I create visual representations of music. The painting that I have contributed to the Patron's Party is based on a Baroque Keyboard sonata by Domenico Scarlatti, known by its catalog number K533. The title is The Boundary Layer. The pattern of colors tracks the harmony in a section of the sonata. Though true to their placement in the sonata, the colors of the harmonies have been enhanced to depict an imaginary layer between a bird's wing and the air it flies through during a summer day. This boundary layer has an aerodynamic function and although it can be studied, explored, and imagined, it permanently separates the bird from the sky.
