Adagio and Allegro in F minor for a mechanical organ, K. 594, is a composition by Wolfgang Amadeus Mozart, completed in late 1790.

The Adagio in B minor, K. 540, is a composition for piano solo by Wolfgang Amadeus Mozart. He entered it into his Verzeichnis aller meiner Werke (Catalogue of all my Works) on 19 March 1788. At 57 measures, the duration of the piece is largely based on the performer's interpretation, including the decision of whether to do both repeats; it may last between 5+1⁄2 and 16 minutes. The key of B minor is very rare in Mozart's compositions; it is used in only one other instrumental work, the slow movement from the Flute Quartet No. 1 in D major, K. 285. Mozart specifically noted the key of B minor in his catalogue, which he did for no other piece. In 1841 Franz Xaver Wolfgang Mozart used themes from this composition in his own Fest-Chor. The Austrian composer and academic Gerhard Präsent has made an arrangement for string quartet in four movements Fantasy Quartet in D in which this piece acts as the third one. The autograph is at the Stiftelsen Musikkulturens Främjande Library, Stockholm.

Wolfgang Amadeus Mozart (1756–1791) was a prolific and influential composer of the Classical period who wrote in many genres. Perhaps his best-admired works can be found within the categories of operas, piano concertos, piano sonatas, symphonies, string quartets, and string quintets. Mozart also wrote many violin sonatas; other forms of chamber music; violin concertos, and other concertos for one or more solo instruments; masses, and other religious music; organ music; masonic music; and numerous dances, marches, divertimenti, serenades, and other forms of light entertainment.

The Nannerl Notenbuch, or Notenbuch für Nannerl (English: Nannerl's Music Book) is a book in which Leopold Mozart, from 1759 to about 1764, wrote pieces for his daughter, Maria Anna Mozart (known as "Nannerl"), to learn and play. His son Wolfgang also used the book, in which his earliest compositions were recorded (some penned by his father). The book contains simple short keyboard (typically harpsichord) pieces, suitable for beginners; there are many anonymous minuets, some works by Leopold, and a few works by other composers including Carl Philipp Emanuel Bach and the Austrian composer Georg Christoph Wagenseil. There are also some technical exercises, a table of intervals, and some modulating figured basses. The notebook originally contained 48 bound pages of music paper, but only 36 pages remain, with some of the missing 12 pages identified in other collections. Because of the simplicity of the pieces it contains, the book is often used to provide instruction to beginning piano players.

The Piano Concerto No. 24 in C minor, K. 491, is a concerto composed by Wolfgang Amadeus Mozart for keyboard (usually a piano or fortepiano) and orchestra. Mozart composed the concerto in the winter of 1785–1786, finishing it on 24 March 1786, three weeks after completing his Piano Concerto No. 23 in A major. As he intended to perform the work himself, Mozart did not write out the soloist's part in full. The premiere was in early April 1786 at the Burgtheater in Vienna. Chronologically, the work is the twentieth of Mozart's 23 original piano concertos. The work is one of only two minor-key piano concertos that Mozart composed, the other being the No. 20 in D minor. None of Mozart's other piano concertos features a larger array of instruments: the work is scored for strings, woodwinds, horns, trumpets and timpani. The first of its three movements, Allegro, is in sonata form and is longer than any opening movement of Mozart's earlier concertos. The second movement, Larghetto, in E♭ major—the relative major of C minor—features a strikingly simple principal theme. The final movement, Allegretto, is a theme and eight variations in C minor. The work is one of Mozart's most advanced compositions in the concerto genre. Its early admirers included Ludwig van Beethoven and Johannes Brahms. Musicologist Arthur Hutchings declared it to be, taken as a whole, Mozart's greatest piano concerto.

The Köchel catalogue (German: Köchel-Verzeichnis) is a catalogue of compositions by Wolfgang Amadeus Mozart, originally created by Ludwig Ritter von Köchel, in which the entries are abbreviated K. or KV. Its numbers reflect the ongoing task of compiling the chronology of Mozart's works, and provide a shorthand reference to the compositions. For example, according to Köchel's counting, Requiem in D minor is the 626th piece Mozart composed, thus is designated K. 626. Köchel's original catalogue (1862) has been revised several times. Catalogue numbers from these revised editions are indicated either by parentheses or by superscript: K. 49 (47d) or K.6 47d refers to the work numbered 47d in the sixth edition. The catalog was originally chronological, though revisions made chronological ordering of Mozart's works difficult and as of 2024 a new organizational system is used for the ninth version.

