Subjects matched musical intervals within about 2 percent in both conditions

Evidence

For all subjects, the adjusted frequencies were somewhat flat, i.e. slightly lower than expected, leading to somewhat larger musical intervals. However, this was true for both the PT and the ZT conditions (different coloured bars). Generally, the adjusted frequencies were within about 2 % of the expected frequencies, with no systematic differences between the ZT and the PT conditions. Thus, subjects were able to match musical intervals with good accuracy for both conditions. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5408

• QUESTION: The consistent slight flatness (larger intervals) in both conditions is interesting — is this a perceptual constant or an artifact of equal-temperament expectation?
