Johann Sebastian Bach
Johann Sebastian Bach was a German composer, organist, harpsichordist, violist, and violinist whose sacred and secular works for choir, orchestra, and solo instruments drew together the strands of the Baroque period and brought it to its ultimate maturity...

 (1685–1750). It was most likely started at the beginning of the 1740s, if not earlier. The first known surviving version, which contained 12 fugue

: Die Kunst der Fuga. Bach's second version was published in 1751 after his death. It contains 14 fugues and 4 canons. "The governing idea of the work", as the eminent Bach specialist Christoph Wolff put it, is "an exploration in depth of the contrapuntal possibilities inherent in a single musical subject."

Each of the 14 fugues except the final unfinished one use the same deceptively simple subject in D minor

Structure

In the 1751 printed edition, the various movements are roughly arranged by increasing order of sophistication of the contrapuntal devices used. The Arabic number in the title indicates the number of voices in the fugue, with the exception of the last one, where a 3 Soggetti means "with 3 subjects":

Simple fugues:
1. Contrapunctus I, and
2. Contrapunctus II: Simple monothematic 4-voice fugues on main theme, accompanied by a 'French' style dotted rhythm motif.
3. Contrapunctus III, and
4. Contrapunctus IV: Simple monothematic 4-voice fugues on inversion
Inversion (music)

 of main theme, i.e. the theme is "turned upside down":

Counter-fugues, in which a variation of the main subject is used in both regular and inverted form:
5. Contrapunctus V: Has many stretto

 entries, as do Contrapuncti VI and VII.
6. Contrapunctus VI, a 4 in Stylo Francese: This adds both forms of the theme in diminution (halving note lengths), with little rising and descending clusters of semiquavers in one voice answered or punctuated by similar groups in demisemiquavers in another, against sustained notes in the accompanying voices. The dotted rhythm, enhanced by these little rising and descending groups, suggests what is called "French style" in Bach's day, hence the name Stylo Francese.
7. Contrapunctus VII, a 4 per Augmentationem et Diminutionem: Uses augmented

  versions of the main subject and its inversion.

Double and triple fugues, with two and three subjects respectively:
8. Contrapunctus VIII, a 3: Triple fugue.
9. Contrapunctus IX, a 4 alla Duodecima: Double fugue

10. Contrapunctus X, a 4 alla Decima: Double fugue.
11. Contrapunctus XI, a 4: Triple fugue.

Mirror fugues, in which the complete score can be inverted without loss of musicality:
12. Contrapunctus XII, a 4: The rectus (normal) and inversus (upside-down) versions are generally played back to back.
13. Contrapunctus XIII, a 3: The second mirror fugue in 3 voices, also a counter-fugue.

Canons, labeled by interval and technique:
14. Canon per Augmentationem in Contrario Motu: Augmented canon in inverted motion.
15. Canon alla Ottava: Canon at the Octave. The two imitating voices are separated by an octave.
16. Canon alla Decima in Contrapunto alla Terza: Canon at the tenth, counterpoint at the third.
17. Canon alla Duodecima in Contrapunto alla Quinta: Canon at the twelfth, counterpoint at the fifth.

An arrangement of Contrapunctus XIII, see below.
18. Fuga a 2 (rectus), and Alio modo Fuga a 2 (inversus)

Unfinished quadruple fugue:
19. Fuga a 3 Soggetti (Contrapunctus XIV): 4-voice triple, possibly quadruple, fugue, the third subject of which is based on the BACH motif
BACH motif
In music, the BACH motif is the motif, a succession of notes important or characteristic to a piece, B flat, A, C, B natural. In German musical nomenclature, in which the note B natural is written as H and the B flat as B, it forms Johann Sebastian Bach's family name...

, B - A – C – B ('H' in German letter notation).

Sources of the work

The order of the fugues and canons has been debated, especially as there are differences between the manuscript and the printed editions appearing immediately after Bach's death. Also musical reasons have been invoked to propose different orders for later publications and/or the execution of the work, e.g. by Wolfgang Graeser in 1927, who also published his own "completion" of the final Contrapunctus XIV.

