Through the interactions of shapes, colors, and movement, Alexander Calder revealed how opposing elements and forces could attain symbiosis in his dynamic and groundbreaking sculptures. His works often appear whimsical, yet they are carefully calibrated and composed. Gongs, dings, hums, and silent pauses add humor and sound to enliven Calder’s abstractions and bring their contrasting components together as cohesive reflections of the surrounding world.
