Error is a measurement of the deviation of an interval from another interval that it is approximating. The retronym absolute error is sometimes used to contrast it with relative error.

For example, the tempered ~3/2 of quarter-comma meantone is 696.578¢, while a just 3/2 is 701.955¢, so the error of this ~3/2 is 696.578¢ - 701.955¢ = -5.377¢.

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