Klang (Stockhausen)
Encyclopedia
Klang—Die 24 Stunden des Tages (Sound—The 24 Hours of the Day) is a cycle of compositions by Karlheinz Stockhausen
Karlheinz Stockhausen
Karlheinz Stockhausen was a German composer, widely acknowledged by critics as one of the most important but also controversial composers of the 20th and early 21st centuries. Another critic calls him "one of the great visionaries of 20th-century music"...

, on which he worked from 2004 until his death in 2007. It was intended to consist of 24 chamber-music compositions, each representing one hour of the day, with a different colour systematically assigned to every hour. The cycle was not yet finished when the composer died, so that the last three "hours" are lacking. The 21 completed pieces include solos, duos, trios, a septet, and Stockhausen's last entirely electronic composition, Cosmic Pulses
Cosmic Pulses
Cosmic Pulses is the last electronic composition by Karlheinz Stockhausen, and it is number 93 in his catalog of works. Its duration is 32 minutes. The piece has been described as "a sonic roller coaster", "a Copernican asylum", and a "tornado watch"....

, and they bear the work (opus) numbers 81–101.

History and character

After having spent 27 years composing the opera-cycle Licht
Licht
Licht , subtitled "The Seven Days of the Week," is a cycle of seven operas composed by Karlheinz Stockhausen between 1977 and 2003. In total, the cycle contains over 29 hours of music.-Origin:...

 (1977–2004), Stockhausen felt he was shifting his focus from the visible world of the eyes—Licht is the German word meaning "light", as of the stars, the sun—to the invisible world of the ears. When planning his new cycle of pieces based on the hours of the day, he initially considered several possibilities for the title: Day, Nacht und Tag (Night and Day), Liebe (Love), Chi
Qi
In traditional Chinese culture, qì is an active principle forming part of any living thing. Qi is frequently translated as life energy, lifeforce, or energy flow. Qi is the central underlying principle in traditional Chinese medicine and martial arts...

 (the life energy), or Spiegel (Mirror). The name he finally settled on, Klang, means "sound", acoustic vibrations, but for Stockhausen, above all "the INNER EAR, for the divine Klang, the mystic sound of the beyond with the voice of the conscience, in German: die Stimme des Gewissens" (Stockhausen 2006a, 10).

Although the solo percussion work Himmels-Tür has a decidedly theatrical character, the cycle otherwise consists of essentially concert works (Günther 2008). Three are for unaccompanied solo performer, one is a duo, seven are trios, one a septet, one is a purely electronic composition, and the remaining eight compositions are for soloist accompanied by electronic music.

With Klang Stockhausen moved away from the formula technique
Formula composition

 (1970) until the completion of the opera-cycle Licht in 2004. The pieces are based on a 24-note series

, and from which other formal and parametric properties are derived on a work-by-work basis (Toop [2008a]). Starting from the Fifth Hour, this row is used in inversion, until returning to its original form from the Thirteenth Hour onward (Pasveer and Wesley 2008, 3–4).

Stockhausen also felt that he was returning to the moment form approach he had used in the late 1950s and 1960s, in works such as Kontakte

It seems that I am listening again more for moments, atmospheres, rather than formulas with their limbs, transpositions, transformations. Certainly both methods conjoint[ly] lead to good music. A special concentration and freedom must be trained for listening to the soul['s] vibrations. (Stockhausen 2006a, 10)


A new device of proliferating "rhythm families" was developed for the first "hour" (Himmelfahrt) and is employed in many of the subsequent pieces. In addition, the exploration of multiple simultaneous tempi, pioneered in Zeitmaße

, this is taken to the verge of sonic saturation (Toop [2008a]).

Initially, Stockhausen had no overall plan for the cycle but in the summer of 2006, as he was finishing Cosmic Pulses

Cosmic Pulses is the last electronic composition by Karlheinz Stockhausen, and it is number 93 in his catalog of works. Its duration is 32 minutes. The piece has been described as "a sonic roller coaster", "a Copernican asylum", and a "tornado watch"....

