Pattern and rhythm is showing consistency with colors or lines. Putting a red spiral at the bottom left and top right, for example, will cause the eye to move from one spiral, to the other, and everything in between. It is indicating movement by the repetition of elements. Rhythm can make an artwork seem active. source
So, how does that translate visually?
White stripes are the pattern, as are the three gold dots.
The pink tubes on each of the three corners give this piece consistency and pattern, while the grey ones in the middle ground the piece as a whole.
How do you make pattern and rhythm make sense to you?
