-The [[5-limit]] interval '''135/128''', about 92.2 [[cent]]s in size, is called the '''pelogic comma''', '''major limma''' or '''major chroma'''. It is a [[syntonic comma]] away from the pythagorean major semitone [[2187/2048]], and so is tuned justly in 1/7 comma meantone. Flattening by another syntonic comma reaches the even simpler [[25/24]].
