379 equal divisions of the octave (abbreviated 379edo or 379ed2), also called 379-tone equal temperament (379tet) or 379 equal temperament (379et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 379 equal parts of about 3.17 ¢ each. Each step represents a frequency ratio of 21/379, or the 379th root of 2.

Theory

Using the patent val, the equal temperament tempers out 2401/2400, 5120/5103, and 10976/10935 in the 7-limit; 5632/5625, 6250/6237, 14641/14580, 42875/42768, and 43923/43904 in the 11-limit. It supports hemififths and subneutral.