, he altered his method of work and grouped the component pieces into three subcycles. In doing so, he displaced Cosmic Pulses from its originally intended position as the Sixth to the Thirteenth Hour (Kohl 2009a, 13). One theory has been advanced that the Fibonacci series (1, 2, 3, 5, 8, 13, 21, etc.) may be the reason these two subcycles start on the fifth and thirteenth hours, and the second ends on the twenty-first (Pasveer and Wesley 2008, 3–4). Another hypothesis is that Stockhausen meant to close the circle with a third, seven-member, "overnight" subcycle covering hours 22, 23, 24, and the already-completed 1–4, which would drive home the fact that midnight is not a natural "beginning" of the daily cycle, but only an arbitrary, human convention. Combined with the "morning" (hours 5–12) and "afternoon-evening" (hours 13–21) subcycles, this would divide the 24 hours of Klang into a serial proportion pattern of 7:8:9 (Kohl 2009a, 14).

On 30 November 2007, Stockhausen wrote to Udo Zimmermann

, director of the Ars Viva Festival in Munich, politely declining an invitation to attend a performance on 25 January 2008, because "I have reserved the days—and nights—when your rehearsals and performance take place to work on a new composition." Doubtless the new work was to have been one of the remaining hours from Klang but, five days later, Stockhausen suddenly died, leaving the cycle incomplete (Frisius 2008, 165; Kohl 2009a, 14). After his death, a search in his sketchbooks failed to discover any plans for the remaining three hours (Pasveer and Bos 2010).

The last six component works to be premiered were given in Cologne

Accordingly I turn the circle by one step in order to coincide with a clock" (Stockhausen 2006a, 10).

In at least one case, the performer is cautioned to avoid "any associations with known cultures" (Stockhausen 2009c, II).

First Hour: Himmelfahrt

Himmelfahrt (Ascension), for organ or synthesizer, soprano, and tenor. 2004–05 (36 mins.). Work number 81. The specified colour is deep violet-blue (Stockhausen 2008a, cover; Stockhausen 2008b, cover).

Himmelfahrt was premiered at the Milan Cathedral on 5 May 2005 (version with organ), by Alessandro La Ciacera, organ, Barbara Zanichelli, soprano, Paolo Borgonovo, tenor, and Karlheinz Stockhausen, sound projection (Stockhausen 2006a, 3); the version with synthesizer was premiered in the Sülztalhalle, Kürten

The keyboardist's two hands are required to play in different tempos simultaneously, performing "temporal head-stands for both hands—actually impossible for us today—and the relationship of the tempo to the intensity of a sound-colour was composed by me in the spirit of the Ascension: unimaginable—unheard—invisible" (Stockhausen 2006a, 4). The composer felt this "is like compelling a man to the physical rupture that allows him to go in the form of a spirit to another world" (Gervasoni 2005a).

The text proclaimed by the two singers was written by Stockhausen himself, and refers freely to the Ascension of Christ. The vocal parts, however, only occur intermittently, and it is the keyboard instrument

 that accounts for the largest share of the music. The score describes an ascent, like climbing a stairway to the Most High, and is divided into 24 moments. The ascent, however, is not a constant progression—the climber sometimes seems to stop to look behind him or around him (Gervasoni 2008c, 67).

Second Hour: Freude

Freude (Joy), for two harps. 2005 (40 mins.). Work number 82. The specified colour is a medium blue (Stockhausen 2007e, cover; Stockhausen 2008b cover).

", to be sung in Latin by the two harpists as they play. Following the 24 verses of the Latin hymn, the work is composed, like the First Hour, in 24 moments, and the title was changed to Freude, because this was the fundamental feeling Stockhausen had about the composition (Stockhausen 2007a, 3).

The text setting is sometimes syllabic, sibilant, employs speech-song, and in places evokes plainchant and early polyphony. The music probes the meaning of joy through a deep and detailed text-setting reminiscent of the "frighteningly beautiful" Mikrophonie II

Fourth Hour: Himmels-Tür

Himmels-Tür (Heaven’s Door), for a percussionist and a little girl, 2005 (ca. 28 mins.). Work number 84. The specified colour is bright blue [Hellblau] (Stockhausen 2007f, cover; Stockhausen 2008b, cover).

—also had their origins in dreams.) Because of the indefinite pitches of the instruments (a large double-panelled door and an assortment of cymbals and gongs), Himmels-Tür is the only work in the Klang cycle that does not use the 24-note series extrapolated from the all-interval "Gruppen" row (Kohl 2008, 17; Toop 2008b, 199–200).

"A percussionist beats with wooden beaters on a heaven’s door made of wood. It is divided from bottom to top into six fields. Sometimes he (she) stomps on the floor with his (her) nailed shoes." There are fourteen main sections defined by moods, such as "cautious", "entreating", "agitated", and "angry", until finally, the door opens. "After a moment of silence, the percussionist cautiously steps through the doorway and disappears. A terrifying noise of tam-tams, hi-hats, and cymbals bursts out”, not to mention sirens. "A little girl comes out of the audience onto the stage, and disappears through the doorway. The metallic sounds become increasingly rare and gradually cease. Finally, the siren stops" (Stockhausen 2006b, 41).

