Gesture

Gesture is the use of your body's movement in presentation.  The gestures your body makes are given a great deal of attention from the audience throughout a presentation.  A gesture as simple as a slight hand movement can convey a completely unique message for the audience.  The most important part of gesture use is the timing in which a presenter makes his or her actions more extreme.  The elocutionist ideal would refer to this timing of gesture as "frequently advantageous and necessary, especially at commencement, or when an argument is concluded, or to relieve the monotony of demonstration" (Voice, Speech, and Gesture, a Practical Handbook to the Elocutionary Art, p. 155).  Eddie Murphy's bit on the icecream truck is a perfect example of this timing of gesture.  His moments of brief exposition are followed up by spastic, chaotic movements that represent children  losing their minds.