Fantasia No. 4 in C minor, K. 475 is a composition for solo piano composed by Wolfgang Amadeus Mozart in Vienna on 20 May 1785. It was published as Opus 11 in December 1785, together with the Sonata in C minor, K. 457, the only one of Mozart's piano sonatas to be published together with a work of a different genre. Starting in the key of C minor, the piece is marked Adagio but then, after a section in D major, moves into an allegro section which goes from A minor to G minor, F major, and then F minor. It then moves into a fourth section in B♭ major marked Andantino and then moves to a più allegro section starting in G minor and modulating through many keys before the opening theme returns in the original key of C minor. Most of the music is written with no sharps or flats in the key signature and uses accidentals—only the fourth section, in B♭ major, is given a key signature. The autograph manuscript of this composition was auctioned by Sotheby's on 21 November 1990, and is now preserved in the International Mozarteum Foundation. The Austrian composer Ignaz von Seyfried combined this work with the Sonata in C minor, K. 457, and produced a four-movement arrangement for orchestra, the "Grande Fantaisie" in C minor. Tchaikovsky arranged the Andantino section to a vocal quartet with piano by the name "Night" ("Ночь").

In Western musical theory, a cadence (from Latin cadentia 'a falling') is the end of a phrase in which the melody or harmony creates a sense of full or partial resolution, especially in music of the 16th century onwards. A harmonic cadence is a progression of two or more chords that concludes a phrase, section, or piece of music. A rhythmic cadence is a characteristic rhythmic pattern that indicates the end of a phrase. A cadence can be labeled "weak" or "strong" depending on the impression of finality it gives. While cadences are usually classified by specific chord or melodic progressions, the use of such progressions does not necessarily constitute a cadence—there must be a sense of closure, as at the end of a phrase. Harmonic rhythm plays an important part in determining where a cadence occurs. The word "cadence" sometimes slightly shifts its meaning depending on the context; for example, it can be used to refer to the last few notes of a particular phrase, or to just the final chord of that phrase, or to types of chord progressions that are suitable for phrase endings in general. Cadences are strong indicators of the tonic or central pitch of a passage or piece. The musicologist Edward Lowinsky proposed that the cadence was the "cradle of tonality".

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.

C minor is a minor scale based on C, consisting of the pitches C, D, E♭, F, G, A♭, and B♭. Its key signature consists of three flats. Its relative major is E♭ major and its parallel major is C major. The C natural minor scale is: Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The C harmonic minor and melodic minor scales are:

Franz Schubert (31 January 1797 – 19 November 1828) was an extremely prolific Austrian composer. He composed some 1500 works (or, when collections, cycles and variants are grouped, some thousand compositions). The largest group are the lieder for piano and solo voice (over six hundred), and nearly as many piano pieces. Schubert also composed some 150 part songs, some 40 liturgical compositions (including several masses) and around 20 stage works like operas and incidental music. His orchestral output includes thirteen symphonies (seven completed) and several overtures. Schubert's chamber music includes over 20 string quartets, and several quintets, trios and duos. This article constitutes a complete list of Schubert's known works organized by their genre. The complete output is divided in eight series, and in principle follows the order established by the Neue Schubert-Ausgabe printed edition. The works found in each series are ordered ascendingly according to Deutsch numbers, the information of which attempts to reflect the most current information regarding Schubert's catalogue. The list below includes the following information: D – the catalogue number assigned by Otto Erich Deutsch or NSA authorities Genre – the musical genre to which the piece belongs. This has been omitted when the genre is self-explanatory or unnecessary, i.e. piano dances Title – the title of the work Incipit – the first line(s) of text, as pertaining to vocal works Scoring – the instrumentation and/or vocal forces required for the work Informal Title – any additional names by which the work is known, when applicable Former Deutsch Number – information on Deutsch numbers that have been reassigned, when applicable Date – the known or assumed date of composition, when available; or date of publication Opus Number – the opus number of the original publication of the work, when applicable Setting – the order of setting as it pertains to vocal works that have numerous settings of the same text Version – the number of version as it pertains to works or vocal settings that have more than one existing version Notes – any additional information concerning the work: alternate titles, completeness, relation to other works, authorship, etc.

