PRELUDE 19 begins with hand-painted swatches of variable colors encompassed eventually by vertical strokes of reds and blues, followed by sudden clearings which are counterpointed by sections of multiple blobs of color, these effects alternating again and again to then become contrasted with pale washes of color deepening to end on blacks.

PRELUDE 20 begins with pale washes of hand-painted tones overlaid eventually by sharp forms, a kind of sliced color becoming more and more smeared. The first two PRELUDES of this series were double printed, so that PRELUDE 21 is most characterized by the double-time of single-frame printing of extremely thick swatches of multiple colors as if in a furiously boiling cauldron.

PRELUDE 22 is a singly-printed hand-painted thick black and gold swatches of color which evolve into forms that are horizontally and vertically sliced, smeared, cut-off until color "runs" sensuously in snake-like shapes, coils, soforth.

PRELUDE 23 is doubly-printed hand-painted frames causing an effect almost as if wisps of tone were tinting the film intercut with sharp thin lines which "fatten," then, into thick crowded layers of paint, senses of great visual depth. This PRELUDE is almost a catalogue of the effects in all previous PRELUDES.

PRELUDE 24 returns to the tempo of single-frame printing. Its shapes and forms are composed of nearly black torques of ink, flickering with white and only faintly, now and again, tinged with color.
