759 equal divisions of the octave (abbreviated 759edo or 759ed2), also called 759-tone equal temperament (759tet) or 759 equal temperament (759et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 759 equal parts of about 1.58 ¢ each. Each step represents a frequency ratio of 21/759, or the 759th root of 2.
Since 759 = 3 × 253, and 759edo shares its excellent perfect fifth with 253edo. However, the primes 5, 7, 11, and 13 are mapped differently. With octave stretching, one may use 2.7.11.13 subgroup, all sharp, or 2.5.17.19.23.29.31 subgroup, all tuned flat. The 759def val supports noletaland, the 282 & 759def temperament, in the 23-limit. 759edo is an amazingly accurate 2.3.37.103.229 system.
