3 movements; 4 mallets; Vibra + Tria.; difficult - Featured at PASIC 2006 Focus Day, DUO consists of three movements. Each movement is announced with the appearance of the triangle. The third, shortest movement is linked with the second one without pause. The basic idea is a kind of dialogue between the two instruments, as an imaginary conversation with different moods, harmonies and disharmonies between these two 'living creatures' - flute and vibraphone. The piece was written in 1998.
