Line, Shape, Form, Color, Value, Texture, and Space.
This painting in particular uses most of them! Lets start from the beginning. Line is incoorperated by not only the stand on the cake-holders, but the different designs on the cake. Whats a cake without shape?! Shape is a key role in this artwork. It allows us to understand what is being depicted by the artist. Form is the element of 3D and volume, the shadows of the cake on the "floor" adds this too. Color adds tone to the painting. Most of these colors are warm. Value is used by the lightness and darkness in these specific colors. Texture allows us to infer how these cakes may feel by the patterns painted. And last, space is the element of positive and negative areas.
The answer is minimalist music. Minimalist music is based in frequent repetition which have small variations of a small musical idea. Usually, it is a slowly changing common chords and common tones.