The 1751 printed edition contained — apart from a high number of errors and other flaws — a four-part version of Contrapunctus XIII, arranged to be played on two keyboards (rectus BWV 1080/18,1 and inversus BWV 1080/18,2). It is however doubtful whether the printed indication "a 2 Clav.", and the fourth added voice, that is not mirrored according to Bach's usual practice, derive from him, or from his son(s) that supervised this first edition.

The engraving of the copper plates for the printed edition would however have started shortly before the composer's death, according to contemporary sources, but it is unlikely that Bach had any real supervision in that preparation of the printed edition, due to his illness at the time.

The first printed edition also includes an unrelated work as a kind of "encore", the chorale prelude Vor deinen Thron tret Ich hiermit (Herewith I come before Thy Throne), BWV

 668a, which Bach is said to have dictated on his deathbed.

A 1742 fair copy manuscript contains Contrapuncti I–III, V–IX, and XI–XIII, plus the octave and augmented canons and an earlier version of Contrapunctus X.

Instrumentation

Manuscript copies of the Art of Fugue, as well as the first printed edition, use open scoring, where each voice is written on its own staff. This has led to the assumption that the Art of Fugue was an intellectual exercise, meant to be studied and not heard. However, musicologists today, such as Gustav Leonhardt
Gustav Leonhardt
Gustav Leonhardt is a highly renowned Dutch keyboard player, conductor, musicologist, teacher and editor. Leonhardt has been a leading figure in the movement to perform music on period instruments...

, agree that the Art of Fugue was probably intended to be played on a keyboard instrument. Leonhardt's arguments included the following:
  1. It was common practice in the 17th and early 18th centuries to publish keyboard pieces in open score, especially those that are contrapuntally complex. Examples include Frescobaldi
    Girolamo Frescobaldi
    Girolamo Frescobaldi was a musician from Ferrara, one of the most important composers of keyboard music in the late Renaissance and early Baroque periods. A child prodigy, Frescobaldi studied under Luzzasco Luzzaschi in Ferrara, but was influenced by a large number of composers, including Ascanio...

  2. The range of none of the ensemble or orchestral instruments of the period corresponds to any of the ranges of the voices in The Art of Fugue. Furthermore, none of the melodic shapes that characterize Bach's ensemble writing are found in the work, and there is no basso continuo.
  3. The fugue types used are reminiscent of the types in The Well-Tempered Clavier
    The Well-Tempered Clavier
    The Well-Tempered Clavier , BWV 846–893, is a collection of solo keyboard music composed by Johann Sebastian Bach...

    , rather than Bach's ensemble fugues; Leonhardt also shows an "optical" resemblance between the fugues of the two collections, and points out other stylistic similarities between them.
  4. Finally, since the bass voice in The Art of Fugue occasionally rises above the tenor, and the tenor becomes the "real" bass, Leonhardt deduces that the bass part was not meant to be doubled at 16-foot pitch, thus eliminating the pipe organ as the intended instrument, leaving the harpsichord as the most logical choice.

The fact that it is playable on a keyboard at all is evidence for some that this was Bach's intended instrument, as it is not possible to play most of his ensemble pieces on a keyboard instrument.

The unfinished fugue

Contrapunctus XIV breaks off abruptly in the middle of the third section at bar 239. The autograph carries a note in the handwriting of Bach's son Carl Philipp Emanuel Bach

 saying "Über dieser Fuge, wo der Name B A C H im Contrasubject angebracht worden, ist der Verfasser gestorben." ("At the point where the composer introduces the name BACH [for which the English notation would be B-A-C-B] in the countersubject to this fugue, the composer died.") However, modern scholarship disputes this version, in particular because the musical notes are indisputably in Bach's own hand, written in a time before his deteriorating vision led to erratic handwriting, probably 1748–1749.

Many scholars, including Gustav Nottebohm

, have argued that the piece was intended to be a quadruple fugue, with the opening theme of Contrapunctus I to be introduced as the fourth subject. The title Fuga a 3 soggetti, in Italian rather than Latin, was not given by the composer but by CPE Bach

, and Bach's Obituary actually makes mention of "a draft for a fugue that was to contain four themes in four voices". The combination of all four themes would bring the entire work to a fitting climax. Wolff also suspected that Bach might have finished the fugue on a lost page, called "fragment X" by him, on which the composer attempted to work out the counterpoint between the four subjects.

