Herbstmusik (Autumn Music) is a music-theatre work for four performers composed by Karlheinz Stockhausen in 1974. It is Nr. 40 in his catalogue of works, and lasts a little over an hour in performance.
Herbstmusik was written in March 1974 (Stockhausen 1978, 246) and was premiered in the Großer Glockensaal in Bremen on 4 May 1974, by the score's three dedicatees, Péter Eötvös, Joachim Krist, and Suzanne Stephens, along with the composer himself (Griffiths 1974b, 777).
It is an early step in a series of works from the 1970s exploring theatrical elements in music, progressing from Trans and Inori through Musik im Bauch, Atmen gibt das Leben, and Sirius and leading ultimately to the opera cycle Licht (Maconie 2005, 371; Toop 1998, 91–92).
It is the only composed example of a larger project of "scenes from daily life", itself part of an even more general Prinzip des Ganzen (holistic principle) formulated for a grand but unrealised project provisionally titled Oper (Opera), sketched in 1968–69 (Toop 1998, 100–102). At the same time, it is an attempt to preserve endangered sounds and customs of the harvest season in Stockhausen's country homeland, the Bergisches Land east of Cologne (Maconie 2005, 366). Stockhausen explained that, when composing this work,
I looked for a musical link between autumn and the typical sounds which accompany that season, noises with an emotive resonance, …The reassuring sound of dry leaves, the sound of rain, the sound of rotten wood crushed beneath the foot or in the hand, the distant banging when something is being nailed down. (Tannenbaum 1987, 81)
Herbstmusik was written for the Oeldorf Group, a musicians' collective founded by Stockhausen’s then assistant Péter Eötvös when he first moved from Hungary to Germany in early 1971. Stockhausen had helped him to find a farmhouse in Oeldorf, a component village of the Gemeinde Kürten, not far from Stockhausen's own home. Together with the cellist Gaby Schumacher, flautist David C. Johnson, and violist Joachim Krist, Eötvös organised a regular summer concert series held in the barn attached to the farmhouse. It was in this barn that rehearsals were begun for Herbstmusik, with Eötvös, Krist, Stockhausen, and the American clarinettist Suzanne Stephens, who was visiting to perform in one of the Summer Night Music concerts. The rustic atmosphere was evidently an essential element of the work, which did not later transfer successfully to the concert hall (Kurtz 1992, 200–201).
There are four movements, which are played without a break:
- Ein Dach vernageln (Nailing a Roof): duo with accompaniment
- Holz brechen (Breaking Wood): quartet
- Dreschen (Threshing): trio
- Laub und Regen (Leaves and Rain): duo
Because the visual-dramatic nature of a performance is so evident, Stockhausen calls special attention to the sounds in the first movement: "Please listen to the sound of nailing. … Perhaps you will not have noticed that this is music". The sounds of the leaves in the last movement also constitute "music which perhaps only a few have experienced—and if as children, they probably have forgotten it (Stockhausen 1978, 246–47).
First movement 
The first movement is "literally a two-part polyphony of nailing boards into the roof of a wooden shed" (Maconie 2005, 367). The score specifies that the two players use a type of roofing (or carpenter's) hammer commonly used in Germany, with one long, tapered point. In addition to ordinary nailing, "all timbres that can possibly result from the contact between hammer or fingers with the nails or wood should be musically exploited" including stroking the heads of different-sized nails with the hammer, quivering the tapered point of the hammer rapidly between two nails or rows of nails, sustained pattering of the broad side of the hammer on two nail heads, or rapid "trilling" of the hammer on a nailhead. These varied sounds follow a formal process in five stages, leading from ordinary nailing to a final, very delicate phase with "individual short trills, soft rebounds, … and magically iridescent timbres". The main, nailing duet is accompanied intermittently by a clarinetist who practices fragments of the melodic formula that will figure later in the fourth movement. The two roofers occasionally whistle bits of what they hear the clarinetist play. This movement should have "a strong formal effect, and communicate an impression of absolute precision" (Stockhausen 1977, 19–22, 37–40, 55–58).
Second movement 
After finishing the roof, all four performers take their places on chairs, light a campfire, and proceed to break small branches and twigs, starting with the larger pieces and proceeding toward the thinner ones (Herbort 1974). This process falls into ten phases, ending with a ritardando of clicking and rustling sounds resembling the "very bright crackling of a fire". Throughout the movement, the ensemble playing should resemble that of a string quartet (Stockhausen 1977, 24–25, 42, 60–61).
