Note: In the second column, the ratios 9/5, 11/9, 13/9, and their octave complements are all included here, being 27/15, 33/27, and 39/27 respectively. These ratios are mapped inconsistently to their second-best approximations in the patent val, so despite 9/8 and 10/9 listed in the same row, 21edo is ''not'' a [[meantone]] system. | Note: In the second column, the ratios 9/5, 11/9, 13/9, and their octave complements are all included here, being 27/15, 33/27, and 39/27 respectively.
