523 equal divisions of the octave (abbreviated 523edo or 523ed2), also called 523-tone equal temperament (523tet) or 523 equal temperament (523et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 523 equal parts of about 2.29 ¢ each. Each step represents a frequency ratio of 21/523, or the 523rd root of 2.

Theory

523et tempers out 2401/2400 in the 7-limit; 56723625/56689952, 26214400/26198073, 78675968/78594219, 759375/758912, 496125/495616, 6250/6237, 42875/42768, 19712/19683, 1479016/1476225, 16808715/16777216, 3294225/3294172, 43923/43904, 102487/102400, and 322102/321489 in the 11-limit.
