(A) Schematic of the trial structure for Experiment 3. Participants heard two melodies with note-to-note steps of +1 or -1 semitones, and judged whether the two melodies were the same or different. The second melody was always transposed up in pitch relative to the first melody.

(B) Results from Experiment 3. Performance was measured as the area under Receiver Operating Characteristic (ROC) curves. Error bars denote standard error of the mean.
