Gamut in Composition
Gamut in composition means the artist is using a limited number of directions in their drawing, painting, or photograph. By limiting the number of directions an artist uses, it won't overwhelm and confuse the viewer. Generally speaking, most master artists will only use 5-7 different directions in a work of art. Also, in a masterpiece, those directions will come from a Dynamic Symmetry grid. Painting below, "Spring Breeze" by William Adolphe Bouguereau, demonstrating a limited number of directions.
