The sound of a horse's hooves is commonly referred to as "clopping." This distinctive sound occurs when the horse's hooves strike the ground, creating a rhythmic noise that varies based on the surface and the horse's speed. In literature and film, this sound often evokes a sense of urgency or movement, enhancing the atmosphere of a scene.
