for violoncello solo (2007, ~8´)

Two section building bass models on the open strings (C-G-D-G, D-A) are combined with a randomly generated (but repetition-avoiding) "melody line" of complementary pitches. In changing participation of "melody" and bass a kind of very slow "waltz" is introduced. Simple generators (varied cycles of few elements) are applied to playing techniques (trills, semitone glissandos, sul pont.) and the dynamic models crescendo, crescendo / decrescendo in order to establish variation within the continously elegiac tone.
The unusual sequencing of common elements (playing techniques, dynamics), some of them with a strong tonal tendency (open strings), causes a kind of irritation I am especially interested in.
