4327 equal divisions of the octave (abbreviated 4327edo or 4327ed2), also called 4327-tone equal temperament (4327tet) or 4327 equal temperament (4327et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 4327 equal parts of about 0.277 ¢ each. Each step represents a frequency ratio of 21/4327, or the 4327th root of 2.

Theory

4327edo is consistent to the 11-odd-limit, tempering out 117649/117612, 50014503/50000000, 234365481/234256000 and 369140625/369098752. It supports mikkolic.
