signed_interval_class {musicMCT} | R Documentation |
Ordered pitch-class interval represented as interval class with sign
Description
Represents an ordered interval between two pitch-classes as a value between
-edo/2
and edo/2
, i.e. with an absolute value that matches its
interval class as well as a sign (plus or minus) that disambiguates
between the two OPCIs included in the interval-class. That is, C->D is
2
whereas C->B-flat is -2
. Exactly half the octave is represented as a
positive value.
