Mossenmark had gotten a kind of score constructed that basically was two wooden boxes with seven tracks and marbles in each.
Every track had the same meaning as a white key on a clavier instrument.
These marbles was put in motion and depending on where they stopped, the position of the marbles created the rythm and tones according to one another.
As this got performed the marbles got in motion again.

The first performance was in Copenhagen, Denmark, in 1995 by musicians Geir Draugsvoll and James Crabb.
