Make every moment count. In the middle of practicing a routine, freeze. If so, you re developing a great projection of attitudes. If not, become aware of the mistake, and always make a conscious effort to fix it. Your next step in character development is developing a clown walk.
Most clowns have their own identifiable, stylistic ways to move.
Your walk is closely connected to your attitudes, your overall image, and the nature of your clown. People will associate your walk with your clown just as they do with Charlie Chaplin and Groucho Marx. Start by picking an attitude. Walk around the room in that attitude as if you were a statue coming to life. Change your body position so you may walk easily, but keep the essence of your attitude.
