Music written in all major and/or minor keys
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).
Well-known 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 Two Preludes through all twelve 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).

Sets that cover all 24 keys
Most well-known sets
Some of the best-known examples of works covering all 24 major and minor keys are:
- Johann Sebastian Bach: The Well-Tempered Clavier, Books I and II (1722 and 1742) – two separate sets of 24 preludes and fugues, together known as "the 48".
- Frédéric Chopin: 24 Preludes, Op. 28 (1835–39)
- Charles-Valentin Alkan: 25 Preludes, Op. 31 (1847) – 24 etudes in all the major and minor keys, Op. 35 and 39 (1848 and 1857)
- Alexander Scriabin: 24 Preludes, Op. 11 (1893–95) – All told, Scriabin wrote a total of 90 preludes for piano (50 in major keys, 31 in minor keys, and 9 in indeterminate keys). These contained only one complete set of preludes in all 24 major and minor keys, but he seems to have started another set (spread over 4 opus numbers) before the key relationships broke down.
- Sergei Rachmaninoff: 24 Preludes, Opp. 3/2, 23, and 32 (1892, 1901–03, and 1910) – it seems that Rachmaninoff did not originally set out to write a set of works in all 24 keys
- Paul Hindemith: Ludus Tonalis (1942) – twelve keys
- Dmitri Shostakovich: 24 Preludes and Fugues, Op. 87 (1950–51) – Shostakovich also wrote a separate set of 24 Preludes, Op. 34 in 1933.
- Franz Liszt: Transcendental Études, S. 139 (1826–52) – It covers the natural and flat keys (the keys with flat signatures) only. Liszt originally planned to write the full suite of 24 études, but apparently abandoned this plan. In 1897–1905, Sergei Lyapunov wrote his 12 Études d'exécution transcendante, Op. 11, which covers the remaining sharp keys and is dedicated to Liszt's memory.
Composers who wrote multiple sets
A number of composers have not been content with just one set of works covering all the keys of the scale. For instance, Niels Viggo Bentzon wrote no fewer than 14 complete sets of 24 Preludes and Fugues, a total of 336 pieces in this genre alone. Others who have written more than one set include:
- Charles-Valentin Alkan: 25 Preludes; Esquisses; 24 Études (published as separate sets of major-key and minor-key études) – Alkan seems to have also started a fourth set: the 11 grands préludes et un transcription du Messie de Hændel, Op. 66, are a set of 12 pieces that cover all the keys that have one to six flats (although Alkan replaces G♭ major with its enharmonic equivalent using sharps, F♯ major). However, this set was never completed.
- Lera Auerbach: 24 Preludes (piano); 24 Preludes (violin and piano); 24 Preludes (cello and piano)
- Johann Sebastian Bach: The Well-Tempered Clavier, Books I and II (1722 and 1742) – Though separated by 20 years, they are usually considered a single work and referred to as "the 48".
- David Cope: 48 Preludes and Fugues
- Carl Czerny: At least three sets, piano exercises (Opp. 152, 380) and 24 preludes and fugues ("Der Pianist im klassischen Style: 48 Präludien und Fugen in allen 24 Dur- und Moll-Tonarten als Vorstudien des volkommenen Vortrags aller klassischen Tonwerke"[a], Op. 856)
- Johann Nepomuk Hummel: 24 Preludes; 24 Études
- Friedrich Kalkbrenner: 24 Études; 24 Preludes
- Nikolai Kapustin: 24 Preludes in Jazz Style; 24 Preludes and Fugues
- Joseph Christoph Kessler: 24 Études; 24 Preludes
- Craig Sellar Lang: Two books of 24 preludes and fugues
- Trygve Madsen: 24 Preludes Op. 20; 24 Preludes and Fugues Op. 101
- Jaan Rääts: 24 Marginalia; 24 Estonian Preludes
- Igor Rekhin (b. 1941 in Tambov, Russia): 24 Preludes and Fugues for guitar; 24 Caprices for solo cello
- Josef Rheinberger: 24 Fughettas, Op. 123 – He also intended to compose 24 organ sonatas, but died having completed only 20.
- Christian Heinrich Rinck: 30 Preludes; Exercises in all the keys
- Dmitri Shostakovich: 24 Preludes, Op. 34; 24 Preludes and Fugues, Op. 87 – He also set out to write 24 string quartets all in different keys, but completed only 15 of them.
