pitchtools.InversionEquivalentDiatonicIntervalClassSegment

class abjad.tools.pitchtools.InversionEquivalentDiatonicIntervalClassSegment.InversionEquivalentDiatonicIntervalClassSegment.InversionEquivalentDiatonicIntervalClassSegment(*args, **kwargs)

New in version 2.0.

Abjad model of inversion-equivalent diatonic interval-class segment:

abjad> pitchtools.InversionEquivalentDiatonicIntervalClassSegment([('major', 2), ('major', 9), ('minor', -2), ('minor', -9)])
InversionEquivalentDiatonicIntervalClassSegment(M2, M2, m2, m2)

Inversion-equivalent diatonic interval-class segments are immutable.

InversionEquivalentDiatonicIntervalClassSegment.is_tertian

True when all diatonic interval-classes in segment are tertian. Otherwise false:

abjad> dics = pitchtools.InversionEquivalentDiatonicIntervalClassSegment([('major', 3), ('minor', 6), ('major', 6)])
abjad> dics.is_tertian
True

Return boolean.

Methods

InversionEquivalentDiatonicIntervalClassSegment.count(value) → integer -- return number of occurrences of value

Note

Inherited from __builtin__.tuple

InversionEquivalentDiatonicIntervalClassSegment.index(value[, start[, stop]]) → integer -- return first index of value.

Raises ValueError if the value is not present.
