Art Lesson: Rhythm. Rhythm supplies the discipline that controls the eye as it moves around a painting. Rhythm helps the eye to move easily from one object to another and creates a harmony that tells the eye everything belongs to a unified whole. Wyland demonstrates how rhythm is visually communicated in his turtle composition. Wyland Tip: Sea turtles are turtles found in all the world's oceans with the exception of the Arctic Ocean, and some species travel between oceans.