- Sir Charles Villiers Stanford: 2 sets of 24 Preludes, Opp. 163, 179
- Louis Vierne: 24 Pièces en style libre; 24 Pièces de fantaisie
- Vsevolod Zaderatsky: 24 Preludes; 24 Preludes and Fugues (written in prison, without a piano, on telegraph forms)
Single pieces that modulate through many keys
Ludwig van Beethoven wrote 2 Preludes through all 12 Major Keys, Op. 39 for piano (1789).[b] These two preludes each progressively traverse the 12 major keys. In Prelude No. 1, each key occupies from 2 to 26 bars. The keys of C♯ and D♭, which are enharmonically equivalent, are both represented. C major both opens and closes the set. In Prelude No. 2, the cycle of keys appears twice; in the first cycle, the number of bars per key ranges from 1 to 8; in the second half, after C every new key signature lasts for only one bar; the cycle concludes with 15 bars of C major. There is no evidence that Beethoven intended to write similar sets in the 12 minor keys.
Giovanni Battista Vitali (1632–1692) included in Artificii musicali, Op. 13 (1689) a passacaglia which modulates through eight major keys (out of twelve) from E♭ major to E major through the cycle of fifths.
Fugue No. 8 from Anton Reicha's Trente six Fugues pour le Piano-Forté composées d'après un nouveau systême (subtitled Cercle harmonique) modulates through all keys.
The rondo theme of Darius Milhaud's Le bœuf sur le toit is played fifteen times in all 12 major keys (twice in A major and thrice in the tonic, C major). It also passes through every minor key, with the exceptions of E minor and B minor.
Works covering all eight church modes
Charles-Valentin Alkan composed Petits préludes sur les huit gammes du plain-chant, for organ (1859, no opus number), a sequence of eight organ preludes covering each of the church modes.
Other sets of 24 pieces
Not all sets of 24 pieces belong in this category. For example, there was no intention in Niccolò Paganini's 24 Caprices for solo violin, Claude Debussy's 24 Préludes for piano, or Pavel Zemek Novak's 24 Preludes and Fugues for piano to cover all the keys. (Paganini may not have been aware of Pierre Rode's 24 Caprices for violin, which did span the 24 keys and were written almost as the same time as Paganini's.)
Chopin's 24 Études, Opp. 10 & 25 might have originally been planned to be in all 24 keys. In fact, apart from Nos. 7 and 8, the first series (Op. 10) is made of couples of études in a major key and its parallel minor (the major key either preceding the minor key or following it) with none of the tonalities occurring twice (except for C major, which appears in No. 1 and then in the only couple which is not major-minor, i.e. Nos. 7 and 8). But in the second series (Op. 25) this tonal scheme gets more and more loose. It is still possible to see connections on a tonal basis between the couples of études in Op. 25, but they are not based on one principle (e.g. Nos. 3 and 4 in F major – A minor, two tonalities which Chopin likes to put together very often, as in his second Ballade).
One might suppose that Chopin considered writing the études in all the tonalities but eventually came to the conclusion that it wasn't practical and turned back to it later, for the 24 Preludes, Op. 28. The fact that the first étude of Op. 10 is made of arpeggios in C major draws a connection to Bach's first book of The Well-Tempered Clavier and makes it clear that Chopin had the tradition on his mind.[original research?]
Bach and his precursors
Johann Sebastian Bach's The Well-Tempered Clavier, two complete sets of 24 Preludes and Fugues written for keyboard in 1722 and 1742, and often known as "the 48", is generally considered the greatest example of music traversing all 24 keys. Many later composers clearly modelled their sets on Bach's, including the order of the keys.
It was long believed that Bach had taken the title The Well-Tempered Clavier from a similarly-named set of 24 Preludes and Fugues in all the keys, for which a manuscript dated 1689 was found in the library of the Brussels Conservatoire. It was later shown that this was the work of a composer who was not even born by 1689: Bernhard Christian Weber (1712–1758). In fact, the work was written in 1745–50 in imitation of Bach's example. While Bach can safely claim the title The Well-Tempered Clavier, he was not the earliest composer to write sets of pieces in all the keys:
As early as 1567, Giacomo Gorzanis (c.1520–c.1577) wrote a cycle of 24 passamezzo–saltarello pairs. In 1584, Vincenzo Galilei, father of Galileo Galilei, wrote a Codex of pieces illustrating the use of all 24 major and minor keys.
In 1640, Angelo Michele Bartolotti wrote Libro primo di chitarra spagnola, a cycle of passacaglias that moves through all 24 major and minor keys according to the circle of fifths. Also in 1640, Antonio Carbonchi wrote Sonate di chitarra spagnola con intavolatura franzese for guitar.
In 1702, Johann Caspar Ferdinand Fischer wrote a cycle of 20 organ pieces all in different keys in his Ariadne musica. These included E major as well as E in Phrygian mode and again in Dorian mode, but not E minor per se. They also excluded C♯/D♭ major, D♯/E♭ minor, F♯/G♭ major, G♯/A♭ minor, and A♯/B♭ minor. Bach modelled the sequence of his 48 Preludes on Fischer's example.
