653 equal divisions of the octave (abbreviated 653edo or 653ed2), also called 653-tone equal temperament (653tet) or 653 equal temperament (653et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 653 equal parts of about 1.84 ¢ each. Each step represents a frequency ratio of 21/653, or the 653rd root of 2.
Theory
653edo is distinctly consistent to the 21-odd-limit. As an equal temperament, it tempers out [39 -29 3⟩ (alphatricot comma) and [-20 -24 25⟩ (counterhanson comma) in the 5-limit; 2401/2400, 65625/65536, and [7 -27 13 2⟩ in the 7-limit; 3025/3024, 41503/41472, 496125/495616, and 1953125/1948617 in the 11-limit; 2080/2079, 4459/4455, 6656/6655, 10985/10976, and 170625/170368 in the 13-limit; 1225/1224, 2058/2057, 2431/2430, 2500/2499, 4914/4913, and 11271/11264 in the 17-limit; 1445/1444, 1521/1520, 1540/1539, 1729/1728, 3136/3135, 4200/4199, and 4394/4389 in the 19-limit.
