Digesting food.

Smooth muscle is found in the walls of hollow organs (e.g., the gastrointestinal tract) and produces involuntary actions like peristalsis. Playing a piano and walking use voluntary skeletal muscle; pumping blood is done by cardiac muscle (the heart), though blood vessels themselves contain smooth muscle for constriction/dilation.