Third movement 
The threshing trio is divided into thirteen phases (Stockhausen 1977, 25–27, 43–45, 62–64) The action of beating the grain produces an overall change of sound away from an opening crispness of sound (Maconie 2005, 368). The threshers alternate working singly, in pairs, and all three together, synchronously and in rotation, miming conflict with each other and reconciliation (Herbort 1974).
Fourth movement: "Laub und Regen" 
The final movement of Herbstmusik falls into nineteen phases, beginning with a scuffle between a man and a girl in the dry leaves. A rain shower soaks both the leaves and the performers, after which they bring out their instruments (a clarinet and a viola) for the concluding eight phases, consisting of a "final duet" (Stockhausen 1977, 28–30, 46–48, 65–67).
The duet for clarinet and viola that closes the fourth movement can be played on its own as a concert work. In this form, it is given the original title of the entire last movement of Herbstmusik, Laub und Regen, and bears the work number 40½ in the composer's catalog (Stockhausen 1978, 247). This reversion to conventionally notated, composed-out music unites two of Stockhausen's characteristic devices, process composition and formula composition (Conen 1991, 40).
The melodic formula that lies at its base was written as an example during a composition seminar. When it initially is presented in the first movement, it is marked "gut zum Mitpfeifen" (good for whistling along with), a remark aimed at the actions of the two roofers. The formula contains fifteen notes divided into five segments of 1 + 2 + 5 + 3 + 4. The durations of the notes within these segments are measured in quavers: 1, 1+2, 5+3+2+4+1, 2+1+3, and 3+1+2+4. Rests at the end of each segment are also serially arranged, 3+5+1+4+2 quavers. Added to the durations of the preceding sounding notes, the five segments come to 4 + 8 + 16 + 10 + 12 quavers. In the clarinet-viola duet, this formula is first presented in its plainest form, and then is subjected to a succession of elaborations resembling the method followed in Mantra, only in this case the duet texture permits the formula to be presented simply in one instrument, while the other embellshes it. Despite the elaborate serial system used to produce it, the result recalls Béla Bartók's Contrasts (Toop 1976, 89–90).
The overall form of Herbstmusik therefore begins with everyday working sounds, upon which some melodic tones are superimposed. The pitched sounds later establish themselves in opposition to the noise. In the fourth movement the clarinet melody is heard without accompanying noises, and from this single-voice melody a two-part texture evolves, with a theatrical motivation: The woman clarinet player teaches her tune to the violist. The violist reflects on a more local level the formal process of the whole work. He begins with noise, represented by awkward playing, but gradually learns the melody. In this way the piece that had begun with nailing noises leads eventually to melody and simple polyphonic interaction (Frisius 2008, 287).
A somewhat more complex shape is suggested by regarding the form as the interaction of four evolutionary processes in different frequency bands (Maconie 2005, 367):
At the 1974 premiere in Bremen, a rock band in the ground-floor pub was loud enough to drown out the amplified sounds of breaking twigs during the second movement, during which members of the audience shouted encouragement and joined in to help break some of the larger, more stubborn branches, which were passed around the hall. By the time the performers had gotten well into the threshing scene, a member of the restless audience called out to the flailing trio, "How 'bout a beer break?" (Herbort 1974). Finally, the audience was incensed by the tumbling in the hay of the concluding movement, though one witness found it "innocently adolescent" (Toop 1998, 104). Even a sympathetic critic could only conclude by quoting the character Gustav von Aschenbach in Thomas Mann's Death in Venice: "Music is the most ambiguous of all the arts" (Herbort 1974).
When Herbstmusik was next given at the second Rencontres Internationales d’Art Contemporaine in La Rochelle on 28 June, one critic savaged it as "the lowpoint of a uniquely varied career", finding the earlier Alphabet für Liège a much more subtle and rich exploration of the "'musicalization' of everyday activity" (Griffiths 1974a; Griffiths 1974b, 777).
It was performed for a third time at the Darmstädter Ferienkurse shortly afterward, when a reviewer chose only to mention that it included a "delightfully tuneful duet for violin and clarinet at the end" (Hill 1974, 31).
A later writer detects a sense of mischief in Stockhausen’s deliberate transposition of a non-visual, radiophonic sound play into a theatrical setting, where the visual element is guaranteed to be misconstrued. From this perspective, the "documentary … scenic sound-actions" of Herbstmusik are regarded as showing the composer "at his most engaging and self-effacing", and are praised for their "truth and moral concreteness" which make a "refreshing change from the preciousness of conventional virtuosity". The closing duet in particular is seen as "charming and witty", with "an attractive lightness of touch" (Maconie 2005, 368–69).
