I found this poster for a piano player’s show, by Sara Westermann, on Pinterest. The brush strokes creating the g, illustrate the movement of the piano player’s body. When pianists play, they often sway back and forth. You can see how the stroke of the g’s bowl defines the path where the man’s head is going. The descender stroke shows where his lower body is positioned. The white spaces in the stroke also help create a sense of movement.
