Joel Hagstrom: Rhythm and its Power

When talking about words, Gerardus Van Der Leeuw  makes an important mention about how the rhythm of words plays an integral part in their ability to create power and force.  Van Der Leeuw says that every "word...has an effect. But metrically organized words develop a concentrated power."  I think it would be hard to find an individual who has never been moved personally due to a presentation, whether in song or spoken word, that contains a certain energy within the "feel" of the words being used.  Some of the most effective speakers today understand the power behind the underlying rhythm created by words and how that rhythm can be effectively used to hold a greater influence over the listener.   Elegant speakers who masterfully control their rhythm and word choice hold greater influence over those who do not.  I think that while we use words to form our thoughts and present our ideas, many individuals overlook how to effectively control them and utilize the inherently present rhythm.  Musicians and poets are some of the individuals who understand the power of rhythm and can thus captivate millions of people from a wide range of cultures and social situations.  They should be used as examples about how the power of rhythmic speech can reach a much larger area of people and have a greater influence on those listening.  Are there other ways available to manipulate the power of words?  Who else besides musicians and poets masterfully use the power in words?
