This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

An 11th-octave temperament can be described by temperament merging of edos whose greatest common divisor is 11. Although 11edo itself is not particularly accurate for low-complexity harmonics, some temperaments which are multiples of 11 are.

5-limit temperaments

Hendecapent

This temperament has a period of 1/11 octave, which represents 16/15 in the 5-limit. There are some 7-limit extensions include hendecatonic (22 & 77) and hendeca (22 & 33).
