The Importance of the Armature of the Rectangle
Throughout this website, I repeatedly refer to the armature of the rectangle. For an artist to improve their visual literacy skills, they should never underestimate the importance of familiarizing themselves with this concept. The armature is, in effect, the foundation that supports an artist's content and ideas while arranging them in an organized manner so that the viewer can effectively read the presented work of art regardless if it's a drawing, painting, photograph, or piece of sculpture.
The below image by Johannes Vermeer, called “The Astronomer,” demonstrates the application of the basic 14 line armature that master painters use to create compositions. An artist that expects to achieve mastery in their craft should memorize the construction of this armature and employ it with regularity and consistency in their body of work. It’s also important to note that this armature directly relates to the musical scale of composition.
The sine waves in the image above demonstrate the geometry that occurs in music and how it relates to the armature of the rectangle below. Notice the ½, ⅓, ⅔, ¼, ½, and ¾ divisions.
The above image shows the harmonic divisions in the 14 line armature of the rectangle.
