The Kartvelian scales generalize the traditional scale of Georgian folk music to divide the perfect fourth and fifth into arbitrary numbers of equal steps. This scale, called “untempered” on Wikipedia, is more properly described as the first known well temperament in music history. The fifth, or conversely the fourth, will be an interval of the corresponding edo which may generate 2L 3s or 3L 2s and normally stands within one edo degree of 3/2.
