Expressive phrasing is the device by which expressive emphasis can be added to the phrases, both at a local (in the sense of individual units) and global (in the sense of phrases) level. There are numerous ways this can occur in both speech and music that exhibit interesting parallels. For instance, the increase in the amplitude of a sound being played by an instrument accents that sound much the same way that an increase in amplitude can emphasize a particular point in speech. Similarly, speaking very rapidly often creates a frenzied effect that mirrors that of a fast and agitated musical passage.
