53 equal divisions of the octave (abbreviated 53edo or 53ed2), also called 53-tone equal temperament (53tet) or 53 equal temperament (53et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 53 equal parts of about 22.6 ¢ each. Each step represents a frequency ratio of 21/53, or the 53rd root of 2.

Theory

53edf corresponds to 90.6041edo, similar to every fifth step of 453edo. It is related to the regular temperament which tempers out [-44 44 53 -53 in the 7-limit, which is supported by 90-, 91-, 181-, 453-, 544-, 634-, 725-, 997-, 1087-, and 1178edo.
