In music, serialism is a method or technique of composition that uses a series of values to manipulate different musical elements. Serialism began primarily with Arnold Schoenberg's twelve-tone technique, though his contemporaries were also working to establish serialism as one example of...

History

Goeyvaerts composed the Sonata during the winter of 1950–51, and brought the score with him when he attended the Darmstädter Ferienkurse in the Summer of 1951. There he met Karlheinz Stockhausen

's composition seminar had considerable significance for those young composers eager to develop serial thinking. The influence of the Sonata is also evident in Stockhausen's early serial compositions (Delaere 2001), particularly Kreuzspiel

, which Stockhausen began composing on his way home from Darmstadt and finished on 4 November 1951 (Sabbe 1981, 18–19). Adorno, however, did not appreciate the qualities of the work's second movement, because he could not find any motivic coherence in it. When Goeyvaerts found it difficult to defend himself in German (a language in which he was not fluent), Stockhausen stood up for his friend, telling Adorno, "you are looking for a chicken in an abstract painting" (Stockhausen 1989, 36).

Although originally titled Sonata for Two Pianos, Goeyvaerts later sought to accentuate the innovative intent of the work by referring to it simply as Opus 1 or Nummer 1 (Blumröder 1993, 38).

Material and form

The Sonata for Two Pianos is in four movements, which are simply designated with Roman numerals and metronome markings. Movements I and II are presented in retrograde to form movements III and IV—a pattern that may have been suggested by the four sections of the first piece in Olivier Messiaen

It is among the earliest examples of multiple or integral serialism, though it is something of a hybrid work. The outer movements relapse into older patterns and do not exhibit the technical purity and perfection of structural organisation found in the middle movements (Delaere 1994, 13; Delaere 1998). It was only with his Nummer 2

 for 13 instruments that Goeyvaerts found a way of composing in which absolutely everything, from the overall form down to the tiniest detail, is governed by one and the same serial principle (Delaere 2001). The second movement in particular, with its isolated tones, is an example of punctual

, except they both include the two pitches A and E (Sabbe 1981, 7). A possible model is the fourteen-tone series serving as the theme of the variation movement in Schoenberg's Serenade op. 24 (Sabbe 1994, 59).

One technique used in the Sonata to preserve an equilibrium amongst several parameters is the "synthetic number". This term was coined by Goeyvaerts and Stockhausen to describe a homeostatic

system based on the reconciliation of tendencies, where an increase in one dimension (e.g., duration) results in a decrease in another dimension (e.g., loudness) (Sabbe 1981, 20–21). The method used in the Sonata involves combining the numerical values assigned to the elements in each of four parameters (pitch, duration, loudness, and mode of attack) such that their sum will always be 7 (Sabbe 1994, 55, 71).
