This geometric composition features a grid-like pattern of thick black lines intersecting at right angles, creating distinct sections across the canvas. Within these sections, blocks of bold primary colors - yellow, red, and blue - interact with areas of off-white. Several rounded rectangular shapes in black appear to float within the grid structure, suggesting musical notes or sound waves given the work's title. The color blocks have a weathered, textural quality, with visible brushstrokes and areas where colors seem to fade or blend into one another. The overall effect creates a rhythm across the surface, with the rigid vertical and horizontal lines contrasting against the softer, organic edges of the color fields within each compartment.
