Which statement about chromatic notes is true?

• A. Notes that always belong to the key.
• B. Notes that are reduced in pitch to half steps.
• C. Notes that introduce non-diatonic tones borrowed from outside the key.
• D. Notes that imply atonality.

Answer: (C)

Chromatic notes are pitches that do not belong to the key’s diatonic scale and are used to color melodies and harmonies by moving in semitones. They usually appear as altered notes borrowed from outside the key, such as from a parallel key or a neighboring scale, to create chromatic color and smoother voice-leading. That’s why the statement describing chromatic notes as introducing non-diatonic tones borrowed from outside the key is the best fit: it captures the idea that chromatic notes bring in pitches not part of the key you’re in. For example, in C major, adding C# between C and D or using Ab somewhere in a melodic line introduces chromatic color. The other ideas describe notes that stay within the key, or focus on semitone changes without implying borrowed color, or refer to atonality, which isn’t what chromatic notes inherently convey.
