An informative or persuasive speech may be effective enough in getting across your message if you follow the basic rules. But if you want to make it more memorable and moving — more eloquent, with features and phrases that stick in the mind and uplift the soul — there are a number of tactics you should master. One is to tell stories that illustrate your points. Another is to quote the colorful and insightful observations of others (preferably the famous) about your topic. Citing poems can also provide an artistic flourish that touches the emotions.
