1301 equal divisions of the octave (abbreviated 1301edo or 1301ed2), also called 1301-tone equal temperament (1301tet) or 1301 equal temperament (1301et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 1301 equal parts of about 0.922 ¢ each. Each step represents a frequency ratio of 21/1301, or the 1301st root of 2.
