In equal temperament, what is the relationship between enharmonic spellings like Ab and G#?

• A. They refer to the same pitch
• B. They refer to different pitches
• C. They must be in the same octave
• D. They can only refer to microtones

Answer: (A)

In equal temperament, enharmonic spellings like Ab and G# refer to the same pitch. The octave is split into 12 equal semitones, so the note one semitone below A is the same sound whether you call it Ab or G#. They correspond to the same frequency and, within the same octave, occupy the same position on the keyboard. The choice of spelling depends on musical context, not on producing a different pitch. If you move to a different octave, they would describe different pitches by register, but the enharmonic relationship within a given octave remains that they are the same sound.