, as well as in Himmelfahrt (Hour 1) and the twenty-second piece of Natural Durations (Hour 3) from Klang. The recorded sounds of strokes on the door are electronically processed to focus their pitch and extend their resonance, and a rin stroke of the corresponding pitch is added to each attack (Kohl 2008, 17).

The composition consists of a single, stately presentation of the 24-tone Klang row, in rhythms derived from the pitches. Within each of these long tones, Stockhausen's voice intones a different "noble word" (such as "hope", "fidelity", "balance", "generosity", etc.). The utter simplicity of this piece puts it at the opposite extreme from the hyper-complex Cosmic Pulses

, work on which was already in progress at the time Türin was created (Kohl 2008, 17).

There are two versions of Türin, one with the words spoken in German, the other in English. According to the composer, these "noble words" are meant to keep the Himmels-Tür open (booklet accompanying Stockhausen Complete Edition CD 86, pp. 12 & 24). This composition was not assigned a work-number by Stockhausen, but is now included in the official catalogue of his works as "Nr. 84 extra".

, with numerous adjustments to fit the range and character of the instruments, as well as a few small additions. While the bass clarinet and flute versions are purely instrumental, in the trumpet version the player speaks three words between the four introductory notes: "Lob sei Gott" ("May God be praised").

"Harmonies come into being from successions of melodic groups.… At the end of a group, its pitches are repeated as very fast periods without rhythm and in different registral distribution, so that the melody has a harmonic effect, like a vibrating chord" (Stockhausen 2007c, 33 & 36).

Stockhausen’s original idea for the Fifth Hour of Klang was to have an unaccompanied instrumental piece in three different versions (for bass clarinet, flute, and trumpet), followed by a longer trio for the same instruments, built from the same material. In this conception, it was to have been called Akkorde (Chords). The title was later changed to Harmonien. Late in 2006 or early in 2007, when Stockhausen decided to group some of the hours into subcycles, the original trio became Hour 6, and the first of a set of seven trios extending to Hour 12, all based on the material of the three versions of Harmonien (Kohl 2009c, 22). Except for Glanz, the titles of these trios are amongst the "noble words" found in Türin, which are meant to "hold open the Heaven's Door" of the fourth hour (Stockhausen-Stiftung für Musik 2010, 28, 30, 56 & 58).

Katikati

At about the time he was working on Harmonien in 2006, Stockhausen composed a short (ca. 4 minutes) flute piece for Kathinka Pasveer, titled Katikati. This work has not yet been premiered, and its connection (if any) with the Klang cycle has not been determined, but it has been assigned the work number 85.2 extra, following the flute version of Harmonien in the composer's work list (Stockhausen-Verlag 2010, 49).

Sixth Hour: Schönheit

Schönheit (Beauty), for flute, bass clarinet, and trumpet, 2006 (ca. 30 mins.). Work number 86. The specified colour is HKS 51 (turquoise blue).

The premiere of Schönheit was given in Lisbon on 5 October 2009, at the Grande Auditório of the Gulbenkian Foundation by Suzanne Stephens (bass clarinet), Marco Blaauw (trumpet) and Kathinka Pasveer (flute). Schönheit was commissioned by the music department of the Fundaçaõ Calouste Gulbenkian

s. This permutability is an example of what Stockhausen called "polyvalent form" (Kohl 2009c). According to Marco Blaauw, "Like Bach’s Art of the Fugue, it is therefore a work of synthesis which requires a great intellectual effort on the part of the listener" (quoted in Martin 2009). As in the trumpet version of Harmonien, the performers punctuate the introductory chords with the words "Lob sei Gott", spoken in unison.

Seventh Hour: Balance

Balance, for flute, cor anglais, and bass clarinet. 2007 (ca. 30 mins.). Work number 87. The specified colour is HKS 54 (bluish green [Verkehrsgrün]) (Stockhausen 2008b, cover).

 management to add four more instruments to the ensemble (Beer 2008; Swed 2008). The original trio remains as the main structure, but four inserts interrupt as "magic moments", in which other instruments engage in dialogue with the trio: the first is an imperious solo oboe, the second a stentorian trumpet-trombone duo, and the last a somnolent tuba. The third insert, on the other hand, is self-reflective, performed by the core trio and including, like the Seventh Hour, the spoken Latin words "Gloria in excelsis Deo et in terra pax in hominibus bonae voluntatis" (Kohl 2008, 16).

