A tessellation or tiling of the plane consists of using one or several types of tiles to fill it. The Sumerians were already using them to decorate palaces and other buildings in 4000BC.
In the Roman tessellation pictured above, the three sides of each cube (shown in light, medium and dark tones) can represent various aspects of elements such as pitch, range, duration, dynamics, style and so forth. A path can be created through the tessellation representing a movement or direction of travel; or maybe a series of adjacent repeating patterns. Rotated through an angle, the cubes also become a stairway.
