Intuitive music
Intuitive music is a form of musical improvisation based on instant creation in which fixed principles or rules may or may not have been given. It is a type of process music where instead of a traditional music score, verbal or graphic instructions and ideas are provided to the performers (Stockhausen 1989, 113–14). The concept was introduced in 1968 by the German composer Karlheinz Stockhausen (Stockhausen 1993; Bergstrøm-Nielsen 1997), with specific reference to the collections of text-notated compositions Aus den sieben Tagen (1968) and Für kommende Zeiten (1968–70). The first public performance of intuitive-music text compositions, however, was in the collective work Musik für ein Haus, developed in Stockhausen's 1968 Darmstadt lectures and performed on 1 September 1968, several months before the first realisations of any of the pieces from Aus den sieben Tagen (Iddon 2004, 91, 99; Misch and Bandur 2001, 478; Stockhausen 2009, 3).