In 1735, between Bach's two sets, Johann Christian Schickhardt wrote his L'alphabet de la musique, Op. 30, which contained 24 sonatas for flute, violin, or recorder in all keys. In 1749, the year before Bach's death, Johann Gottlieb Goldberg, the inspiration for J.S. Bach's Goldberg Variations, wrote his own 24 polonaises for keyboard, one in each of the major and minor keys. Other examples include works by John Wilson (1595–1674), Daniel Croner (1682), Christoph Graupner (1718), Johann Mattheson (1719), Friedrich Suppig (1722), and Johann David Heinichen (1683–1729).

In theory,[y] there are 31 possible note names[z] and, taking each as the tonic of one major and one minor key, 62 key names. But 32 of those keys have uncommon signatures which contain double flats or double sharps, so in practice the choice of key name is restricted to the 30 keys whose signatures have no double flats or double sharps. Keys with 6 flats and 6 sharps,[aa] with 7 flats and 5 sharps[ab] and with 5 flats and 7 sharps[ac] are enharmonic to one another. Composers will, in most (though not all) cases, choose only one key from each enharmonic pair. But there are also cases of sets covering all 30 keys, which, in other words, include all enharmonic variants.
The table below outlines the choices made in the various collections listed here. The keys are in the order that J.S. Bach used.
|1||C major||No sharps or flats|
|2||C minor||3 flats|
|3||Either C♯ major||7 sharps||Bach and Alkan chose C♯ major, but most composers have preferred D♭ major|
|or D♭ major||5 flats|
|4||C♯ minor||4 sharps|
|5||D major||2 sharps|
|6||D minor||1 flat|
|7||E♭ major||3 flats|
|8||Either D♯ minor||6 sharps||Most composers of sets of 24 pieces have chosen E♭ minor over D♯ minor. Bach, Lyapunov and Ponce used D♯, but most composers have preferred E♭. The first use of D♯ minor was in Bach's The Well-Tempered Clavier, in Fugue No. 8 from Book 1 (although its corresponding Prelude was written in E♭ minor), while D♯ minor was used for both the Prelude and the Fugue in Book 2. Another is in Lyapunov's Étude d'execution transcendante No. 2, subtitled "Ronde des Fantômes"|
|or E♭ minor||6 flats|
|9||E major||4 sharps|
|10||E minor||1 sharp|
|11||F major||1 flat|
|12||F minor||4 flats|
|13||Either F♯ major||6 sharps||F♯ major was the choice of Bach, Hummel, Chopin, Heller, Busoni, Lyapunov, Arensky, Blumenfeld, Ponce and Shostakovich. |
G♭ major was preferred by Alkan, Rachmaninoff, Scriabin, Shchedrin and Winding.
|or G♭ major||6 flats|
|14||F♯ minor||3 sharps|
|15||G major||1 sharp|
|16||G minor||2 flats|
|17||A♭ major||4 flats|
|18||Either G♯ minor||5 sharps||Alkan wrote a piece in A♭ minor, and Brahms a fugue in this key, but most composers have preferred G♯ minor.|
|or A♭ minor||7 flats|
|19||A major||3 sharps|
|20||A minor||No sharps or flats|
|21||B♭ major||2 flats|
|22||Either B♭ minor||5 flats||No well-known sets of 24 pieces include A♯ minor. Two examples are from Bartolomeo Campagnoli's 30 Preludes for violin, and Christian Heinrich Rinck's 30 Préludes from his Practical Organ School, Op. 55, published before 1821.|
|or A♯ minor||7 sharps|
|23||Either B major||5 sharps||No well-known sets of 24 pieces include C♭ major. While C♭ major is sometimes used in compositions (particularly for the harp, which is especially suited to this key), it is not generally considered one of the standard keys because it is enharmonically equivalent to B major. With its tonic note C♭ being in fact a white key, and its parallel minor having 10 flats, its usage is generally undesirable. It is very rare for a set of pieces covering all the keys to include a piece in C♭ major. C♭ major does appear in Campagnoli's and Rinck's works mentioned above, along with A♯ minor, but those collections include both members of all six enharmonically equivalent pairs.|
|or C♭ major||7 flats|
|24||B minor||2 sharps|
Order of keys in published works
The circle of fifths, whereby each major key is followed by its relative minor key, is a commonly used schema. Angelo Michele Bartolotti used this approach as early as 1640, and it was also adopted by such later composers as Rode, Hummel, Chopin, Heller, Busoni, Scriabin, Shostakovich, Kabalevsky and Kapustin.
Other composers derived their own schemas based on certain logical rationales. For example, in Alkan’s 25 Preludes, Op. 31, the sequence of keys moves alternately up a fourth and down a third.