The Klavierstück in F (Piece in F for keyboard), K. 33B/Anh.A 6, is a keyboard work written by Wolfgang Amadeus Mozart sometime during early October 1766; its tempo marking is Allegro. It is 26 bars long, divided into two sections of 12 and 14 bars, each repeated. It is suspected to be an arrangement of work by another composer. Mozart wrote this piece in pencil on the back of a circular by the Zürcher Musikkollegium (Zurich Music College) dated 30 September 1766, when the Mozart family came to the end of their Grand Tour. The circular invited sponsors, music lovers and other people who might be interested to concerts by "the young (9 years old) Master Mozart as well as his maiden sister" (Maria Anna – Nannerl) on October 7 and 9. It can be assumed that Mozart played or improvised this lively piece in one of those concerts, the programs to which are lost. Mozart wrote it on the back of the circular probably as a souvenir for the college's board; otherwise he would have used his sister's notebook or his third book of sketches (Skizzenbuch), which is also lost. The autograph became known very late (in 1942), and so is missing from Alfred Einstein's 3rd edition of the Köchel catalogue. This piece appeared shortened in the 1984 film Amadeus, when the child Mozart played it blindfolded on the harpsichord.

Wolfgang Amadeus Mozart's Piano Sonata in F major, K. 547a (Anh. 135) is a sonata in two movements. It was originally published as an original sonata by Breitkopf and Härtel in 1799 but was soon found to be an amalgam of movements culled from other compositions. It is sometimes called Mozart's Piano Sonata No. 19.

Wolfgang Amadeus Mozart's Piano Sonata No. 1 in C major, K. 279 / 189d (1774), is a piano sonata in three movements. Except for the first part of the opening movement, it was written during the visit Mozart paid to Munich for the production of La finta giardiniera from December 1774 to March 1775. Although Mozart is known to have written at least five other solo piano sonatas in his youth, K. 279 is the first of his 18 extant solo piano sonatas. A typical performance of the sonata takes about 14 minutes.

The Piano Sonata No. 11 in A major, K. 331 / 300i, by Wolfgang Amadeus Mozart is a piano sonata in three movements. The sonata was published by Artaria in 1784, alongside Nos. 10 and 12 (K. 330 and K. 332). The third movement of this sonata, the "Rondo alla Turca", or "Turkish March", is often heard on its own and regarded as one of Mozart's best-known piano pieces.

The Piano Sonata No. 11 in A major, K. 331 / 300i, by Wolfgang Amadeus Mozart is a piano sonata in three movements. The sonata was published by Artaria in 1784, alongside Nos. 10 and 12 (K. 330 and K. 332). The third movement of this sonata, the "Rondo alla Turca", or "Turkish March", is often heard on its own and regarded as one of Mozart's best-known piano pieces.

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 Piano Sonata No. 13 in B-flat major, K. 333 (315c), also known as the "Linz Sonata", was composed by Wolfgang Amadeus Mozart in Linz at the end of 1783. The autograph manuscript of the sonata is preserved in the Berlin State Library.

The Piano Sonata No. 14 in C minor, K. 457, by Wolfgang Amadeus Mozart was composed and completed in 1784, with the official date of completion recorded as 14 October 1784 in Mozart's own catalogue of works. It was published in December 1785 together with the Fantasy in C minor, K. 475, as Opus 11 by the publishing firm Artaria, Mozart's main Viennese publisher. The title page bore a dedication to Theresia von Trattner (1758–1793), who was one of Mozart's pupils in Vienna. Her husband, Thomas von Trattner (1717–1798), was an important publisher as well as Mozart's landlord in 1784. Eventually, the Trattners would become godparents to four of Mozart's children. The piano sonata was composed during the approximately 10-year period of Mozart's life as a freelance artist in Vienna after he removed himself from the patronage of the Archbishop of Salzburg in 1781. It is one of the earliest of only six sonatas composed during the Vienna years, and was probably written either as a teaching tool or for personal use. Sonatas during this time were generally written for the domestic sphere – as opposed to a symphony or concerto, they were designed to convey ideas in a small, intimate setting. A typical performance takes about 18 minutes.

Wolfgang Amadeus Mozart's Piano Sonata No. 15 in F major, KV 533/494 (finished 3 January 1788) is a sonata in three movements: A typical performance takes about 23 minutes. The Rondo was originally a stand-alone piece composed by Mozart in 1786 (Rondo No. 2, K. 494 in the Köchel catalogue). In 1788, Mozart wrote the first two movements of K. 533 and incorporated a revised version of K. 494 as the finale, having lengthened it in order to provide a more substantial counterpart to the other two movements.

