Answer:

A phrase, loosely speaking, is a series of movements bound together by a physical impulse or line of energy and having a discernible beginning and end. (A rough analogy can be made with the way a singer phrases a multiplicity of notes within a single breath.) Many factors work to make the spectator perceive a series of movements as a phrase. The first is the recognition of some kind of logical connection between the movements that prevent them from appearing arbitrary and isolated.
