1583 equal divisions of the octave (abbreviated 1583edo or 1583ed2), also called 1583-tone equal temperament (1583tet) or 1583 equal temperament (1583et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 1583 equal parts of about 0.758 ¢ each. Each step represents a frequency ratio of 21/1583, or the 1583rd root of 2.
Theory
1583edo is consistent to the 9-odd-limit. Using the patent val, it tempers out 2401/2400, [36 -16 -7 2⟩ and [9 21 -17 -1⟩ in the 7-limit; 2401/2400, 172032/171875, 766656/765625 and 387420489/387200000 in the 11-limit. It supports empress and vili.
