What characterizes the harmonic minor scale?

• A. It raises the seventh degree by a half step to create a leading tone toward the octave
• B. It lowers the seventh degree by a half step
• C. It raises the seventh degree by a half step to create a pull to the octave
• D. It uses the same pitches as the natural minor

Answer: (C)

Raising the seventh degree in a minor scale creates a strong pull to the tonic, giving the scale a leading-tone effect toward the octave. By elevating that note by a half step, the interval from the seventh to the octave becomes a half step, which makes the dominant function want to resolve upward to the tonic, producing that urgent, convincing pull you hear in harmonic minor harmony. This is what sets harmonic minor apart from natural minor (where the seventh stays lowered) and from melodic minor (where other degrees are altered as well). So the defining feature is the raised seventh that creates that pull to the octave.
