The musical examples for Cantometrics had not been chosen randomly, however, but for their representativeness, following the scholarly guidance of specialists who had studied the regions and /or supplied the audio or film clip samples. This was done because it was found that style tends to be very repetitive, and in most instances relatively few examples captured the stable performance norms, so that in most cases, coding many examples per culture yielded little new information. Lomax and Grauer settled on about ten examples per culture for Cantometrics, which had the largest dataset. Ten examples per culture usually sufficed, although for some cultures one or more sub-styles needed to be sampled as well.
