As opposed to the rigid geometries of earlier abstraction, Rondo resonates with a lyrical fluency, true to its poetic title. The painting suggests a rhythm analogous to musical composition. Surging forms and carefully balanced tonalities create a dynamic, yet harmonious tension, evoking a sense of movement both intuitive and controlled.

Rebay's profound admiration for Kandinsky is clear in Rondo, as is her belief in Rudolf Steiner's anthroposophy. This spirituality separates her work from the mostly analytical works of contemporaries such as Mondrian. As Mondrian was trying to find universal order through strict grids, Rebay's paintings breathe, pulse, and call forth an emotional reaction. The gestural nature of Rondo implies a process imbued with intuition, a spontaneous yet controlled creative act.
