Editing Fugue (section)

===20th century===
Twentieth-century composers brought fugue back to its position of prominence, realizing its uses in full instrumental works, its importance in development and introductory sections, and the developmental capabilities of fugal composition.<ref name="Graves-1962-p64"/>

The second movement of [[Maurice Ravel]]'s piano suite ''[[Le Tombeau de Couperin]]'' (1917) is a fugue that [[Roy Howat]] (200, p.&nbsp;88) describes as having "a subtle glint of jazz".<ref>Howat, R.

[[Béla Bartók]]'s ''[[Music for Strings, Percussion and Celesta]]'' (1936) opens with a slow fugue that [[Pierre Boulez]] (1986, pp.&nbsp;346–47) regards as "certainly the finest and most characteristic example of Bartók's subtle style... probably the most ''timeless'' of all Bartók's works – a fugue that unfolds like a fan to a point of maximum intensity and then closes, returning to the mysterious atmosphere of the opening."<ref>Boulez, P. (1986) ''Orientations''. London, Faber.</ref> The second movement of Bartók's [[Sonata for Solo Violin (Bartók)|Sonata for Solo Violin]] is a fugue, and the first movement of his [[Sonata for Two Pianos and Percussion]] contains a fugato.

''Schwanda the Bagpiper'' (Czech: Švanda dudák), written in 1926, an opera in two acts (five scenes), with music by Jaromír Weinberger, includes a ''Polka'' followed by a powerful ''Fugue'' based on the Polka theme.

[[Igor Stravinsky]] also incorporated fugues into his works, including the [[Symphony of Psalms]] and the [[Concerto in E-flat (Dumbarton Oaks)|Dumbarton Oaks]] concerto. Stravinsky recognized the compositional techniques of Bach, and in the second movement of his Symphony of Psalms (1930), he lays out a fugue that is much like that of the Baroque era.<ref>{{harvnb|Graves|1962|p=67}}</ref> It employs a double fugue with two distinct subjects, the first beginning in C and the second in E{{music|flat}}. Techniques such as stretto, sequencing, and the use of subject incipits are frequently heard in the movement. [[Dmitri Shostakovich]]'s [[24 Preludes and Fugues (Shostakovich)|24 Preludes and Fugues]] is the composer's homage to Bach's two volumes of [[The Well-Tempered Clavier]]. In the first movement of his [[Symphony No. 4 (Shostakovich)|Fourth Symphony]], starting at rehearsal mark 63, is a gigantic fugue in which the 20-bar subject (and tonal answer) consist entirely of semiquavers, played at the speed of quaver = 168.

[[Olivier Messiaen]], writing about his ''[[Vingt regards sur l'enfant-Jésus]]'' (1944) wrote of the sixth piece of that collection, "''Par Lui tout a été fait''" ("By Him were all things made"): {{Blockquote|It expresses the Creation of All Things: space, time, stars, planets&nbsp;– and the Countenance (or rather, the Thought) of God behind the flames and the seething&nbsp;– impossible even to speak of it, I have not attempted to describe it ... Instead, I have sheltered behind the form of the Fugue. Bach's ''[[Art of Fugue]]'' and the fugue from Beethoven's Opus 106 (the ''[[Hammerklavier sonata]]'') have nothing to do with the academic fugue. Like those great models, this one is an anti-scholastic fugue.<ref>Notes to ''Vingt Regards sur l'Enfant Jésus''. Translator not indicated. Erato Disques S.A. 4509-91705-2, 1993.

[[György Ligeti]] wrote a five-part double fugue{{Clarify|date=January 2016}}<!--Are "canon" and "fugue" just two different terms for the same thing? From this description, that would seem to be the case, and nowhere else in the article is a clear distinction made.--> for [[Requiem (Ligeti)|his ''Requiem'']]'s second movement, the Kyrie, in which each part (SMATB) is subdivided in four-voice "bundles" that make a [[canon (music)|canon]].{{Failed verification|date=January 2016}}<!--This is just a recording of the piece, which cannot verify anything about its construction.--> The melodic material in this fugue is totally [[Diatonic and chromatic|chromatic]], with [[melismatic]] (running) parts overlaid onto skipping intervals, and use of [[polyrhythm]] (multiple simultaneous subdivisions of the measure), blurring everything both harmonically and rhythmically so as to create an aural aggregate, thus highlighting the theoretical/aesthetic question of the next section as to whether fugue is a form or a texture.<ref>Eric Drott, "Lines, Masses, Micropolyphony: Ligeti's Kyrie and the 'Crisis of the Figure{{'"}}.

{{Blockquote|text=takes the logic of the fugal idea and creates something that's meticulously built on precise contrapuntal principles of imitation and fugality, but he expands them into a different region of musical experience. Ligeti doesn't want us to hear individual entries of the subject or any subject, or to allow us access to the labyrinth through listening in to individual lines… He creates instead a vastly dense texture of voices in his choir and orchestra, a huge stratified slab of terrifying visionary power. Yet this is music that's made with a fine craft and detail of a Swiss clock maker. Ligeti's so-called '[[Micropolyphony|micro-polyphony]]': the many voicedness of small intervals at small distances in time from one another is a kind of conjuring trick. At the micro level of the individual lines, and there are dozens and dozens of them in this music...there's an astonishing detail and finesse, but the overall macro effect is a huge overwhelming and singular experience.<ref>[[Tom Service|Service, Tom]].

[[Benjamin Britten]] used a fugue in the final part of ''[[The Young Person's Guide to the Orchestra]]'' (1946). The [[Henry Purcell]] theme is triumphantly cited at the end, making it a choral fugue.<ref>{{Cite web |url=https://goodmorningbritten.wordpress.com/2013/10/18/listening-to-britten-the-young-persons-guide-to-the-orchestra-op-34/ |title=Listening to Britten – the Young Person's Guide to the Orchestra, Op.34 |website=goodmorningbritten.wordpress.com |date=18 October 2013}}</ref>

Canadian pianist and musical thinker [[Glenn Gould]] composed ''[[So You Want to Write a Fugue?]]'', a full-scale fugue set to a text that cleverly explicates its own musical form.<ref>{{cite book |last=Bazzana|first=Kevin |title=Wondrous Strange: The Life and Art of Glenn Gould |url=https://archive.org/details/wondrousstrangel00bazz |url-access=registration |publisher=Oxford University Press |location=New York |year=2004 |isbn=0-19-517440-2 |oclc=54687539}}</ref>
