Final answer:
The term that describes a closed, or resolved structure in music where expectations are satisfied by the way the fourth phrase ends is a balanced structure.
Step-by-step explanation:
The term that describes a structure that is closed, or resolved, where your expectations are satisfied by the way the fourth phrase ends, and you feel no need to continue on to another phrase is balanced structure.
In a balanced structure, the musical phrases or sections are organized in a way that creates a sense of completion and closure. This can be achieved through various musical techniques such as repetition, sequence, and cadences.
For example, in a piece of music with a balanced structure, the fourth phrase might end on a cadence that provides a clear conclusion to the musical idea, leaving the listener feeling satisfied and not expecting any further continuation.
