What term is used for notes that sound the same but have different spellings, such as Ab and G#?

• A. Chromatic notes
• B. Relative pitches
• C. Enharmonic pitches
• D. Parallel keys

Answer: (C)

Notes that sound the same but are written with different spellings are called enharmonic pitches. In equal temperament, Ab and G# correspond to the same piano key, so their pitch is identical. The difference lies in notation and musical context: Ab fits keys and chords that use flats, while G# would align with sharps, though in practice some keys (like G# major) are not convenient to spell, so music often uses Ab instead. This distinction matters for reading, key signatures, and harmonic analysis because the spelling reveals the scale degree, interval, and function within a given key. The other terms describe different ideas: chromatic notes refer to all semitones, not to alternate spellings of the same pitch; relative pitches are about how pitches relate within a key; parallel keys are major and minor keys that share the same tonic.
