Gruppen

Total Instrumentation: 109 players, 3 conductors

This large work for 3 orchestras with 3 separate conductors, is one of Stockhausen's most famous works. The title 'Gruppen' or groups refers to the 174 groups of notes that the composition is built upon. In this case a group is, according to the composer, "a particular number of notes which are joined, by means of related proportions, into a superordinate experiential quality".
