376 equal divisions of the octave (abbreviated 376edo or 376ed2), also called 376-tone equal temperament (376tet) or 376 equal temperament (376et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 376 equal parts of about 3.191 ¢ each. Each step represents a frequency ratio of 21/376, or the 376th root of 2.
376edo is consistent up to the 11-odd-limit, but the error of the harmonic 7 is quite large, though it approximates the 5-limit very accurately. In the 5-limit, it supports gammic, kwazy, lafa and vulture temperaments. Using the patent val in the 11-limit, it supports the octoid temperament, and the rank-3 temperaments hades, hanuman, indra and thor.
