'''Error''' is a measurement of the deviation of an [[interval]] from another interval that it is approximating. The {{w|retronym}} ''absolute error'' is sometimes used to contrast it with [[relative error]].

'''Error''' is a measurement of the deviation of an [[interval]] from another interval that it is approximating. The {{w|retronym}} ''absolute error'' is sometimes used to contrast it with [[relative error]]. Error is usually signed, with a positive value indicating an overshoot of the target, and a negative value indicating an undershoot.

For example, the [[regular temperament|tempered]] ~3/2 of [[quarter-comma meantone]] is 696.578¢, while a [[JI|just]] 3/2 is 701.955¢, so the error of this ~3/2 is {{nowrap|696.578¢ ~~−~~ 701.955¢ {{=}} ~~−5~~.377¢}}.

For example, the [[regular temperament|tempered]] ~3/2 of [[quarter-comma meantone]] is 696.578¢, while a [[JI|just]] 3/2 is 701.955¢, so the error of this ~3/2 is {{nowrap|696.578¢ − 701.955¢ {{=}} −5.377¢}}.

In [[Paul Erlich]]'s Middle Path paper, error is called ''mistuning''.
