A [[canonical_form|canonical mapping form]] is an important standard to have as a community for uniquely identifying [[temperaments]], but it is not the only mapping form one should ever need, because one may wish to use differently-sized [[generators]] (to ultimately generate the same tempered intervals). Several such forms with different generator sizes have been presented, such as [[Normal_lists#Positive_generator_form|positive generator form]], [[Normal_lists#Equave-reduced_generator_form|equave-reduced generator form]], and [[Normal_lists#Minimal_generator_form|minimal-generator form]]. | A [[canonical_form|canonical mapping form]] is an important standard to have as a community for uniquely identifying [[temperaments]], but it is not the only mapping form one should ever need, because one may wish to use differently-sized [[generators]] (to ultimately generate the same tempered intervals).
