ScaleDegreeMixinForNote
class definition
[abstract class] ScaleDegreeMixinForNote extends the pitch representation of the class Note (HS.score.note). Whereas Note provides a pitch class representation, ScaleDegreeMixinForNote extends this Note class by support for scale degrees. This mixin defines the two parameters scaleDegree and scaleAccidental. scaleDegree denotes the degree of the note's pitch in the scale the note is related to. scaleAccidental denotes an accidental for scaleDegree in that scale, encoded as described in the doc for DegreeToPC. The relation between pitchClass, scaleDegree and scaleAccidental is constrained.
ScaleDegreeMixinForNote is defined as a mixin to make it more easy to combine this mixin with other extensions to the class Note. ScaleDegreeMixinForNote is designed to extend the class Note, because this mixin depends on the note mixin InScaleMixinForNote (HS.score.inScaleMixinForNote).
NB: Scale accidentals can be large: in case of non-diatonic tones (InScaleB=0), the neares diatonic tones can be several semitones away (or whatever the setting of PitchesPerOctave is). Therefore, set AccidentalOffset sufficiently high.
NB: the parameters scaleDegree and scaleAccidental are only constrained in their relation to the parameter pitchClass _after_ the related scale is known and fully determined.
