'Early One Morning' is a major example of the kind of sculpture - light, airy and open-form - which Caro had begun to develop by 1962. In this work, Caro's arrangement of planes and lines along a horizontal axis gave greater freedom in creating different rhythms and configurations. The work has no fixed visual identity and no single focus of interest. Rather, it unfolds and expands into the spectator's space, its appearance changing with the viewpoint. The individual elements are unified by the bright red colour and Caro sees the way they cohere, making a sculptural whole, as being like the relationship of notes within a piece of music.
