The white of the unprinted paper divides and borders each composition, which consists of five blocks of four-coloured horizontal stripes rendered in mild shades of purple, turquoise, green, and orange. Each segment has alternating sections of harmony and contrast that allude to the flow of music. Riley manipulates the image's speed by altering the colour scheme in each block. The composition has a sense of flawless control and poise.

Despite being ostensibly abstract, Riley's art has always been the product of a deep fascination with nature and its visual manifestations. Water, soil, air, and plants are all reduced to their most basic forms in these prints. The Intervals series is a stunning representation of an artist at the height of her abilities.
