DIA

Premiered in September 1979, DIA, with its wedge form "refers to the idea of an arrow pointing through the multidimensional musical space of the piece — the beginning of a trajectory crossing through all of it, visiting every point, but a trajectory free of any preordained form or curvature." The grand old man of Finnish Modernism Paavo Heininen (b. 1938) sees form as an idea of time and reflects it in one continuous movement with five distinct sections.
