Original Wikitext content:

1/6 comma meantone is the tuning of [[Meantone family|meantone temperament]] which tunes the fifth as the sixth root of 45/4, or in other words 698.371 cents. This means the fifth is flattened by 1/6 of the syntonic comma (81/80 ratio) of 21.506 cents, which is to say by 3.584 cents, hence the name 1/6-comma meantone. It is closely related to [[55edo]] in terms of its tuning.

=Fractional projection matrix=
The [[Fractional monzos|fractional projection map]] defining 7-limit 1/6 comma meantone is

|| [2/3 1/3 1/6 0> ||
|| [-4/3 4/3 2/3 0> ||
