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.

The landscape family of rank-3 temperaments tempers out the landscape comma, 250047/250000.

Considered below is house, besides the 7-limit temperament. Discussed elsewhere are odin and tyr.