In the score, Stockhausen specified that the work should be performed with a "light sculpture" in the middle of the stage, and this sculpture should gradually become more brilliant. For the world premiere in Amsterdam, a pyramidal sculpture was designed by the lighting technician Maarten Warmerdam, which was made to increase in brightness over the course of the performance (Stockhausen 2011, I, III). One critic has described it as "a cheesy 4-foot pyramid" (Swed 2008).

Eleventh Hour: Treue

Treue (Fidelity), for E clarinet, basset horn, and bass clarinet. 2007 (ca. 30 mins.). Work number 91. The specified colour is HKS 2 (zinc yellow [Zinkgelb]) (Stockhausen 2008b, cover; Stockhausen 2010d, I–II).

 on 7 May 2007 at Auditorium Parco della Musica, Sala Sinopoli (Stockhausen 2007a).

The music is made from 24 melodic loops, each with a different number of pitches (from 1 to 24) and in a different tempo, calculated in sequences of eight pulses lasting between 1.17 and 240 per minute. This means the slowest tempo is 1.17 x 8 = 9.36 pulses per minute, and the fastest is 240 x 8 = 1920 pulses per minute. These loops, with a total pitch span of about seven octaves, were created and synchronized by Antonio Pérez Abellán. The loops enter successively from low to high and from slow to fast, and make their exits in the same order. Kathinka Pasveer "enlivened" the rhythms and pitches by hand, according to the composer's instructions, causing accelerandos and ritardandos around each basic tempo, and glissandos upwards and downwards around the melodic pitch successions (Stockhausen 2007b, 22 & 40). The music therefore begins and ends with relatively clear polyphony of the loops, but in the central part this dissolves into a statistical mass of sound in which only general shifts of texture and colour can be perceived (Grant 2008, 19).

In addition to all this, with the collaboration of Joachim Haas and Gregorio Karman of the Experimental Studio for Acoustic Art in Freiburg, Stockhausen spatialized each of the 24 layers in eight-channel sound, with a total of 241 different trajectories in space "as if I had to compose the orbits of 24 moons or 24 planets. … If it is possible to hear everything I do not yet know—it depends on how often one can experience an 8-channel performance. In any case, the experiment is extremely fascinating" (Stockhausen 2007b, 22 & 40).

The following eight pieces in the cycle each use three of the twenty-four melodic layers from Cosmic Pulses as the accompaniment for a slower-moving solo part. Four of these solos are vocal (hours 14, 15, 18, and 19), and four are for wind instruments (hours 16, 17, 20, and 21).

Fourteenth Hour: Havona

Havona, for bass and electronic music (layers 24, 23, 22 from Cosmic Pulses) 2007 (25 mins., 10 secs.). Work number 94. The specified colour is HKS 5 (melon yellow) (Stockhausen 2008b, cover; Stockhausen 2009c, cover and II).

, and all are named in the text of Havona, as stages in a journey with the goal of studying cosmic music in Paradise. However, this text, like those for the following Hours, is not taken directly from the Urantia Book, but was written by the composer.

In the Urantia Book, Havona is "the central universe, … an existential, perfect, and replete universe surrounding the home of the eternal Deities, the center of all things" (Urantia Foundation 1955, 360).
This central planetary family … is far-distant from the local universe of Nebadon. It is of enormous dimensions and almost unbelievable mass and consists of one billion spheres of unimagined beauty and superb grandeur … arranged in seven concentric circuits immediately surrounding the three circuits of Paradise satellites. There are upwards of thirty-five million worlds in the innermost Havona circuit and over two hundred and forty-five million in the outermost, with proportionate numbers intervening. (Urantia Foundation 1955, 152)


According to the Urantia Book, "Harmony is the speech of Havona", and music is the eternal, universal language of men, angels, and spirits (Urantia Foundation 1955, 500).

Fifteenth Hour: Orvonton

Orvonton, for baritone and electronic music (layers 21, 20, 19 from Cosmic Pulses) 2007 (24 mins.). Work number 95. The specified colour is HKS 6 (yellow-orange) (Stockhausen 2010f, cover, I, and III).

 by Jonathan de la Paz Zaens, with sound direction by Hannah Weirich, as part of the MusikTriennale Köln (Gimpel 2010).

