 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 7limit approximations typically have four elements in their val and monzo vectors, representing the prime factors 2, 3, 5, and 7.
