You have a little more time to see Song (pictured), Jennifer Bartlett's series of enameled metal plates, at the Locks Gallery on Washington Square. It's an enormous work - 97 feet long - using "a basic black dot as a springboard to explore various compositional themes, employing the dot like notes in a melody." On view through May 24.
Bartlett is represented at an exhibition closing after this weekend at the Museum of Modern Art, "Color Chart: Reinventing Color, 1950 to Today."
Also closing soon: The Frida Kahlo show at the Philadelphia Museum of Art, which runs through May 18.