According to the Urantia Book, "outside Havona there are just seven inhabited universes, the seven superuniverses", and the Earth's (Urantia) "local universe of Nebadon belongs to Orvonton, the seventh superuniverse" (Urantia Foundation 1955, 164–65).

In September 2007, when composition of Hours 14 to 21 was substantially completed, Stockhausen explained in an interview: "in the new works which I am now composing in Klang, I very often describe, in the sung text, how the piece that you are hearing is composed—and in fact right down to the details: how the rhythm goes, how the melody goes, how the harmony goes. So I very much love the fact that the music explains itself" (Stockhausen and Ermen 2007). Stockhausen composed Orvonton with de la Paz Zaens' voice in mind, and the composer assigned to him its extraordinarily long text (56 lines) because of the clarity of his German diction (Tariman 2011). The text provides "an analysis of the material and structure of the piece itself, and is also meant humorously" (Nonnenmann 2010): "Orvonton: I am a baritone, … / Layer nineteen has twenty-three tones as sound loop. / In the basic tempo 3.75 each note lasts 2 seconds, / and therefore the loop lasts 23 x 2 = 46 seconds", and so on (Nonnenmann 2010). Later on, this text includes an artistic credo: Each sound is a universe. / But one cannot tell if it is beautiful by the numbers: / that depends on who is counting. / Four hundred and forty Hertz is neither beautiful nor ugly. / Beauty lives. / … / Art music is not honky-tonk [i.e., low music-hall entertainment], / its number games need moments every now and then for the soul, / that touch, astonish: / time stands still".

Sixteenth Hour: Uversa

Uversa, for basset horn and electronic music (layers 18, 17, 16 from Cosmic Pulses) 2007 (22 mins., 40 secs.). Work number 96. The specified colour is HKS 7, orange (Stockhausen 2010g, II).

Uversa is the headquarters of the superuniverse of Orvonton (Urantia Foundation 1955, 74).

The sections of this and the other instrumental solos with electronic music are articulated by lines of spoken text in German, written by Stockhausen and loosely based on the Urantia Book. These were spoken by Kathinka Pasveer, recorded, and mixed with the electronic music on the eight-channel tape. The concluding portion refers to the learning of art by pilgrims to Uversa (Stockhausen-Stiftung für Musik 2010, 47; Stockhausen 2010g, I):

, as part of the MusikTriennale Köln (Gimpel 2010; Stockhausen 2010h, I).

Nebadon is the local universe to which the earth (Urantia) belongs (Urantia Foundation 1955, 165).

Each of Nebadons 24 sections is announced by a word or phrase written into the score by Stockhausen. These mostly isolated words, in a mixture of English and German, begin to form a connected narrative in the last seven lines (original in German):
ten million inhabited worlds
in the superuniverse
ORVONTON
and central universe
HAVONA
rotates around SAGITTARIUS
holy NEBADON

This text was recorded and mixed into the electronic music by Kathinka Pasveer. The horn is amplified and projected during a performance over all eight loudspeaker groups, which surround the audience in a circle. The solo part is notated flexibly, in order to allow the performer great freedom in forming groups, notes, and figures (Stockhausen 2010h, I and IV).

Eighteenth Hour: Jerusem

Jerusem, for tenor and electronic music (layers 12, 11, 10 from Cosmic Pulses) 2007 (20 mins., 40 secs.) Work number 98. The specified colour is HKS 22 (orange-red) (Stockhausen 2010i, cover, I, and III).

Jerusem is a planet, the headquarters of the cluster of 57 major and minor satellites constituting the administrative centre of the local system called Satania, which forms part of the local universe Nebadon (Urantia Foundation 1955, 509, 519, 1250). "Music, such as Urantia mortals understand, attains its highest expression in the schools of Jerusem" (Urantia Foundation 1955, 500).

The Urantia Books description is reflected in the very short text for Jerusem (the words are repeated frequently), written by the composer (Stockhausen 2010i, III):

Universes

Nineteenth Hour: Urantia

Urantia, for soprano (live or prerecorded) and electronic music (layers 9, 8, 7 from Cosmic Pulses) 2007 (19 mins., 40 secs.). Work number 99. The specified colour is HKS 23 (fire-engine red [Verkehrsrot]) (Stockhausen 2008e, cover, I, and II).

Urantia was premiered in the Queen Elizabeth Hall

 at the Southbank Centre, London, on 8 November 2008, by Kathinka Pasveer, soprano (prerecorded) and sound projection (Kohl 2008, 21).

