Horizon was completed in 1985 and is characterized by its dansant qualities. Most striking are the alienating discords and embellishing trills. With pulsing vitality, a climax develops in the course of this piece, ultimately ending in a reminiscence of the opening theme.

Horizon is enacted in the area between improvised and notated music. It is true that there is a score with prescribed notes, but that does not mean that the player should do something only when there are notes about and remain silent when nothing is prescribed. It will occur regularly that one remains silent when there are notes - and plays when there are none.
