Des Knaben Wunderhorn (Mahler)

The songs of Des Knaben Wunderhorn (The Boy’s Magic Horn) by Gustav Mahler are voice-and-piano and voice-and-orchestra settings of German folk poems chosen from a collection of the same name assembled by Achim von Arnim and Clemens Brentano and published by them, in heavily redacted form, between 1805 and 1808.
Ten songs set for soprano or baritone and orchestra were first published by Mahler as a cycle in 1905, but in total 12 orchestral songs exist, and a similar number of songs for voice and piano.
History of composition.
Mahler's self-composed text for the first of his "Lieder eines fahrenden Gesellen" ('Songs of a Travelling Journeyman', regularly translated as 'Songs of a Wayfarer'; 1884–1885) is clearly based on the "Wunderhorn" poem 'Wenn mein Schatz'; his first genuine settings of "Wunderhorn" texts, however, are found in the "Lieder und Gesänge" ('Songs and Airs'), published in 1892 and later renamed by the publisher as "Lieder und Gesänge aus der Jugendzeit" ('Songs and Airs from Days of Youth'). The nine "Wunderhorn" settings therein were composed between 1887 and 1890, and occupied the second and third volumes of this three-volume collection of songs for voice and piano. The titles of these nine songs (different in many cases from the titles of the original poems) are as follows:

Mahler began work on his next group of "Wunderhorn" settings in 1892. A collection of 12 of these was published in 1899, under the title "Humoresken" ('Humoresques'), and formed the basis of what is now known simply (and somewhat confusingly) as Mahler's 'Songs from "Des Knaben Wunderhorn"'. Whereas the songs in the "Lieder und Gesänge" collection were conceived for voice and piano, with no orchestral versions being produced by the composer, the "Humoresken" were conceived from the beginning as being for voice and orchestra, even though Mahler's first step was the production of playable and publishable voice-and-piano versions. The titles in this 1899 collection are:
'Urlicht' (composed ?1892, orch. July 1893) was rapidly incorporated (with expanded orchestration) into the 2nd Symphony (1888–1894) as the work's fourth movement; 'Es sungen drei Engel', by contrast, was specifically composed as part of the 3rd Symphony (1893–1896): requiring a boys' chorus and a women's chorus in addition to an alto soloist, it is the only song among the twelve for which Mahler did not produce a voice-and-orchestra version and the only one which he did not first publish separately. Other songs found themselves serving symphonic ends in other ways: a voiceless version of "Des Antonius von Padua Fischpredigt" forms the basis of the Scherzo in the 2nd Symphony, and "Ablösung im Sommer" is adopted in the same way by the 3rd. 
An additional setting from this period was "Das himmlische Leben" ('The Heavenly Life'), of February 1892 (orch. March 1892). By the year of the collection's publication (1899) this song had been re-orchestrated and earmarked as the finale of the 4th Symphony (1899–1900), and thus was not published as part of the "Des Knaben Wunderhorn" collection, nor was it made available in a voice-and-piano version.
After 1901, 'Urlicht' and 'Es sungen drei Engel' were removed from the collection, and replaced in later editions by two other songs, thus restoring the total number of songs in the set to twelve. The two new songs were:
Shortly after Mahler's death, the publisher (Universal Edition) replaced Mahler's own piano versions of the "Wunderhorn" songs by piano reductions of the orchestral versions, thus obscuring the differences in Mahler's writing for the two media. In spite of this, voice-and-piano performances, especially of the 'lighter' songs, are frequent. The original piano versions were re-published in 1993 as part of the "critical edition", edited by and Thomas Hampson.
Arrangement for chamber ensemble.
In 2012, Ensemble Mini commissioned (as part of its "mini-Mahler series") composer/arranger Klaus Simon to transcribe the songs for a chamber ensemble of 16 musicians, the premiere of which was performed at Berliner Philharmonie on 20 June 2012. It is also published by Universal Edition.
Other composers.
Poems from the same collection have also been set as "Lieder" by several composers, including Mendelssohn, Schumann, Loewe, Brahms, Schoenberg, Webern, and Zemlinsky.
