| | Regular Temperaments |
 | | An alternative way to think of a regular temperament, which may be more useful for constructing musical scales, is to represent each note of the temperament as a combination of one or more multiples of a generator (a repeated interval of the temperament, from which all the notes of the temperament can be derived). |
 | | In the case of meantone, where the generator can be defined as the meantone approximation of a perfect fourth (4:3), this results in the mapping <1, 2, 4] for the octave and <0, -1, -4] for the fourth. |
 | | Temperaments with 7-limit approximations typically have four elements in their val and monzo vectors, representing the prime factors 2, 3, 5, and 7. |