- The number is 48 as preludes and fugues are counted separately
- C, G, D, A, E, B, F♯, C♯, D♭, A♭, E♭, B♭, F
- Arranged in a circle of fifths with major keys preceding the minor keys: C, G, D, A etc.; a, e, b ... d.
- Préludes et exercices: C, a, F, d, G, e, B♭, g, D, b, E♭, c, A, f♯, A♭, f, E, c♯, D♭, b♭, B, g♯, F♯, e♭; Grande Exercice: C, a, F, d, B♭, g, E♭, c, A♭, f, D♭, b♭, G♭, e♭, B, g♯, E, c♯, A, f♯, D, b, G, e
- Arranged in a circle of fifths, as alternating major and relative minor keys: C, a, G, e, D, b, A, f♯, E, c♯, B, g♯, F♯, e♭, D♭, b♭, A♭, f, E♭, c, B♭, g, F, d. Alexander Scriabin, Rodion Shchedrin et al. chose G♭ over F♯, but this does not affect the essential integrity of the scheme.
- C, a, G, e, D, b, A, f♯, E, c♯, B, g♯, F♯, d♯, C♯, a♯, F, d, B♭, g, E♭, c, A♭, f, D♭, b♭, G♭, e♭, C♭, a♭
- C, a, G, e, D, b, A, f♯, E, c♯, B, g♯, F♯, d♯, C♯, a♯, C♭, a♭, G♭, e♭, D♭, b♭, A♭, f, E♭, c, B♭, g, F, d
- A, D, G, C, F, B♭, E♭, A♭, C♯, G♭, B, E
- a, d, g, c, f, b♭, e♭, g♯, c♯, f♯, b, e
- C, a, F, d, B♭, g, E♭, c, A♭, f, D♭, b♭, G♭, e♭, B, a♭ (the prelude is headed "A♭ minor or G♯ minor"), E, c♯, A, f♯, D, b, G, e
- C, c, D♭, c♯ leading to D♭, D, d, E♭, e♭, E, e, F, f, F♯, f♯, G, g, A♭, g♯, A, a, B♭, b♭, B, b
- C, a, F, d, B♭, g, E♭, c, A♭, f, D♭, b♭, G♭, e♭, B, g♯, E, c♯, A, f♯, D, b, G, e, C
- C, e, G, b, D, f♯, A, c♯, E, g♯, B, e♭, F♯, b♭, D♭, f, A♭, c, E♭, g, B♭, d, F, a, C
- C, c, D♭, c♯, D, d, E♭, e♭, E, e, F, f, F♯, f♯, G, g, A♭, g♯, A, a, B♭, b♭, B, b, C; Alexander Wunderer and York Bowen chose G♭ over F♯; Valery Zhelobinsky notated his B♭ minor prelude with a 6-flat key signature (ostensibly E♭ minor), using accidentals to achieve the correct tonality.
- e, f♯, E, c♯, G, g, D, b, g♯, A♭, C, a, B, d, B♭, F, f, A, F♯, e♭, c, E♭, b♭, D♭
- c♯, f♯, B♭, d, D, g, E♭, c, A♭, e♭, G♭, C, b♭, E, e, G, f, F, a, A, b, B, g♯, D♭
- C, a, d, F, g, B♭, c, e, G, b, D♭, b♭, A♭, f, g♯, c♯, e♭, D, E♭, F♯, A, B, f♯, E
- C, G, F, A, E, E♭, A♭, D, B♭, D♭, B, F♯
- g, D, a, E, b, F♯, c♯, A♭, e♭, B♭, f, C, G, d, A, e, B, f♯, C♯, g♯, E♭, b♭, F, c
- a, e, b; c, g, d; e♭, b♭, f; f♯, c♯, a♭. The etudes are laid out in four groups of three keys following the ascending circle of fifths separated by a minor third.
- C, c, C♯, c♯, D, d, E♭, e♭, E, e, F, f, F♯, f♯, G, g, A♭, g♯, A, a, B♭, b♭, B, b
- There are 12 notes in the octave. Each of them can be the tonic of one major and one minor key.
- Note names which designate the same actual note in the 12 note octave such as G♯ and A♭.
- Keys whose tonics are enharmonic to one another such as F♯ major and G♭ major.
- If one restricts oneself to the note names used for the diatonic and chromatic tones of the 15 keys which use no double flats or double sharps in their signature.
- The seven notes A, B, C, D, E, F and G can be natural, flat or sharp. All notes except C and F can be double-flatted. All notes except B and E can be double-sharped. F and C occur only (first as chromatic tones) in keys with double flats in their key signature. B and E occur only (first as chromatic tones) in keys with double sharps in their key signature.
