Zwei Stücke für Klavier
Siegfried Koepf 1990
In Zwei Stücke für Klavier harmonic spaces are constituted which show specific qualities in the relation of pitch- and interval materials. The discovery and manipulation of such specific harmonic complexes are based on a comprehensive combinatorial analysis of the materials of the equal-tempered 12-tone system.
