Marcia e Grido

for marimba solo
composed 1990; duration 9 minutes
world premiere Ebeltoft Festival (Denmark) 1991
Gert Sørensen – marimba

The first part of the piece is composed through the use of dynamic Markovian chains. This part falls in two sections, where the first exclusively contains chords of varying duration. The first part’s second section goes into some quite virtuoso playing, where cells of melodic fragments governed by Markovian chains fulfill a preconceived form. The second part is based on the 1/f distribution.
