'''Badness''' is a measure that allows the comparative evaluation of tunings, temperaments, interval approximations, etc. in terms of both [[complexity]] and [[error]], two measures that usually vary in opposite directions. | '''Badness''' is a measure that allows the comparative evaluation of tunings, temperaments, interval approximations, etc. in terms of both [[complexity]] and [[error]], two measures that usually vary in opposite directions. | ||
Complexity and error are both usually treated as undesirable characteristics, but there is a trade-off between them in that very low complexity temperaments (e.g. small [[edo]]s) typically do not have low error, and very low error temperaments (e.g. [[microtemperament]]s) typically do not have low complexity. Badness is a way to combine complexity and error such that a search for low-badness temperaments yields results with a particularly good trade-off between complexity and error. | Complexity and error are both usually treated as undesirable characteristics, but there is a trade-off between them in that very low complexity temperaments (e.g. small [[edo]]s) typically do not have low error, and very low error temperaments (e.g. [[microtemperament]]s) typically do not have low complexity.

Several different badness measures are in use, including [[Cangwu badness]], [[TE simple badness]], and [[TE logflat badness]]. | Several different badness measures are in use, including [[Cangwu badness]], [[TE simple badness]], and [[TE logflat badness]]. Some also have several normalizing coefficients. | ||
{{Note| [[Sintel]]'s [[TE logflat badness]] is generally the badness metric used throughout this wiki. Many old pages still use [[Gene Ward Smith|Smith]]'s; those are being phased out. }} | |||
