[GENERIC-FUNCTION]


OMPitchField
Function Reference
ARGUMENTS:
  - classreps list of INCL-CLASSREP expressions [default = (1 2 3 4 5 6)]
  - refchord list of integers  
&optional
 
  - n modulus of the pc space [default = 12]

Description:


Returns a key function for sorting a list of chords based on the
angle measured from the inclusion vector of REFCHORD to the
inclusion vector of each chord in the list. Inclusion vectors are
calculated for the equivalence classes represented in CLASSREPS,
which should be a list of INCL-CLASSREP expressions with special
syntax. For more information, see PARSE-INCL-CLASSREPS and its
documentation.

The modulus of the pitch class space defaults to 12 but can be set
to other values via the optional parameter N.