Urantia is the name given to our earth in the Urantia Book (Urantia Foundation 1955, 1), "commonly referred to as 606 of Satania in Norlatiadek of Nebadon, meaning the six hundred sixth inhabited world in the local system of Satania, situated in the constellation of Norlatiadek, one of the one hundred constellations of the local universe of Nebadon" (Urantia Foundation 1955, 485).

The three layers of electronic music—which rotates in different orbits around the hall, projected in eight channels—are moderately high in pitch and contain amongst the highest number of notes of all of the layers from Cosmic Pulses: 20, 21 and 22 notes. The solo part, by contrast, is one of the simplest of this section of Klang. The German text, written by the composer, has only 26 syllables, and introduces just one new syllable in each of the work's 26 sections (Kohl 2008, 21):
Rotations everywhere

URANTIA in the cosmos

Father, Son and Holy Ghost

-History:The first historic name for the city was, according to Claudius Ptolemy's reports, Treva.But the city takes its modern name, Hamburg, from the first permanent building on the site, a castle whose construction was ordered by the Emperor Charlemagne in AD 808...

 on 6 August 2008 by Marcus Weiss, saxophone (Krause 2008; Stephan 2008; Mischke 2008).

Edentia is described in the Urantia Book as a planet, the centremost and largest of a cluster of 771 "architectural spheres" in the constellation of Norlatiadek, within the local universe of Nebadon (Urantia Foundation 1955, 485). "There is harmony of music and euphony of expression in the orations of Salvington and Edentia which are inspiring beyond description" (Urantia Foundation 1955, 503–04).

The saxophonist, who must play from memory, is amplified using a transmitter
Transmitter
In electronics and telecommunications a transmitter or radio transmitter is an electronic device which, with the aid of an antenna, produces radio waves. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating...

 and receiver
Receiver (radio)
A radio receiver converts signals from a radio antenna to a usable form. It uses electronic filters to separate a wanted radio frequency signal from all other signals, the electronic amplifier increases the level suitable for further processing, and finally recovers the desired information through...

, and in some sections uses a reverberation unit with both long and extremely long reverberation times. The 24 sections of Edentia are articulated with texts written by the composer. These texts, recorded and mixed into the electronic music, at first describe the Edentia of the Urantia Book, and then announce the musical devices being used in the later sections: "trills", "repetitions", "tremoli", "micro-intervals", etc. (Stockhausen 2009d, I–II).

Twenty-first Hour: Paradies

Paradies (Paradise), for flute and electronic music (layers 3, 2, 1 from Cosmic Pulses) 2007 (18 mins., 02 secs.). Work number 101. The specified colour is HKS 31 (purple) (Stockhausen 2009e, cover and II).

Paradies was premiered by Kathinka Pasveer, flute, and Bryan Wolf, sound direction, at the Schleswig-Holstein Musik Festival
Schleswig-Holstein Musik Festival
The Schleswig-Holstein Musik Festival is a classical music festival held every year in summer time all over the state of Schleswig-Holstein in Northern Germany....

, at the Laeiszhalle
Laeiszhalle
The Laeiszhalle is a concert hall in Hamburg, Germany and home to the Hamburger Symphoniker.The hall is named after the German shipowning company F. Laeisz, founder of the concert venue and was planned by the architect Martin Haller.-External links:...

 in Hamburg on 24 August 2009 (Stockhausen-Stiftung für Musik. 2009, 9). Paradies was commissioned by the North German Radio (NDR), Hamburg (Stockhausen-Stiftung für Musik. 2010, 10 & 38).

According to the Urantia Book, "Paradise is the gigantic nuclear Isle of absolute stability which rests motionless at the very heart of the magnificent eternal universe" (Urantia Foundation 1955, 152).

As with the preceding pieces, Paradies has a text describing itself. In this case, it is spoken by Kathinka Pasveer on the tape, mixed with the electronic music. The 25 short lines articulate the 24 musical sections of the work. As in Orvonton, after announcing the piece in the first seven lines, the German words from section 8 onward analyse the stages of the work itself: "24 lines of notes for the flute /
from 1 to 24 pitches / of the original row / source of all melodies / each line, a different low note / fragments of the groups / jumps in the entire space / fitting dynamics / articulation free / legato or staccato / pauses ad libitum / flexible tempo / one insert per line / for the fantasy / and the play / and the joy / for the magic / the eternal GOD" (Stockhausen 2009e, I).
