143edo is a scale which divides the [[Octave|octave]] into 143 equal divisions of approximately 8.392¢. The 143b val provides a tuning almost identical with that of the POTE tuning for 7-limit meantone.

As 143 is 11*13, 143edo allows the [[Polymicrotonality|polymicrotonal]] juxtaposition of [[11edo|11edo]] and [[13edo|13edo]]:
== Theory ==
143edo is only [[consistent]] to the [[5-odd-limit]], and the error of the [[harmonic]] [[3/1|3]] is quite large. With the patent sharp fifth and flat 7, it supports a sharp form of [[slendric]] and [[hemithirds]] through to the [[13-limit]], while the 143b val provides a tuning almost identical with that of the [[POTE tuning]] for 7-limit [[meantone]].

If the 11edo and 13edo sub-scales share one tone (as in the diagram above), the resulting scale would have 23 tones in the octave; otherwise, it would have 24.
If the 11edo and 13edo subsets are analyzed as two scales that share the [[tonic]] and are then combined (as in the diagram above), the resulting scale would have 23 tones in the octave; otherwise, it would have 24.
