| ← 1058edo | 1059edo | 1060edo → |
1059 equal divisions of the octave (1059edo), or 1059-tone equal temperament (1059tet), 1059 equal temperament (1059et) when viewed from a regular temperament perspective, is the tuning system that divides the octave into 1059 equal parts of about 1.13 ¢ each.
1059edo is inconsistent to the 5-odd-limit and harmonic 3 is about halfway between its steps, lending itself to a 2.9.5.7.13 subgroup interpretation.
103 steps of 1059edo represent a continued fraction approximation for the secor generator interval in the form of 46/43. In the 2.3.5.7.11.23.43 subgroup this results in a 329 & 1059 temperament. The comma basis for such (assuming both patent vals) is 1376/1375, 2646/2645, 172032/171875, 16401231/16384000, 51759729/51536320.
