1051 equal divisions of the octave (abbreviated 1051edo or 1051ed2), also called 1051-tone equal temperament (1051tet) or 1051 equal temperament (1051et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 1051 equal parts of about 1.14 ¢ each. Each step represents a frequency ratio of 21/1051, or the 1051st root of 2.
Theory
1051edo only has a consistency limit of 3 and does poorly with approximating the harmonic 5. However, it has a reasonable representation of the 2.3.7.11.17.19 subgroup.
Assume the patent val, 1051et tempers out 2460375/2458624 in the 7-limit; 820125/819896, 2097152/2096325, 514714375/514434888, 180224/180075, 184549376/184528125, 43923/43904 and 20614528/20588575 in the 11-limit.
