pitchtools.TwelveToneRow

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

New in version 2.0.

Abjad model of twelve-tone row:

abjad> pitchtools.TwelveToneRow([0, 1, 11, 9, 3, 6, 7, 5, 4, 10, 2, 8])
TwelveToneRow([0, 1, 11, 9, 3, 6, 7, 5, 4, 10, 2, 8])

Twelve-tone rows validate pitch-classes at initialization.

Twelve-tone rows inherit canonical operators from numbered chromatic pitch-class segment.

Twelve-tone rows return numbered chromatic pitch-class segments on calls to getslice.

Twelve-tone rows are immutable.

Read-only Properties

TwelveToneRow.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.

Note

Inherited from pitchtools.NumberedChromaticPitchClassSegment

TwelveToneRow.numbered_chromatic_pitch_class_set

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.

Inherited from pitchtools.NumberedChromaticPitchClassSegment

Methods

TwelveToneRow.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.

Note

Inherited from pitchtools.NumberedChromaticPitchClassSegment

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

Note

Inherited from __builtin__.tuple

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

Raises ValueError if the value is not present.

Note

Inherited from __builtin__.tuple

TwelveToneRow.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.

Note

Inherited from pitchtools.NumberedChromaticPitchClassSegment

TwelveToneRow.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)

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.

Note
