10257 equal divisions of the octave (abbreviated 10257edo or 10257ed2), also called 10257-tone equal temperament (10257tet) or 10257 equal temperament (10257et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 10257 equal parts of about 0.117 ¢ each. Each step represents a frequency ratio of 21/10257, or the 10257th root of 2.
