{{main|Musical parameter}}
In music theory, a parameter denotes an element which may be manipulated (composed), separately from the other elements. The term is used particularly for [[pitch (music)|pitch]], [[loudness]], [[duration (music)|duration]], and [[timbre]], though theorists or composers have sometimes considered other musical aspects as parameters. The term is particularly used in [[serial music]], where each parameter may follow some specified series. [[Paul Lansky]] and [[George Perle]] criticized the extension of the word "parameter" to this sense, since it is not closely related to its mathematical sense,<ref>{{Cite Grove |last=Lansky |first=Paul |last2=Perle |first2=George |title=Parameter|name-list-style=amp}}</ref> but it remains common.  The term is also common in music production, as the functions of audio processing units (such as the attack, release, ratio, threshold, and other variables on a compressor) are defined by parameters specific to the type of unit (compressor, equalizer, delay, etc.).
