In memoriam Franz Richter Herf ()

From 1979 thru 1983, Franz Richter Herf was principal of the Mozarteum University Salzburg, and in 1981, founder of the International Ekmelic Music Society.
As from 1970, he and Rolf Maedel devoted themselves to research and systematization of microtones. This finally led to the development of the Ekmelic Music.

The composition is based entirely on the production of vocal harmonics over a B Major Seven Nine Chord and uses overtones as a primary element. By gradual transformation / assimilation of 51 rhythmic models the singers weave a rhythmic polyphonic sound texture.
