The physical arrangement of pitches in most traditional musical instruments—including the piano and guitar—is non-isomorphic, which means that a given spatial relationship between two keys, buttons, or fretted strings can produce differing musical pitch intervals. Since the nineteenth century, it has been widely considered that isomorphic pitch layouts, which do not have such inconsistencies, facilitate the learnability and playability of instruments—particularly when a piece needs to be transposed into a different key. However, prior to this paper, this has not been experimentally tested. The figure shows an example of one of the pitch layouts used in this experiment. View this paper.