The Piano Sonata No. 16 in C major, K. 545, by Wolfgang Amadeus Mozart was described by Mozart in his own thematic catalogue as "for beginners", and it is very commonly known by the nickname Sonata facile or Sonata semplice. Mozart added the work to his catalogue on June 26, 1788, the same date as his Symphony No. 39. The exact circumstances of the work's composition are not known. Although the piece is well known today, it was not published in Mozart's lifetime and first appeared in print in 1805. A typical performance takes about 11 minutes.

The Piano Sonata No. 2 in B♭ minor, Op. 35, is a piano sonata in four movements by Polish composer Frédéric Chopin. Chopin completed the work while living in George Sand's manor in Nohant, some 250 km (160 mi) south of Paris, a year before it was published in 1840. The first of the composer's three mature sonatas (the others being the Piano Sonata No. 3 in B minor, Op. 58 and the Sonata for Piano and Cello in G minor, Op. 65), the work is considered to be one of the greatest piano sonatas of the literature. The third movement of the Piano Sonata No. 2 is Chopin's famous funeral march (French: Marche funèbre; Polish: Marsz żałobny) which was composed at least two years before the remainder of the work and has remained, by itself, one of Chopin's most popular compositions. The Piano Sonata No. 2 carries allusions and reminiscences of music by J. S. Bach and by Ludwig van Beethoven; Beethoven's Piano Sonata No. 12 also has a funeral march as its third movement. A typical performance of Chopin's second sonata lasts between 21 and 25 minutes, depending on whether the repetition of the first movement's exposition is observed. While the Piano Sonata No. 2 gained instant popularity with the public, critical reception was initially more doubtful. Robert Schumann, among other critics, argued that the work was structurally inferior and that Chopin "could not quite handle sonata form", a criticism that did not withstand time. The work has been recorded by numerous pianists and is regularly programmed in concerts and piano competitions. The Marche funèbre exists in countless arrangements and has been performed at funerals all over the world (including Chopin's own), having become an archetypal evocation of death.

The Piano Sonata No. 18 in D major, K. 576, was composed by Wolfgang Amadeus Mozart as part of a set of six for Princess Frederica Charlotte of Prussia in 1789. It is often nicknamed "The Hunt" or "The Trumpet Sonata", for the hornlike opening. The sonata, having a typical performance duration of about 15 minutes, is Mozart's last. It was the only one of the intended set of six.

Wolfgang Amadeus Mozart's Piano Sonata No. 2 in F major, K. 280/189e, (1774) is a piano sonata in three movements. The work was written down along with other piano sonatas during the visit Mozart paid to Munich for the production of La finta giardiniera from late 1774 to the beginning of the following March. A typical performance of the sonata takes about 14 minutes.

Wolfgang Amadeus Mozart's Piano Sonata No. 3 in B♭ major, K. 281/189f, (1775) is a piano sonata in three movements: A performance takes approximately between 11½ and 15 minutes. This piano sonata is one of the most virtuosic pieces Mozart ever composed, written during the visit Mozart paid to Munich for the production of La finta giardiniera from late 1774 to the beginning of the following March.

Wolfgang Amadeus Mozart's Piano Sonata No. 4 in E♭ major, K. 282/189g, (1774) is a piano sonata in three movements: A typical performance takes about 12 minutes. Mozart wrote the work down during a visit to Munich for the production of La finta giardiniera from late 1774 to the beginning of the following March. The first movement is in sonata form. The second movement consists of two minuets, of which the first one is in the dominant key of B♭ major and the second one moves to the tonic (home) key of E♭ major, after which the first minuet in B♭ major is repeated, resulting in an A–B–A form overall. The third movement is also in sonata form and returns in the home key in E♭ major.

Wolfgang Amadeus Mozart's Piano Sonata No. 5 in G major, K. 283/189h, (1774) is a piano sonata in three movements: This sonata is part of the earliest group of sonatas that Mozart published in the mid-1770s. The first movement, in sonata form, is concise, with an economy of materials. The development section is a mere 18 measures long. The shorter length and moderate technical demands make it an ideal piece for early-advanced study and performance. A typical performance takes twelve to eighteen (Sviatoslav Richter) minutes. The work was written down during the visit Mozart paid to Munich for the production of his La finta giardiniera from late 1774 to the beginning of the following March.

