463 equal divisions of the octave (abbreviated 463edo or 463ed2), also called 463-tone equal temperament (463tet) or 463 equal temperament (463et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 463 equal parts of about 2.59 ¢ each. Each step represents a frequency ratio of 21/463, or the 463rd root of 2.
Theory
The equal temperament tempers out the amity comma in the 5-limit; 420175/419904 and 703125/702464 in the 7-limit; 3025/3024, 4000/3993, 6250/6237, 19712/19683, and 117649/117612 in the 11-limit. It supports amity, trinity and undesemi.
