CD Imaginary Day, track 3: The Mixolydian Mode - Part One, organ Westerkerk Amsterdam

The atmosphere is exalted, with the vox humana producing strange cries of joy and agony. The sketches allow opportunities for improvisation, but certain melodic and structural features should be strictly observed. For instance, the first three phrases and the final phrase always begin with a characteristic broken triad. The amount of improvisation can be judged by comparing this piece with The Mixolydian Mode - Part Two
