The '''2190 equal division''' divides the octave into 2190 equal parts of 0.5479 | The '''2190 equal division''' divides the octave into 2190 equal parts of 0.5479 [[cent]]s each. It is is a very strong 13-limit system; no smaller division has a smaller 13-limit [[Tenney-Euclidean temperament measures #TE simple badness|relative error]], and nothing beats it until [[2684edo|2684]]. A basis for the 13-limit commas is {9801/9800, 10648/10647, 105644/105625, 140625/140608, 196625/196608}; also tempered out are 123201/123200 and 151263/151250. | ||
