| | Stockhausen, Karlheinz |
 | | To Webern's theory of presenting the notes of the chromatic scale in series, Stockhausen added the serial ordering of other musical dimensions, such as volume, duration, and tone color. |
 | | He expanded Webern's concept of points of interest to what he termed "group composition," in which several groups of materials, each having its own character, are linked together, sometimes leaving the order of presentation to the performer, as in Klavierstuck XI (1956). |
 | | Stockhausen's imaginative use of electronic and acoustic materials and elements of chance has produced such innovative works as Gruppen (1955-57), Telemusic (1966), Autumn Music (1974), and Michael's Youth (1978-79). |
