Harmonic Armatures Applied to Still Life Paintings

The Greek mathematician Pythagoras (ca 570–ca 490 BC) discovered a relationship between numbers (specifically, proportions) and sensory perceptions that are pleasing to our ears and our eyes. In a word, we respond positively to intervals of one third, one quarter, one half, two thirds and three quarters. The harmonic armature is one of several compositional devices based on mathematic or geometric principles, such as the golden mean and root rectangles.

Above you see a harmonic armature applied to my painting Counterweight. First I drew the lines connecting opposite corners of my surface. Next I measured and marked the midpoint of each side of my surface. I then added diagonal lines connecting midpoints to each other and midpoints to corners. Notice that key components of my composition are on or near the line intersections, all of which mark quarters or thirds of either the horizontal or vertical dimension. Keeping the placement of the key points of this armature in mind can help you as you set up a still life.

I used the concept of the harmonic armature to set up my still life Favorites (below).
