The true test for this chapter is in the actual presentation of the speech. Like voice and diction, understanding what makes a speech effective without practice is insufficient. Merely knowing the best form for a golf swing is useless unless put into practice; and practice reinforces the knowledge. Comprehending the rules for driving on the road is moot (and/or dangerous) if the rules are not obeyed in practice. The same is true for this chapter. Practice speaking will make you a more effective speaker!
A speech is poetry: cadence, rhythm, imagery, sweep! A speech reminds us that words, like children, have the power to make dance the dullest beanbag of a heart. ~Peggy Noonan