Wolfgang Amadeus Mozart's Piano Sonata No. 6 in D major, K.. 284/205b, (1775) is a piano sonata in three movements: A typical performance takes about 20 to 25 minutes. This piano sonata is the last of the sonatas that Mozart composed in Munich. The piece is subtitled "Dürnitz", as it was written for Baron von Dürnitz, an amateur bassoonist and keyboard-player, who failed to pay for the work. The work was written during Mozart's stay in Munich from December 1774 to March 1775 for the production of La finta giardiniera. It is the only one of Mozart's six Munich piano sonatas to be published in his lifetime, ten years later. The autograph and the first edition of the sonata have numerous inconsistencies.

Wolfgang Amadeus Mozart's Piano Sonata No. 7 in C major, K. 309 (284b) (1777) is a piano sonata in three movements: A typical performance takes about 16 minutes. The work was composed during a journey to Mannheim and Paris in 1777–1778. In a letter to his father dated 24 October 1777, Mozart describes a concert where he played "a magnificent sonata in C major with a closing rondo, my own invention", suggesting that the sonata was completed by October 1777. The andante movement is a "portrait" of his pupil Rose Cannabich, the 13-year-old daughter of the Mannheim Kapellmeister Christian Cannabich. Upon reviewing a copy of the manuscript, Mozart's father Leopold wrote that it was "a strange composition. It has something in it of the 'rather artificial' Mannheim style, but so very little that your own good style is not spoilt."

Wolfgang Amadeus Mozart's Piano Sonata No. 8 in A minor, K. 310/300d, was written in 1778. The sonata is the first of only two Mozart piano sonatas in a minor key (the other being No. 14 in C minor, K. 457). It was composed in the summer of 1778 around the time of his mother's death, one of the most tragic times of his life. The autograph manuscript of the sonata is preserved in the Morgan Library & Museum.

Wolfgang Amadeus Mozart's Piano Sonata No. 9 in D major, K. 311 / 284c, was written on the composer's stay in Augsburg and Mannheim in November-December 1777, and is contemporaneous with his Sonata No. 7 in C Major K. 309 (Mozart wrote his Sonata K. 310 in the summer of the following year, in Paris). The three sonatas K. 309–311 were published as a set 'Opus IV' in about 1782, by Franz Joseph Heina in Paris. The work has three movements: A typical performance takes about 15 to 17 minutes. The first movement is in sonata form. Its first subject has a quasi-orchestral opening, and its second subject in the dominant key (A major) is quieter. The development section is almost entirely based on the last four bars of the exposition. The second movement has an episodic structure A–B–A–B–A–coda. The second theme's melody is gently decorated with syncopation, accompanied by broken chords in the left hand. This key is G major, the subdominant of D major. Lastly, the most technically demanding movement of the three is a sonata rondo, with a short central episode in B minor (the main key's relative minor). A slow cadenza-like passage containing a rapid ascending chromatic scale leads back to the first theme. In this passage the beginnings of the main theme of the famous second movement of the Piano Concerto No. 21 in C Major, K. 467, can be heard emerging, 8 years before he wrote it in 1785.

Wolfgang Amadeus Mozart (1756–1791) was a prolific and influential composer of the Classical period who wrote in many genres. Perhaps his best-admired works can be found within the categories of operas, piano concertos, piano sonatas, symphonies, string quartets, and string quintets. Mozart also wrote many violin sonatas; other forms of chamber music; violin concertos, and other concertos for one or more solo instruments; masses, and other religious music; organ music; masonic music; and numerous dances, marches, divertimenti, serenades, and other forms of light entertainment.

The Well-Tempered Clavier, BWV 846–893, consists of two sets of preludes and fugues in all 24 major and minor keys for keyboard by Johann Sebastian Bach. In the composer's time clavier referred to a variety of keyboard instruments, namely the harpsichord, the clavichord and the organ (which operates using air instead of strings), but not excluding the regal and the then newly-invented pianoforte. The modern German spelling for the collection is Das wohltemperierte Klavier (WTK; German pronunciation: [das ˌvoːlˌtɛmpəˈʁiːɐ̯tə klaˈviːɐ̯]). Bach gave the title Das Wohltemperirte Clavier to a book of preludes and fugues in all 24 keys, major and minor, dated 1722, composed "for the profit and use of musical youth desirous of learning, and especially for the pastime of those already skilled in this study". 20 years later, Bach compiled a second book of the same kind (24 pairs of preludes and fugues), which became known as The Well-Tempered Clavier, Part Two (in German: Zweyter Theil, modern spelling: Zweiter Teil). Modern editions usually refer to both parts as The Well-Tempered Clavier, Book 1 (WTC 1) and The Well-Tempered Clavier, Book 2 (WTC 2), respectively. The collection is generally regarded as one of the most important works in the history of classical music.

