pitchtools.NumberedChromaticPitchClassSegment

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

New in version 2.0.

Abjad model of a numbered chromatic pitch-class segment:

abjad> pitchtools.NumberedChromaticPitchClassSegment([-2, -1.5, 6, 7, -1.5, 7])
NumberedChromaticPitchClassSegment([10, 10.5, 6, 7, 10.5, 7])

Numbered chromatic pitch-class segments are immutable.

Read-only Properties

NumberedChromaticPitchClassSegment.inversion_equivalent_chromatic_interval_class_segment

Read-only inversion-equivalent chromatic interval-class segment:

numbered_chromatic_pitch_class_segment = pitchtools.NumberedChromaticPitchClassSegment([10, 10.5, 6, 7, 10.5, 7])
numbered_chromatic_pitch_class_segment.inversion_equivalent_chromatic_interval_class_segment
InversionEquivalentChromaticIntervalClassSegment(0.5, 4.5, 1, 3.5, 3.5)

Return inversion-equivalent chromatic interval-class segment.

NumberedChromaticPitchClassSegment.numbered_chromatic_pitch_class_set

Read-only numbered chromatic pitch-class set from numbered chromatic pitch-class segment:

numbered_chromatic_pitch_class_segment = pitchtools.NumberedChromaticPitchClassSegment([10, 10.5, 6, 7, 10.5, 7])
numbered_chromatic_pitch_class_segment.numbered_chromatic_pitch_class_set
NumberedChromaticPitchClassSet([6, 7, 10, 10.5])

Return numbered chromatic pitch-class set.

Methods

NumberedChromaticPitchClassSegment.alpha()

Morris alpha transform of numbered chromatic pitch-class segment:

numbered_chromatic_pitch_class_segment = pitchtools.NumberedChromaticPitchClassSegment([10, 10.5, 6, 7, 10.5, 7])
numbered_chromatic_pitch_class_segment.alpha()
NumberedChromaticPitchClassSegment([11, 11.5, 7, 6, 11.5, 6])

Return numbered chromatic pitch-class segment.

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

Note

Inherited from __builtin__.tuple

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

Raises ValueError if the value is not present.

Note

Inherited from __builtin__.tuple

NumberedChromaticPitchClassSegment.invert()

Invert numbered chromatic pitch-class segment:

numbered_chromatic_pitch_class_segment = pitchtools.NumberedChromaticPitchClassSegment([10, 10.5, 6, 7, 10.5, 7])
numbered_chromatic_pitch_class_segment.invert()
NumberedChromaticPitchClassSegment([2, 1.5, 6, 5, 1.5, 5])

Return numbered chromatic pitch-class segment.

NumberedChromaticPitchClassSegment.multiply(n)

Multiply numbered chromatic pitch-class segment by n:

numbered_chromatic_pitch_class_segment = pitchtools.NumberedChromaticPitchClassSegment([10, 10.5, 6, 7, 10.5, 7])
numbered_chromatic_pitch_class_segment.multiply(5)
NumberedChromaticPitchClassSegment([2, 4.5, 6, 11, 4.5, 11])

Return numbered chromatic pitch-class segment.

NumberedChromaticPitchClassSegment.retrograde()

numbered_chromatic_pitch_class_segment = pitchtools.NumberedChromaticPitchClassSegment([10, 10.5, 6, 7, 10.5, 7])
numbered_chromatic_pitch_class_segment.retrograde()
NumberedChromaticPitchClassSegment([7, 10.5, 7, 6, 10.5, 10])

Return numbered chromatic pitch-class segment.

NumberedChromaticPitchClassSegment.rotate(n)

Rotate numbered chromatic pitch-class segment:

numbered_chromatic_pitch_class_segment = pitchtools.NumberedChromaticPitchClassSegment([10, 10.5, 6, 7, 10.5, 7])
numbered_chromatic_pitch_class_segment.rotate(1)
NumberedChromaticPitchClassSegment([7, 10, 10.5, 6, 7, 10.5])

Return numbered chromatic pitch-class segment.

NumberedChromaticPitchClassSegment.transpose(n)
