Aug 29, 2018· The (0,1) Mode. The animation at left shows the fundamental mode shape for a vibrating circular membrane. The mode number is designated as (0,1) since there are no nodal diameters, but one circular node (the outside edge). The (0,1) mode of a drum, such as a tympani, is excited for impacts at any location on the drumhead (membrane).
