Lets have a look at the Eleventh Step today. This step is usually used for spanning the stage and cover larger areas. It is also done in self-circles too. Some call this step to be Usi adavu or Periya Adavu. Usi adavu has emphasis on the second beat. That means after the jump the flat tap and every even flat foot contact is emphasized. Now ‘Periya’ beacuse it covers larger or bigger spaces on the dance floor.
