A rest chord serves a crucial function in music theory, primarily associated with the concept of resolving active chords. Active chords, which create tension, often seek resolution to provide a sense of closure or completion within the musical phrase. When a rest chord is employed, it provides a pause or break from this tension, allowing the music to transition smoothly into a more stable state.

This resolution is particularly important in tonal music, where the movement from dissonance (active chords) to consonance (rest chords) is a fundamental aspect of musical structure. By offering a resting point, the rest chord can help clarify the harmony and prepare the listener's ear for subsequent musical events.

In contrast, the other options do not accurately reflect the primary role of a rest chord. While tension creation, key signature establishment, and emphasizing harmony changes are important aspects of musical composition, they do not define the main purpose of a rest chord. Instead, focusing on its function in resolving active chords highlights the essential role that rest chords play in shaping musical narrative and flow.
