352 equal divisions of the octave (abbreviated 352edo or 352ed2), also called 352-tone equal temperament (352tet) or 352 equal temperament (352et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 352 equal parts of about 3.41 ¢ each. Each step represents a frequency ratio of 2^1/352, or the 352nd root of 2.

Theory

352edo is consistent to the 7-odd-limit. Using the patent val, the equal temperament tempers out 2401/2400, 15625/15552, 390625/388962, and 33554432/33480783 in the 7-limit; 3025/3024, 4375/4356, 14700/14641, 19712/19683, 41503/41472, and 131072/130977 in the 11-limit. It supports newt, world calendar, septiruthenic, enki and fortune.
