Horwell family

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 horwell family of rank-3 temperaments tempers out the horwell comma (monzo: [-16 1 5 1⟩, ratio: 65625/65536).
