SetMeasures are methods of analyzing and comparing set-class similarity. Set-class analysis, in dealing with set-classes and not pitch or pitch-class sets, represents a "higher" level of abstraction.
There are a number of different similarity measures available, representing numerous historical approaches to set-class analysis (Castren 1994). To display a complete list of SetMeasures available, enter the command SMls:

As in other displays, the "+" designates the active object. In the above example, "ASIM" is the selected SetMeasure. The selected SetMeasure is used in a number of commands that employ SetMeasures: SCcm, SCs, PScma, and PScmb. In all cases, the active SetMeasure is the analysis method employed.
