Which statement about chromatic pitches is accurate?

• A. They are used to decorate or express, not for structural harmony
• B. They form the core of the scale
• C. They determine the meter
• D. They are always diatonic

Answer: (A)

Chromatic pitches are notes outside the key’s diatonic scale; they color melodies and harmonies with tension and expression. In tonal music, the basic structure of harmony and tonal center comes from diatonic scale degrees and their functional chords. Chromatic notes tend to serve decorative or expressive purposes—acting as passing tones, neighbor tones, or borrowed tones from a parallel key—creating color and momentary coloristic tension that resolves back to the diatonic harmony. While they can influence harmony in certain contexts, they don’t form the primary framework that defines the scale or its rhythmic structure. That’s why this statement best captures their typical role: they’re used to decorate or express, not for structural harmony. The other ideas conflict with how chromatic pitches function, since they are not inherently the scale’s core, meter is a rhythmic matter, and chromatic tones are by definition non-diatonic.
