Function Reference
ARGUMENTS:
  - classreps list of PROG-CLASSREP expressions [default = (0 1 2 3 4 5 6 7 8 9 10 11)]
  - from-chord list of integers  
  - weightlist list of numbers [default = (0 4 4 1 1 1 1 1 1 1 4 4)]
&optional
 
  - n modulus of the pc space [default = 12]

Description:


Returns a key function for sorting a list of chords based on a
weighted sum of the positions in the progression vector from
FROM-CHORD to each chord in the list. Progression vectors are
calculated for the intervals represented in CLASSREPS, which
should be a list of PROG-CLASSREP expressions with special
syntax. For more information, see PARSE-PROG-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.
