God is in the details of this wordless 45-minute work by collaborative movement-theater troupe Sprung. The subject is a happy one: the piece's starting point was the sentence "Two people choose to be together." And the show is defined, for better and worse, by its lightheartedness--even the seven deft performers' movements are light and quick. Scenes in which they wait for a bus or take their dogs to the park are remarkable for their musicality, acute observation, and humor. A scene set in a bar is darker and more thoughtful, as minute gestures--a reach between the legs of a chair, a glare--express yearning or rejection. Using a clever sound mix yjiulio;and minimalist set, Abound explores the dynamics and repercussions of romantic relationships through the fundamentals of physical expression: gaze, body alignment, timing, tiny adjustments in personal space. Problem is, it doesn't do much else. Through 5/21: Fri-Sat 8 PM. Chopin Theatre, 1543 W. Division, 773-456-5687. $15.
