Licht (Light), subtitled "Die sieben Tage der Woche", is a cycle of seven operas composed by Karlheinz Stockhausen between 1977 and 2003. The composer described the work as an "eternal spiral" because "there is neither end nor beginning to the week." Licht consists of 29 hours of music.
The Helikopter-Streichquartett is one of Karlheinz Stockhausen's best-known pieces, and one of the most complex to perform. It involves a string quartet, four helicopters with pilots, as well as audio and video equipment and technicians. It was first performed and recorded in 1995. Although performable as a self-sufficient piece, it also forms the third scene of the opera Mittwoch aus Licht.
The Klavierstücke constitute a series of nineteen compositions by German composer Karlheinz Stockhausen.
Sirius: eight-channel electronic music and trumpet, soprano, bass clarinet, and bass is a music-theatre composition by Karlheinz Stockhausen, composed between 1975 and 1977. It is Nr. 43 in the composer's catalogue of works, and lasts 96 minutes in performance.
Klang —Die 24 Stunden des Tages is a cycle of compositions by Karlheinz Stockhausen, 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. The fourth composition is a theatre piece for a solo percussionist, and there are also two auxiliary compositions which are not part of the main cycle. The completed works bear the work (opus) numbers 81–101.
Montag aus Licht is an opera by Karlheinz Stockhausen in a greeting, three acts, and a farewell, and was the third of seven to be composed for the opera cycle Licht: die sieben Tage der Woche. The libretto was written by the composer.
In Freundschaft is a composition by Karlheinz Stockhausen, number 46 in his catalogue of works, which is playable on a wide variety of solo instruments.
Sonntag aus Licht is an opera by Karlheinz Stockhausen in five scenes and a farewell, to a libretto written and compiled by the composer. It is the last-composed of seven operas that comprise the cycle Licht (Light). Its stage premiere in 2011 was posthumous, more than three years after the composer's death.
Donnerstag aus Licht is an opera by Karlheinz Stockhausen in a greeting, three acts, and a farewell, and was the first of seven to be composed for the opera cycle Licht: die sieben Tage der Woche. It was written between 1977 and 1980, with a libretto by the composer.
Dienstag aus Licht is an opera by Karlheinz Stockhausen in a greeting and two acts, with a farewell, and was the fourth of seven to be completed for the opera cycle Licht: die sieben Tage der Woche. It was begun in 1977 and completed from 1988 to 1991, to a libretto by the composer.

Litanei 97 is a choral work by German composer Karlheinz Stockhausen, written in 1997. Although the words are taken from the text-composition cycle Aus den sieben Tagen and the conductor sings and plays elements from the Michael formula used in the composer's Licht cycle of operas, it is an independent work assigned the number 74 in Stockhausen's catalogue of works. It lasts about twenty minutes in performance.
