Repeating-pattern sensitivity cannot support transposed-pitch comparison
Evidence
This shows that although listeners may become sensitive to a repeating pattern after only 1.5 repetitions (Barascud 2014 ), they are unable to use this pattern for comparison with transposed versions of the pattern. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5263 (

Each trial consisted of four patterns separated by 700 milliseconds (ms) silence, and each pattern consisted of six tones. Three of the patterns had the same sequence of pitch intervals (standard pattern); the last pitch interval of either the final or the penultimate pattern of the trial deviated from the other three. A different standard pattern was delivered on each trial and no pattern was used more than once in the experiment. Patterns were generated by randomly selecting a set of five intervals, with the restrictions that each interval should only occur once within a pattern, and two intervals with same magnitude but opposite sign should not follow each other immediately in the sequence (to prevent the occurrence of repeated tones in the pattern). — Dijk, Pim van, Physiology, Psychoacoustics and…, 5297 (
