Stimmung, for six vocalists and six microphones, is a piece by Karlheinz Stockhausen, written in 1968 and commissioned by the City of Cologne for the Collegium Vocale Köln. Its average length is seventy-four minutes, and it bears the work number 24 in the composer's catalog. It is at the same time a serial and a tonal composition (Toop 2005, 39; Stuppner 1974).
The German word "Stimmung" has several meanings, including "tuning" and "mood". The word is the noun formed from the verb "stimmen", which means "to harmonize, to be correct", and related to "Stimme" (voice). The primary sense of the title "implies not only the outward tuning of voices or instruments, but also the inward tuning of one's soul" (Hillier 2007, 4). According to the composer, the word
means "tuning," but it really should be translated with many other words because Stimmung incorporates the meanings of the tuning of a piano, the tuning of the voice, the tuning of a group of people, the tuning of the soul. This is all in the German word. Also, when you say: We're in a good Stimmung, you mean a good psychological tuning, being well tuned together. (Cott 1973, 162)
Stimmung is in just intonation. Six singers amplified by six microphones tune to a low B♭1 drone, inaudible to the audience, and expand upwards through overtone singing, with that low B♭'s harmonics 2, 3, 4, 5, 7, and 9 (B♭2, F+2, B♭3, D4, A♭+4, and C+5) becoming in turn fundamentals for overtone singing. It is composed using what the composer calls moment form, and consists of 51 sections (called "moments"). It is "the first major Western composition to be based entirely on the production of vocal harmonics" (Gregory Rose and Ireland 1986)[not in citation given] or, alternatively, the first "to use overtones as a primary element" (Rose and Emmerson 1979, 20). An additional innovation is "the unique kind of rhythmic polyphony which arises from the gradual transformation/assimilation of rhythmic models" (Toop 2005, 48).
The harmonies of Stimmung are composed from 108 pitches: twelve different tones for each of the three women's voices, and twenty-four for each of the three men. Not only do the performers produce partials from the overtone series in each note they sing, but all of the fundamental tones are also related by whole-number overtone ratios. In this way, overtones are composed upon overtones, generating a range of degrees of harmonic fusion (Stockhausen 2009, 206).
According to the 1986 Hyperion Singcircle liner notes:
- In each section a new overtone melody or 'model' is introduced and repeated several times. Each female voice leads a new section eight times, and each male voice, nine times. Some of the other singers gradually have to transform their own material until they have come into 'identity' with the lead singer of the section . . . by adopting the same . . . tempo, rhythm and dynamics. When the lead singer feels that 'identity' has been reached, he or she makes a gesture to another singer who leads the next section. Each model is a set of rhythmic phonetic patterns, often with actual words used as their basis, such as 'Hallelujah' or 'Saturday'.
- In 29 of the sections, 'magic names' are called out. These are the names of gods and goddesses from many cultures—Aztec, aboriginal and Ancient Greek, for instance—and have to be incorporated into the character of the model. The erotic and intimate love-poems that are recited were written by Stockhausen 'during amorous days' in 1967. (Rose and Ireland 1986)
The order of the rhythmic models and the distribution of the poems and "magic names" are decided by the performers, but the sequence of pitches in the 51 moments is fixed (Stuppner 1974; Rose and Emmerson 1979; Rigoni 1992). Though the 1968 "Paris version" used by the Collegium Vocale Köln at the world première has been published (as No. 24½ in Stockhausen's catalog), the 1977 "Singcircle version" (directed by Gregory Rose) has been well documented in Rose and Emmerson 1979, and both versions have been performed throughout the world. Singcircle performances include the Round House on 21 November 1977, a 1977 BBC Promenade Concert at the Royal Albert Hall, in Liverpool's Anglican Cathedral as part of the 1980 Hope Street Festival (Rose and Ireland 1986), and at the Barbican in 1985, with the composer at the mixing desk (Dear and Davalle. 1985). Singcircle's performance at the 2005 City of London Festival was recorded and broadcast on BBC Radio 3's Hear and Now on 20 August 2005. In 2003, Paul Hillier made a "Copenhagen version" for the Theatre of Voices, which he directs. This version, too, has been performed on tour, and a recording has been released on CD. Other groups that have performed Stimmung include the London Sinfonietta Voices, Ensemble Belcanto, Neue Vocalsolisten Stuttgart, the Aquarius Consort, and the Dunedin Consort, according to the performance database of Universal Edition.
Influences and reception 
Stockhausen himself attributes a month spent walking among ruins in Mexico as his primary influence, Stimmung recreating that 'magic' space. On the other hand, he also describes the snow on frozen Long Island Sound in February and March 1968 (when he was composing Stimmung in Madison, Connecticut), as "the only landscape I really saw during the composition of the piece" (Cott 1974, 163). In a letter to Gregory Rose written on 24 July 1982 (printed in the liner notes to Hyperion CDA66115), he describes how, in the small house his wife Mary had rented it was only possible for him to work at night because their two small children needed quiet during the day. He could not sing aloud, as he had done initially, but began to hum quietly, listening to the overtone melodies. Mary reports that Stockhausen first discovered the technique when listening to their small son Simon producing multiple tones while humming in his crib after falling asleep. In this way, Stockhausen became "the first Western composer to use this technique of singing again—in the Middle Ages it had been practiced by women and children in churches, but was later entirely supplanted by masculine Gregorian music" (Bauermeister 2011, 217–18).
[Young's] influence on already established composers who were themselves his student mentors is not, however, confined to Cage. Karlheinz Stockhausen's exploration of the harmonic series, notably in Stimmung (1968), has often been linked to Young's example. [...] The German composer seems to have visited Young and Zazeela when in New York, in 1964 or 1965, and listened to a rehearsal of The Theatre of Eternal Music. He requested tapes of the group's performances which, perhaps surprisingly, Young gave him. Stockhausen's own musicians visited Young and Zazeela's Dream House installation in Antwerp in 1969. (Potter 2002, 89)
I didn't hear any of Feldman's music until 1962, when I heard a piece of Stockhausen's called Refrain. I only realized later that this was Stockhausen's "Feldman piece" just as Stimmung was his "LaMonte Young piece". (Reich 2002, 202)
However, another precedent for Stimmung is an unfinished work by Stockhausen himself, begun in 1960 and titled Monophonie, which was to have consisted of the single note E♭ (Toop 2005, 39). Igor Stravinsky, on the other hand, traces Stimmung's one-note idea back to Henry Purcell's Fantasy upon One Note, and its time-scale to Wagner's Götterdämmerung, while at the same time observing that this time-scale "indicates the need of a musical equivalent to the parking meter" (Stravinsky and Craft 1969, 94–95).
