Plus-Minus, 2 × 7 pages for realisation, is a composition for one or several performers by Karlheinz Stockhausen, first written in 1963 and redrafted in 1974. It is Nr. 14 in the composer's catalogue of works, and has a variable performing length that depends on the version worked out from the given materials. The score is dedicated to Mary Bauermeister.
Plus-Minus is a "polyvalent process composition" (Kurtz 1992, 133), designed as a project for the composition students attending the first Cologne Courses for New Music, held at the Rheinische Musikhochschule in October to December 1963. In it, various compositional premises of Stockhausen’s are presented in such a way as to enable the most radically different concrete results (Frisius 2008, 149).
Plus-Minus was composed in September 1963 while Stockhausen was in Siculiana, preparing for what proved to be an aborted performance of Momente at the Palermo Festival (Bauermeister 2011, 129–30; Kurtz 1992, 128):
In 1963 I spent a couple of weeks in Sicily by the seashore, and as I couldn't take a lot of paper with me I tried to hide in the shadow of a rock and think clearly about a new piece, and Plus-Minus is what emerged. (I'd discussed all the possible transformations of the seven 'musical types' that occur in the score with Mary [Bauermeister], and we drew them in the sand together. (Cott 1973, 153)
The piece represents an extreme instance of the new, open type of composition Stockhausen was developing at the time, and evolved from a number of conversations with Mary Bauermeister in Siculiana and Palermo (Bauermeister 2011, 130; Kurtz 1992, 128). Stockhausen's intention was to enable a music that reproduces itself, within a strict framework. Twenty-five different versions were made by the students in 1963, for a wide variety of forces: one for four harps, one for three harps and two pianos, one for recorders and children's choir, one for large orchestra, one for percussion and piano, one for two percussionists, and another for choir and chamber orchestra (Cott 1973, 153, 158; Stockhausen 1971, 42).
The first public performance was given in Rome in June 1964 by Cornelius Cardew and Frederic Rzewski, each of whom realised one page of the score (Fox 2000, 19). When Stockhausen heard a tape of this performance, he was astonished that sounds he had usually avoided were being employed, exactly according to the score’s specifications, to achieve a highly poetic quality (Stockhausen 1971, 42–43).
The course of the work is based on polarities of attraction and repulsion, of growth and decay. Material is systematically accumulated and eroded, in a process resembling a game of chess, where central and secondary notes either expand and proliferate, or are reduced until they disappear (Maconie 2005, 250–51). These oppositions include, for example, the confrontation of materials having definite pitch with others of indeterminate pitch. The score systematically catalogues its materials into (Frisius 2008, 149–50):
- Seven types of events
- Seven different ways of placing ornaments relative to a central sound (1) before, (2) simultaneous, (3) after, (4) before and after, (5) simultaneous and after, (6) before and simultaneous, (7) all three
- Seven different formal units of the piece
- Seven different basic types of grouping notes
- Seven possible formal constellations for one complete realisation of seven formal units
- Seven possible temporal combinations of adjacent events
- Three types of rests separating events (long, medum, short)
- Three types of superimposition
- Seven possible overall characteristics of a given layer, (1) pitched sound, (2) noise (3–6) mixed pitch and noise (each one hard or soft), or (7) free
There are seven so-called "symbol pages", on which all musical events are represented by ideograms, and a second set of "note pages" on which the pitch material for the events is notated. One or several layers of events can be worked out from these fourteen pages, and be combined according to particular rules (Stockhausen 1971, 40). The types wax or wane according to the precribed plus and minus processes, up to a maximum value of +13, which can result in very long sounds. If a process of diminution continues after reaching a value of 0, the events become represented by a "negative band of sound"—a "sound wall" of noise, such as breathing or radio noise, out of which silent events are cut until a value of –13 is reached, which is total silence. At that point, the event-type in question "dies" and may not be used again in the piece (Cott 1973, 152–13).
The score of Plus-Minus is complicated, delivering the message that composing serial music is hard work (Maconie 2005, 251). The openness of the score was itself seen at the end of the 20th century as a form of control, deterring all but the most committed musicians from undertaking performances. Nevertheless, anyone making a realisation does have considerable control over the nature of the piece, and "negative-minded realisers can kill the piece, the over-positive can encourage disproportionate growth" (Fox 2000, 18–19). At the first Cologne Courses, a student composer from Iceland, Atli Heimir Sveinsson, "assassinated" Plus-Minus by deliberately discovering the quickest way to end the piece. According to Stockhausen, "There were just a few blips and blobs and then lots of silences … that was it" (Cott 1973, 158).
