701 equal divisions of the octave (abbreviated 701edo or 701ed2), also called 701-tone equal temperament (701tet) or 701 equal temperament (701et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 701 equal parts of about 1.71 ¢ each. Each step represents a frequency ratio of 21/701, or the 701st root of 2.
