The last element to be completed was the Sonntags-Anschied (Sunday Farewell), which was adapted for five synthesizers in 2003 from Hoch-Zeiten für Chor. It was premiered on 1 August 2004 in the Sülztalhalle in Kürten as the second concert of the 2004 Stockhausen Courses. The performers were Frank Gutschmidt, Benjamin Kobler, Marc Maes, Antonio Pérez Abellán, and Fabrizio Rosso. In concert performances such as the premiere it may be performed live, but in the context of the opera it is intended to be heard in the foyer and/or outside the hall in five-channel playback, possibly with visual projections (Toop 2005, 1–2). There are also two further versions of this Abschied, one for solo percussionist and ten-channel tape titled Strahlen (Rays), the other as Klavierstück XIX, for synthesizer and five-channel tape. Work on the ten-channel electronic music for Strahlen was begun in 2003 by the ZKM, Karlsruhe, but was interrupted in 2004 in favour of producing the visual elements for Licht-Bilder. The tape part was not finished until 2010, though a preliminary version was used for the world premiere on 4 December 2009 in Karlsruhe, with László Hudacsek, vibraphone.

Synopsis

Sonntag takes as its subject our solar system
Solar System
The Solar System consists of the Sun and the astronomical objects gravitationally bound in orbit around it, all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago. The vast majority of the system's mass is in the Sun...

 and the relationships of all the planets that orbit the sun (Stockhausen 1989, 200). In this opera, the earth and life on it is represented as the result of the union of light and water. These two elements are presented in the first scene, and the rest of the opera celebrates the evolution of life, of plants, animals, humans, and above all this the planets, moons, and heavenly constellations (Stockhausen 2011, 111, 191). There are five scenes, and a concluding "farewell".

Scene 1: Lichter—Wasser (Sunday Greeting)

Lichter—Wasser (Lights—Waters) is both the first scene and the "Gruß" (greeting) of the opera. An initial duet by the soprano (Eve) and tenor (Michael) is followed by the entrance of the orchestra, who take their places throughout the audience, which is arranged in triangular segments facing the centre. Each musician is provided with a rack with a lamp and a glass of water. Seventeen high-register instruments are identified by seventeen blue lamps, corresponding to the Michael formula, and twelve lower-register instruments are lit by green lamps, corresponding to the Eve formula. The music rotates through the space in two simultaneous layers and in 12 successive waves. These rotations are related to the planets and moons of our solar system, whose names, astronomical characteristics, and symbolisms form a part of the sung texts, which were written by the composer. At the end, the musicians make their exit and the soprano and tenor sing a closing duet (Stockhausen 2011, 15–17, 135–37).

Scene 2: Engel-Prozessionen

In the second scene, Engel-Prozessionen (Angel Processions), seven groups of angels move through the space singing God’s praises in seven languages (Ulrich 2011, 3). The seventh group consists of four soloists, and are the Angels of Joy (Sunday Angels). They sing in German. The soprano and tenor soloists should either be the same as in scene 1, or strongly resemble them. The other six choirs are Angels of Water (Monday Angels), Angels of Earth (Tuesday Angels), Angels of Life (Wednesday Angels), Angels of Music (Thursday Angels), Angels of Light (Friday Angels), and Angels of Heaven (Saturday Angels), and sing in Hindi, Chinese, Spanish, English, Arabic, and Swahili, respectively. The texts were all written by the composer in German, and translated into the respective languages (Stockhausen 2011, 25, 30, 145–47).

Scene 3: Licht-Bilder

The scene Licht-Bilder is performed by two pairs of musicians, a flute and basset horn on the one hand, and a tenor and trumpet on the other. The tenor (Michael) sings the praises of God in the form of His creations, manifested from stones to spirits. The music is accompanied by corresponding light images, hence the title of the scene (Ulrich 2011, 3). The flute and basset horn represent Eve, while the tenor and trumpet represent Michael, and each pair always sound together. Although the musical material is all drawn from the Michael and Eve layers of the Licht superformula, the assignment of these melodies to the pairs changes from section to section (Ulrich 2011, 38). The musical figures given to the basset horn and flute on the one hand, and to the tenor and trumpet on the other, are gradually displaced and then brought together again seven times, forming large phases corresponding to the days of the week. At the same time, movements of the performers on the stage corresponding to the musical figures are composed, and the waves are mirrored by a double ring modulation

, creating new harmonies and timbres (Stockhausen 2011, 33–34, 151–52)

Scene 4: Düfte-Zeichen

The fourth scene recapitulates the seven days of the entire Licht cycle. The protagonists explain each day in terms of their characteristic signs and scents. Afterward, Eve appears as Earth Mother

 (sung by an alto), and Michael appears in the form of a boy soprano (Ulrich 2011, 3). The seven fragrances chosen for the days of the week, their associated geographical areas, and the seven voices and voice combinations are (Stockhausen 2006, V, VII, XXI, XXIII):
  1. Monday: Cúchulainn (Ireland), solo for high soprano
  2. Tuesday: Kyphi

     (Africa), duet for high soprano and high tenor

An alto voice from outside the hall, identifying hersalf as Eve, causes the soloists to run out, in turbulence. They return in procession, escorting the alto to the front while singing an "overtone chant". The alto Eve calls the boy Michael to her out of the audience, they sing a mystical duet, and she takes him with her into another world (Stockhausen 2006, V, XVIII, XXI, XXX).

Scene 5: Hoch-Zeiten for Choir and for Orchestra

Hoch-Zeiten (High Times, or Marriages) is performed simultaneously in two different halls by five choral groups and five orchestral sections, respectively. The performance is then repeated, with the audiences changing halls (Ulrich 2011, 4). As such, these two versions are sometimes regarded as both the fifth and sixth scenes of Sonntag (Stockhausen 2003a, 5). The basic structure of the orchestral version is identical to that of Hoch-Zeiten for Choir, but has added to it five duos and two trios performed by the first-desk players of the orchestra. These ensembles are recollections of characteristic moments from each of the seven operas in the Licht cycle, presented not in weekday order but in the order they were composed (Stockhausen 2004b, 5, 7–28):
  1. Thursday duo, for trumpet and clarinet, quoting from Mondeva, act 1, scene 2 of Donnerstag
  2. Saturday duo, for flute and trombone, quoting from Kathinkas Gesang, scene 2 of Samstag
  3. Monday duo, for viola and cello, quoting from Wochenkreis, the second "situation" of act 2, scene 3 (Evas Lied) of Montag
  4. Tuesday duo, for flugelhorn and trombone, quoting from Pietà, in act 2 of Dienstag
  5. Friday duo, for oboe and bassoon, quoting from Elufa, the ninth "real scene" of Freitag
  6. Wednesday trio, for clarinet, violin, and cello, quoting from the "Carousel" section of Michaelion, scene 4 of Mittwoch
  7. Finally, a Sunday trio for flute, viola, and synthesizer, quoting the opening of Lichter—Wasser, the first scene of Sonntag.

Sonntags-Abschied

The Sunday Farewell is essentially Hoch-Zeiten for choir played by five synthesizers, including the phonetic notation of the original vocal texts. It is not so much an arrangement as an adaptation, and is intended for five-channel playback in recorded form in the foyer and outdoors as the audience exits the theatre (Toop 2005, 2).
