1053 equal divisions of the octave (abbreviated 1053edo or 1053ed2), also called 1053-tone equal temperament (1053tet) or 1053 equal temperament (1053et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 1053 equal parts of about 1.14 ¢ each. Each step represents a frequency ratio of 21/1053, or the 1053rd root of 2.
1053edo is consistent in the 11-odd-limit. It is a very strong 5-limit tuning where it tempers out [1 -27 18⟩ (ennealimma), [91 -12 -31⟩ (astro comma), and [92 -39 -13⟩ (aluminium comma). It supports and gives a good tuning for the quadraennealimmal temperament, as well as the 27th-octave trinealimmal.
