The equal temperaments supporting a regular temperament also characterize that temperament. | *Various regular temperaments and the equal temperaments supporting them.

**(The appendix gives proofs that the algorithms she uses work; however she didn't have the modern algebraic language to describe what in effect she was doing, making the treatment mathematically less clean than it could have been.) | **(The appendix gives proofs that the algorithms she uses work; however she didn't have the modern algebraic language to describe what in effect she was doing, making the treatment mathematically less clean than it could have been.) | ||
**She describes a temperament as a span of unison vectors/commas (Note: The commas generate the kernel characterizing a regular temperament relative to the JI space. There are multiple valid generating sets that generate the same kernel, thus multiple comma-sets that characterizes a temperament.) | **She describes a temperament as a span of unison vectors/commas (Note: The commas generate the kernel characterizing a regular temperament relative to the JI space.
