**2814 equal divisions of the octave** (abbreviated **2814edo** or **2814ed2**), also called **2814-tone equal temperament** (**2814tet**) or **2814 equal temperament** (**2814et**) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 2814 equal parts of about 0.426 ¢ each. Each step represents a frequency ratio of 2^{1/2814}, or the 2814th root of 2.

## Theory

2814edo has all the harmonics from 3 to 17 approximated below 1/3 relative error and it is as a corollary consistent in the 17-odd-limit.

In the 7-limit, it is enfactored, with the same commas tempered out as 1407edo. In the 11-limit, it supports rank-3 odin temperament. In the 13-limit it tempers out 6656/6655 and supports the 2.5.7.11.13 subgroup double bastille temperament.
