Rhythm in architecture refers to the repetition or alteration of elements at regular intervals, creating a sense of movement or flow. This can be seen in architectural elements like columns, windows, and doorways that are spaced regularly.
Just like music, rhythm in architecture establishes a visual "beat" through repeated patterns. It helps to guide the viewer’s eye and create a cohesive design.
Contrast, monotony, and emphasis are other design principles but do not specifically relate to the concept of movement through repetition or intervals in the same way rhythm does.
