“….The title refers to the tracing (graphing) of the movement of “particles” within “cloud chambers” as they rebound off one another and thereby influence each other’s actions…..”
HODOGRAPH I (1959) was composed in the spring of 1959 for the Darmstadt festival of that year. Luigi Nono was to give a lecture on notation and formal processes and suggested that I write this work for Severino Gazzelloni, David Tudor and Christoph Caskel, each of them an outstanding soloist.
The notation is primarily “proportional” (highly specific and controlled but with slightly flexible rhythmic articulation) but there are also three 15-second “graphically notated” sections in which my graphic line-drawings are the basis for improvisation by the performers. [View additional graphically notated sections.] In effect, three collaborative cadenzas between my “implications” and the performer’s spontaneity.
Piano/Celeste is one player. Percussion is orch. bells (Glockenspiel) marimba, vibraphone.
Commissioned by Luigi Nono for Darmstadt Festival, Germany.
