The '''forge comma''' is the [[7-limit]] [[unnoticeable comma]] '''1640558367/1638400000''', which measures roughly 2.28 [[cent]]s. It's notable as the interval separating the [[amity comma]] from the [[gamelisma]]. This comma was first found as the 7-limit comma linking [[12edo]], [[34edo]] and [[159edo]]. The various 11-limit families that temper out this comma are named after various metal objects made in a forge, hence '''[[the Forge]]''' as the name of this collection of temperaments. | The '''forge comma''' is the [[7-limit]] [[unnoticeable comma]] '''1640558367/1638400000''', which measures roughly 2.28 [[cent]]s.
