its relative major is A major and its parallel major is F-sharp major (or enharmonically G-flat major). The F-sharp natural minor scale is: Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The F-sharp harmonic minor and melodic minor scales are:

The Piano Sonata No. 3 in B minor, Op. 58, is a piano sonata in four movements composed by Polish composer Frédéric Chopin; it is the second of the composer's three mature sonatas (the others being the Piano Sonata No. 2, Op. 35, and the Sonata for Piano and Cello in G minor, Op. 65). Completed in 1844 and published in 1845, the work is considered to be one of Chopin's most difficult compositions, both technically and musically. The work has a structure similar to Piano Sonata No. 5, Op. 81 by Johann Nepomuk Hummel. A performance of the sonata lasts around 23 to 30 minutes, depending on whether the repetition of the exposition in the first movement is observed. The work is dedicated to Countess Élise de Perthuis.

Frédéric Chopin wrote a number of preludes for piano solo. His collection of 24 Preludes, Op. 28, covers all major and minor keys. In addition, Chopin wrote three other preludes: a prelude in C♯ minor, Op. 45; a piece in A♭ major from 1834; and an unfinished piece in E♭ minor. These are sometimes referred to as Nos. 25, 26, and 27, respectively.

A piano sonata is a sonata written for a solo piano. Piano sonatas are usually written in three or four movements, although some piano sonatas have been written with a single movement (Liszt, Scriabin, Prokofiev, Berg), others with two movements (Haydn, Beethoven), some contain five (Brahms' Third Piano Sonata, Czerny's Piano Sonata No. 1, Godowsky's Piano Sonata) or even more movements. The first movement is generally composed in sonata form.

A-flat major is a major scale based on A♭, with the pitches A♭, B♭, C, D♭, E♭, F, and G. Its key signature has four flats. The A-flat major scale is: The A-flat harmonic major and melodic major scales are Its relative minor is F minor. Its parallel minor, A-flat minor, would require seven flats and is usually written as the enharmonic key of G-sharp minor instead, with five sharps. In tuning systems where the number of notes per octave is not a multiple of 12, notes such as G♯ and A♭ are not enharmonically equivalent, nor are the corresponding key signatures. These tunings can produce keys with no analogue in 12-tone equal temperament, possibly requiring double sharps, double flats, or microtonal alterations in key signatures.

Johannes Brahms (; German: [joˈhanəs ˈbʁaːms] ; 7 May 1833 – 3 April 1897) was a German composer, virtuoso pianist, and conductor of the mid-Romantic period. His music is noted for its rhythmic vitality and freer treatment of dissonance, often set within studied yet expressive contrapuntal textures. He adapted the traditional structures and techniques of a wide historical range of earlier composers. His œuvre includes four symphonies, four concertos, a Requiem, much chamber music, and hundreds of folk-song arrangements and Lieder, among other works for symphony orchestra, piano, organ, and choir. Born to a musical family in Hamburg, Brahms began composing and concertizing locally in his youth. He toured Central Europe as a pianist in his adulthood, premiering many of his own works and meeting Franz Liszt in Weimar. Brahms worked with Ede Reményi and Joseph Joachim, seeking Robert Schumann's approval through Joachim. He gained both Robert and Clara Schumann's support and guidance. Brahms stayed with Clara in Düsseldorf, becoming devoted to her amid Robert's insanity and institutionalization. The two remained close, lifelong friends after Robert's death. Brahms never married, perhaps in an effort to focus on his work as a musician and scholar. He was a self-conscious, sometimes severely self-critical composer. Though innovative, his music was considered relatively conservative within the polarized context of the War of the Romantics, an affair in which Brahms regretted his public involvement. His compositions were largely successful, attracting a growing circle of supporters, friends, and musicians. Eduard Hanslick celebrated them polemically as absolute music, and Hans von Bülow even cast Brahms as the successor of Johann Sebastian Bach and Ludwig van Beethoven, an idea Richard Wagner mocked. Settling in Vienna, Brahms conducted the Singakademie and Gesellschaft der Musikfreunde, programming the early and often "serious" music of his personal studies. He considered retiring from composition late in life but continued to write chamber music, especially for Richard Mühlfeld. Brahms's contributions and craftsmanship were admired by his contemporaries like Antonín Dvořák, whose music he enthusiastically supported, and a variety of later composers. Max Reger and Alexander Zemlinsky reconciled Brahms's and Wagner's often contrasted styles. So did Arnold Schoenberg, who emphasized Brahms's "progressive" side. He and Anton Webern were inspired by the intricate structural coherence of Brahms's music, including what Schoenberg termed its developing variation. It remains a staple of the concert repertoire, continuing to influence composers into the 21st century.

This is a list of compositions by Carl Czerny. Czerny composed a large number of pieces (up to Op. 861), including piano music (études, nocturnes, 11 sonatas, opera theme arrangements and variations) and also masses and choral music, 6 symphonies, concertos, songs, string quartets and other chamber music. Czerny himself divided his music into four categories: studies and exercises easy pieces for students brilliant pieces for concerts serious music.

The list of compositions of Ludwig van Beethoven consists of 722 works written over forty-five years, from his earliest work in 1782 (variations for piano on a march by Ernst Christoph Dressler) when he was only eleven years old and still in Bonn, until his last work just before his death in Vienna in 1827. Beethoven composed works in all the main genres of classical music, including symphonies, concertos, string quartets, piano sonatas and opera. His compositions range from solo works to those requiring a large orchestra and chorus. Beethoven straddled both the Classical and Romantic periods, working in genres associated with Wolfgang Amadeus Mozart and his teacher Joseph Haydn, such as the piano concerto, string quartet and symphony, while on the other hand providing the groundwork for other Romantic composers, such as Hector Berlioz and Franz Liszt, with programmatic works such as his Pastoral Symphony and Piano Sonata "Les Adieux". Beethoven's work is typically divided into three periods: the "Early" period, where he composed in the "Viennese" style; the "Middle" or "Heroic" period, where his work is characterised by struggle and heroism, such as in the Eroica Symphony, the Fifth Symphony, the Appassionata Sonata and in his sole opera Fidelio; and the "Late" period, marked by intense personal expression and an emotional and intellectual profundity. Although his output greatly diminished in his later years, this period saw the composition of masterpieces such as the late string quartets, the final five piano sonatas, the Diabelli Variations, the Missa Solemnis and the Ninth Symphony. Beethoven's works are classified by both genre and various numbering systems. The best-known numbering system for Beethoven's works is that by opus number, assigned by Beethoven's publishers during his lifetime. Only 172 of Beethoven's works have opus numbers, divided among 138 opus numbers. Many works that were unpublished or published without opus numbers have been assigned one of "WoO" (Werke ohne Opuszahl—works without opus number), Hess or Biamonti numbers. For example, the short piano piece "Für Elise" is more fully known as the "Bagatelle in A minor, WoO 59 ('Für Elise')". Some works are also commonly referred to by their nicknames, such as the Kreutzer Violin Sonata, or the Archduke Piano Trio. Works are also often identified by their number within their genre. For example, the 14th string quartet, published as Opus 131, may be referenced either as "String Quartet No. 14" or "the Opus 131 String Quartet". The listings below include all of these relevant identifiers. While other catalogues of Beethoven's works exist, the numbers here represent the most commonly used.
