Harlekin (Harlequin) is a composition for unaccompanied clarinet by Karlheinz Stockhausen, named for the commedia dell'arte character Harlequin. It was composed in 1975 and is Number 42 in his catalogue of works. A shorter, derived work called Der kleine Harlekin is Number 42½.
Harlekin was composed for the clarinetist Suzanne Stephens to dance to her own playing. It was begun at Easter 1975 in Morocco, and completed on Christmas Eve of the same year on Big Corn Island off the coast of Nicaragua.In an interview from October 1984, Stockhausen recalled the circumstances: "I can see it in front of me. A rocky shore with a small restaurant on it, and the timber house where I wrote most of HARLEKIN. I can see the oil that was poured on the floor to fight those horrid cockroaches". The work was premiered on 7 March 1976 in the Große Sendesaal of the WDR in Cologne by Suzanne Stephens. Although intended primarily for a dancing clarinetist, it can also be performed as "pure" music, in which case the notated dance rhythms are to be played on tabla, a Kandy drum, or similar drum. It may also be performed by a clarinetist at the side of the stage on which a dancer performs the choreography. There is an arrangement for flute, as well.
Harlekin is composed using formula technique and falls into seven sections, which are played without a break:
Part 6 is subdivided into two parts, titled "Dialog mit einem Fuß" (Dialog with a Foot) and "Harlekins Tanz" (Harlequin's Dance).
The whole work is composed as a single large wave.The work is based on a melodic formula first exposed in its full form in section 3, "Der verliebte Lyriker". Up to this point, the melody is gradually evolved, and from here onward it is composed out in a variety of ways. The cyclic compositional processes are associated with rotating movements by the performer, which recall the rotating movements of electronic sounds in Kontakte , and the improvised motions produced by use of the "sound mill" in the spherical auditorium of the German Pavilion at Expo '70 in Osaka. The duration is 45 min.
"Harlequin's Dance", the second subsection of part 6, became an independent piece with the title Der kleine Harlekin, and was given the work-number 42½. This piece was premiered by Suzanne Stephens on 3 August 1977 at the Centre Sirius in Aix-en-Provence. Like the parent composition, Der kleine Harlekin is meant for a dancing clarinetist, but can be performed as a duo by a clarinetist and a dancer, or a clarinetist and a drummer. It also has been arranged for flute.
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.
Formula composition is a serially derived technique encountered principally in the music of Karlheinz Stockhausen, involving the projection, expansion, and Ausmultiplikation of either a single melody-formula, or a two- or three-voice contrapuntal construction.
Ausmultiplikation is a German term used by the composer Karlheinz Stockhausen to describe a technique in which a long note is replaced by shorter "melodic configurations, internally animated around central tones", resembling the ornamental technique of divisions in Renaissance music. Stockhausen first described this technique in connection with his "opus 1", Kontra-Punkte, composed in 1952–53, but in his later formula composition there is a related method of substituting a complete or partial formula for a single very long tone in a much slower, "more background" projection of the formula. When this is done at more than one level, the result is reminiscent of a fractal.
Collegium Vocale Köln is a German vocal ensemble, founded in 1966 as a quintet when its members were still students at the Rheinische Musikschule in Cologne. It is directed by Wolfgang Fromme, who also sings tenor in the ensemble. They are best known as the group for which Karlheinz Stockhausen composed Stimmung in 1968, a work which they had performed more than three hundred of times throughout the world by 1986. The original impetus for the ensemble's founding, however, was an appearance by Alfred Deller at the Cologne Courses for Early Music, and the group has always performed both early and contemporary works.
Kontakte ("Contacts") is an electronic music work by Karlheinz Stockhausen, realized in 1958–60 at the Westdeutscher Rundfunk (WDR) electronic-music studio in Cologne with the assistance of Gottfried Michael Koenig.

Zeitmaße is a chamber-music work for five woodwinds composed in 1955–1956 by German composer Karlheinz Stockhausen; it is Number 5 in the composer's catalog.

Its title refers to the different ways that musical time is treated in the composition.
