3/4-comma meantone is a tuning of meantone where the fifth is flattened by 3/4 of the syntonic comma, producing a fifth of 685.825 cents. This is approximated well by 7edo.
In terms of how just intonation intervals are mapped, 3/4-comma meantone is severely inaccurate within a meantone framework, particularly in terms of its 5/4. It might make more sense to interpret it as a different 5-limit temperament instead of meantone: deeptone. 3/4-comma’s fifth works better as a deeptone generator.
One way of extending deeptone into the 7-limit, 11-limit and 13-limit is the jamesbond temperament.