Major/minor compositions are musical compositions that begin in a major key and end in a minor key (generally the parallel minor), specifying the keynote (as C major/minor). This is a very unusual form in tonal music, although examples became more common in the nineteenth century. There are far fewer major/minor compositions than minor/major ones (the latter category of which includes, but is not limited to, all minor-key works that end with a Picardy third, as well as many Classical- and Romantic-period symphonies, concertos, sonatas and chamber works, and individual movements thereof.) The major/minor compositions in the following lists do not necessarily end with a minor chord; a final passage in minor ending with a sonority that fails to re-establish the major mode (for example, an open octave or fifth) is sufficient. Works falling into the following categories are excluded: Compositions that would be major/minor but for a final Picardy third stipulated by the composer, such as Bach's Darzu ist erschienen der Sohn Gottes, BWV 40, Francis Poulenc's Vinea mea electa from Quatre motets pour un temps de pénitence (FP 97), or Felix Mendelssohn's Piano Sextet, Op. 110; Compositions that would be major/minor, but end inconclusively on the major dominant of the final minor key, e.g. Nos. 2 and 9 of Robert Schumann's Kerner cycle, Op. 35, or Schumann's Die Nonne, Op. 49 No. 3; Compositions in which the beginning only hints at a possible reading of a major key without really establishing it, such as the Brahms Clarinet Quintet, Haydn's two string quartets, Op. 33 No. 1 and Op. 64 No. 2, C. P. E. Bach's Piano Sonata, Wq. 55/3, or the first movement of Alkan's Grande sonate 'Les quatre âges' (all of which are in B minor, but start with the possibility of D major); Compositions in which the opening major chord merely serves a function (e.g. dominant or Neapolitan) in the ensuing minor key, without being tonicized in its own right, such as Saint-Saëns' Danse macabre or Chopin's first Ballade; Compositions that are only incidentally major/minor due to being unfinished, without any indication that the composer intended them to be major/minor, such as Schubert's Piano Sonata in C, D. 840 or Haydn's String Quartet in D minor, Op. 103; Frequently performed portions of a larger work consisting of what is technically two separate movements, if the first of these finishes clearly on the tonic (and thus doesn't require continuation), such as the opening pair of movements in Beethoven's Piano Sonata Op. 109 (connected by an attacca); Entire extended works as song cycles, ballets, operas and oratorios that finish in a different tonic than the starting one, unless the two keys carry clear extramusical or programmatic connotions within the work (an explanation of which must accompany any such listings below).

The Rondo in A minor, K. 511, is a work for solo piano by Wolfgang Amadeus Mozart, composed and published in 1787. The work's theme contains the first eight notes of the ascending chromatic scale, from A to E.

The Russian and American classical virtuoso pianist Vladimir Horowitz was a recording artist for over 60 years, beginning in 1926 on a piano roll system for Welte-Mignon, then with audio recordings, starting in 1928 for the Victor Talking Machine Company, later RCA Victor. Horowitz continued to record for a variety of record labels throughout his life. Between 1962 and 1973, he recorded for Columbia Masterworks In 1975, he returned to RCA, with which he recorded a series of live recitals. For the last years of his life, between 1985 and 1989, Horowitz recorded for Deutsche Grammophon. His final recording, with Sony Classical, was completed in November 1989, four days before his death. This final recording consisted of repertoire that he had never previously recorded. His discography contains numerous albums and compilations of works by a variety of composers. Horowitz has also appeared in several video items, most of which were produced in the later years of his life.

A minor is a minor scale based on A, B, C, D, E, F, and G. Its key signature has no flats or sharps. Its relative major is C major and its parallel major is A major. The A natural minor scale is: Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The A harmonic minor and melodic minor scales are:

The Sonata in C major for piano four-hands, K. 521, is a piano sonata in three movements composed by Wolfgang Amadeus Mozart in 1787. It was his last complete piano duet sonata for one piano, four hands. This sonata consists of three movements: Allegro, Andante and Allegretto. The autograph manuscript of the sonata is preserved in the Fitzwilliam Museum, Cambridge.

