Tuning map: Difference between revisions
Cmloegcmluin (talk | contribs) adding section for units to various temperament matrix pages, which I hope will help readers understand how they fit together |
Cmloegcmluin (talk | contribs) less strong language about units |

A '''tuning map''' represents the tuning of a [[regular temperament]]. It can take a vector representation of an interval ([[monzo]]) as input and outputs its pitch, usually measured in cents or octaves. | A '''tuning map''' represents the tuning of a [[regular temperament]].

A tuning map has one entry for each [[formal prime]] of the temperament, giving its size in cents or octaves (or any other logarithmic pitch unit). | A tuning map has one entry for each [[formal prime]] of the temperament, giving its size in cents or octaves (or any other logarithmic pitch unit). | ||
It may be helpful, then, to think of the units of each entry of a tuning map as c/p (read "cents per prime"), oct/p (read "octaves per prime"), or any other logarithmic pitch unit per prime. | |||

A '''generator tuning map''' is like a (temperament) tuning map, but each entry gives the size in cents or octaves of a different [[generator]], rather than of a formal prime. | A '''generator tuning map''' is like a (temperament) tuning map, but each entry gives the size in cents or octaves of a different [[generator]], rather than of a formal prime. | ||
