As a composer Barbara Heller was always en route - in search of new forms of expres-sion, of possibilities of articulation, and of forms for her musical language. As an artist she always took a path toward ever-increasing openness and formal freedom, including graphic notation, tape collages, sound installations, and collaborative projects. It is sensuous, playful music that Barbara Heller composes, characterized by being both contemplative and experimental. Like a scarlet thread the idea of a "game" passes through all of her compositions. She describes the space un poco, she initiates the rules: resulting in constantly new and constantly different motion in which the figures and the sounds develop in continuously new and endlessly varied constellations.
