It has been proposed that <em>Abstract Speed + Sound</em> was the central section of a narrative triptych suggesting the alteration of landscape by the passage of a car through the atmosphere. The related Abstract Speed and Abstract Speed—The Car Has Passed would have been the flanking panels. Indications of sky and a single landscape are present in the three paintings; the interpretation of fragmented evocations of the car’s speed varies from panel to panel. The Peggy Guggenheim work is distinguished by crisscross motifs, representing sound, and a multiplication of the number of lines and planes.
