This system is suitable for temperaments with consonant intervals far away in the [[chain of fifths]], such as [[schismatic]]. More naturals is usually unnecessary, since the [[12-comma]] is much smaller than the [[256/243|limma]] in JI. For the meantone chromatic scale [[7L 5s]], there are two approches to use this system, in anology to using the standard notation system for the [[2L 5s|antidiatonic]] scale. | ||
