What is the function of the dominant pitch?

• A. It is like a second gravitational center and sets melodies in motion by pulling them away from the tonic.
• B. It is the highest pitch in the scale.
• C. It always resolves to the tonic immediately.
• D. It has no influence on melodic direction.

Answer: (A)

The dominant creates a sense of forward motion and pull in tonal music. It centers on the fifth scale degree and uses chords built on that note (the dominant triad or seventh chord) to generate tension that eagerly wants to resolve to the tonic. This tension supplies direction to melodies: lines tend to move away from the tonic toward the dominant area and then resolve back, with the leading tone often stepping up to the tonic to strengthen the pull. In practical terms, in C major the G major (or G7) chord pushes the harmony toward C major, giving that satisfying arrival when the tonic is reached. The idea that the dominant is simply the highest pitch misses its real role, and it doesn’t always resolve immediately—voices may linger or cadences may vary—but the dominant’s function as a guiding, gravitational force is what best explains its influence on melodic motion.
