**semits), pitch-class (**pc),
normal form (**nf), prime form (**pf),
or Fortean set name (**pcset).
An interval-class vector is a six-element numerical list that indicates
the abundance of various interval-classes (from 1 semitone
to 6 semitones) for some pitch-class set.
See
REFERENCES below.
When provided with **semits or **pc inputs,
iv
treats each input record as a set of pitches.
Unisons and other pitch-class duplications have no effect on the output.
Rests within a set of pitches are ignored;
where an input record consists solely of one or more
rests, a null-token is output.
The
iv
command is able to translate any of the representations listed below.
For descriptions of the various input representations
(including **iv) refer to Section 2
(Representation Reference)
of this reference manual.
It is recommended that output files produced using the iv command should be given names with the distinguishing `.iv' extension.