A number of musicians and musicologists have conjectured completions of Contrapunctus XIV, notably music theoretician Hugo Riemann

In 2007, New Zealand organist and conductor Indra Hughes completed a doctoral thesis about the unfinished ending of Contrapunctus XIV, proposing that the work was left unfinished not because Bach died, but as a deliberate choice by Bach to encourage independent efforts at a completion.

's book Gödel, Escher, Bach
Gödel, Escher, Bach
Gödel, Escher, Bach: An Eternal Golden Braid is a book by Douglas Hofstadter, described by his publishing company as "a metaphorical fugue on minds and machines in the spirit of Lewis Carroll"....

discusses the unfinished fugue and Bach's supposed death during composition as a tongue-in-cheek illustration of Austrian logician Kurt Gödel's first incompleteness theorem. To be more specific, the idea in that theorem is that the very power of a "sufficiently powerful" formal mathematical system can be exploited to "undermine" the system, by leading to statements that assert such things as "I cannot be proven in this system". Because of this twisty kind of self-reference, such assertions are true but unprovable. In Hofstadter's discussion, Bach's great compositional talent is used as a metaphor for a "sufficiently powerful" formal system; however, Bach's insertion of his own name "in code" into the fugue is not, even metaphorically, a case of Gödelian self-reference; and Bach's failure to finish his self-referential fugue serves as a metaphor for the unprovability of the Gödelian assertion, and thus for the incompleteness of the formal system.

A book entitled "Bach: Essays on His Life and Music" includes an article about the unfinished fugue, stating that Bach never intended to write the rest of the fugue on the last sheet of music paper used for the fugue because of the unalignment of the bottom staves. It also says that because of the above-mentioned reason, Bach wrote the rest of the fugue on another sheet of music paper, called "fragment x" that would have completed, or almost completed, the fugue. However, even if there is a fragment x, it has been lost.

The permutation matrix

In 1991 a theory was published by Zoltán Göncz

 answering the question of how Bach planned the appearance of the fourth subject, the main subject of the cycle:

In the course of the exposition of the first three subjects (first subject: mm. 1–21, second subject: mm. 114–141, third subject: mm. 193–207), Bach applied a serial sequence of voice entries decided in advance, by which he determined the space and time parameters of the subject entries. The superimposition of the three exposition matrices foreshadows, and develops as a negative, the sequence of the voice entries of the fourth subject. The copying of the four subjects onto each other displays a characteristic construction of Bach's oeuvre occurring mainly in the vocal fugues: that of the permutation fugue.



However paradoxical, it follows from the logic of composing a quadruple fugue that the combinations joining all four subjects (i.e. those combinations which appear last when performing the work) were already completed in the very first stage of composition, because the possibility of overlapping the four subjects (1 + 2 + 3 + 4) is the sine qua non
Sine qua non
Sine qua non or condicio sine qua non refers to an indispensable and essential action, condition, or ingredient...

of writing a quadruple fugue. The process of composition does not proceed in a linear way from the beginning, but with all four parts in view.

One of the striking features of Contrapunctus XIV is that in this movement Bach applied the stretto

 of whole expositions, layering the first two expositions atop each other prior to introducing the third subject. In the exposition of the first three subjects he "programmed" the later permutation stretti, then applied the expositions as "programs", "algorithms". The permutation matrix, apart from originating authentically with Bach, can be proved to have been ready at the time of the genesis of the work (that is, earlier than the surviving section).

The discovery of the permutation matrix was one of the most essential requirements for achieving a reconstruction of Contrapunctus XIV which might approach the original form planned by Bach.

The society was concerned with the union of music, philosophy, mathematics and science in Pythagorean theory, and required each member to contribute a practical work in demonstration of this approach, for which Bach produced his Canonic Variations on "Vom Himmel hoch da komm' ich her"

Against the theory is Bach's apparent indifference to the Society in its early years, and his hesitancy in joining it. The Society had in fact attempted to establish principles for the writing of cantatas which were not in line with his own approach. Since any musical structure was susceptible to Mizler's Pythagorean analysis, the case for any specific precedent influence on The Art of Fugue remains conjectural.
