The '''7/11 comma''' is a comma with a ratio of '''45927/45056''' and a value of approximately 33.15 [[cent]]s. | The [[Sagittal]] '''7/11 comma''' is a comma with a [[ratio]] of '''45927/45056''' and a value of approximately 33.15 [[cent]]s. It is the apotome complement of [[22/21]], and the difference between the [[Pythagorean comma]] and the [[896/891|pentacircle comma (896/891)]]. It is the comma that separates [[11/7]] and the [[6561/4096|Pythagorean augmented fifth]], and separates [[14/11]] and the [[8192/6561|Pythagorean diminished fourth]]. | ||
In the Sagittal system, the downward version of this comma (possibly tempered) is represented by the sagittal {{sagittal | (! }} and is called the '''11/7 comma''', or '''11/7C''' for short, because the simplest interval it notates is 11/7, as for example in E{{nbhsp}}{{sagittal | b }}-B{{nbhsp}}{{sagittal | (! }}. The upward version is called '''7/11C''' or '''11/7C up''' and is represented by {{sagittal| (| }}. | |||