Wolfgang Amadeus Mozart (1756–1791) was a prolific and influential composer of the Classical period who wrote in many genres. Perhaps his best-admired works can be found within the categories of operas, piano concertos, piano sonatas, symphonies, string quartets, and string quintets. Mozart also wrote many violin sonatas; other forms of chamber music; violin concertos, and other concertos for one or more solo instruments; masses, and other religious music; organ music; masonic music; and numerous dances, marches, divertimenti, serenades, and other forms of light entertainment.

The Sonata for Two Pianos in D major, K. 448 (375a), is a work composed by Wolfgang Amadeus Mozart in 1781, when he was 25. It is written in sonata-allegro form, with three movements. The sonata was composed for a performance he would give with fellow pianist Josepha Auernhammer. Mozart composed this in the galant style, with interlocking melodies and simultaneous cadences. This is one of his few compositions written for two pianos. The autograph manuscript of the sonata is preserved in Veste Coburg.

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.

Many classical and later composers have written compositions in the form of variations on a theme by another composer. This is an incomplete list of such works, sorted by the name of the original composer. The list does not include variations written on composers' own or original themes, or on folk, traditional or anonymous melodies. Many of these works are called simply "Variations on a Theme of/by ...". Other works, which often involve substantial development or transformation of the base material, may have more fanciful titles such as Caprice, Fantasy, Paraphrase, Reminiscences, Rhapsody, etc. These other types of treatments are not listed here unless there is evidence that they include variations on a theme.

In music, variation is a formal technique where material is repeated in an altered form. The changes may involve melody, rhythm, harmony, counterpoint, timbre, orchestration or any combination of these. Variation is often contrasted with musical development, which is a slightly different means to the same end. Variation depends upon one type of presentation at a time, while development is carried out upon portions of material treated in many different presentations and combinations at a time.

Twelve Variations on "Ah vous dirai-je, Maman", K. 265/300e, is a piano composition by Wolfgang Amadeus Mozart, composed when he was around 25 years old (1781 or 1782). This piece consists of twelve variations on the French folk song "Ah! vous dirai-je, maman". The French melody first appeared in 1761, and has been used for many children's songs, such as "Twinkle, Twinkle, Little Star", "Baa, Baa, Black Sheep", and the "Alphabet Song".

Wolfgang Amadeus Mozart (1756–1791) had a powerful influence on the works of Ludwig van Beethoven (1770–1827). Beethoven held Mozart in high regard. Some of his music recalls Mozart's; he composed several variations on Mozart's themes and he modeled a number of his compositions on those of the older composer. Whether the two men ever actually met remains a matter of speculation among scholars.

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".

Eight Variations in F major on "Ein Weib ist das herrlichste Ding", K. 613, is a set of theme and variations for piano by composer Wolfgang Amadeus Mozart. Composed in 1791, it is the last set of theme and variations for piano ever composed by Mozart.

In music, a two hundred fifty-sixth note, or occasionally demisemihemidemisemiquaver (British), is a note played for 1⁄256 of the duration of a whole note. It lasts half as long as a hundred twenty-eighth note and takes up one quarter of the length of a sixty-fourth note. In musical notation it has a total of six flags or beams. A single 256th note is always stemmed with flags, while two or more are usually beamed in groups. Notes this short are very rare in printed music, but not unknown. They are principally used for brief, rapid sections in slow movements. For example, they occur in some editions of the second movement (Largo) of Beethoven's Third Piano Concerto (Op. 37) (1800), to notate rapid scales. Another example is in Mozart's Variations on "Je suis Lindor" (1778), where four of them are used in the slow (molto adagio) eleventh variation. A further example occurs (Grave.Adagio non troppo) in Jan Ladislav Dussek's (1760–1812) Fifth Piano Sonata, Op. 10 No. 2. They also occur (Largo) in Vivaldi's (1678–1741) Concerto, RV 444, and in bar 15 of François Couperin's Second Prelude from L'art de toucher le clavecin (1716).

Twelve Variations on "La belle Françoise" (German: Zwölf Variationen über "La belle Françoise") in E-flat major, K. 353/300f, is a set of theme and variations composed for piano by Wolfgang Amadeus Mozart. Written after the popular French tune "La belle Françoise", it was presumably completed when Mozart was 22 years old.
