Methods

ChordInversion.extent_to_figured_bass_string(extent)

Changes extent to figured bass string.

>>> inversion.extent_to_figured_bass_string(5)
''
>>> inversion.extent_to_figured_bass_string(7)
'7'
>>> inversion = tonalanalysistools.ChordInversion(1)

Special methods

(AbjadValueObject).__copy__(*arguments)

Copies Abjad value object.

Returns new Abjad value object.

ChordInversion.__eq__(argument)

Is true when argument is a chord inversion with number equal to that of this chord inversion. Otherwise false.

>>> inversion_1 = tonalanalysistools.ChordInversion(0)
>>> inversion_2 = tonalanalysistools.ChordInversion(0)
>>> inversion_3 = tonalanalysistools.ChordInversion(1)
>>> inversion_1 == inversion_1
True
>>> inversion_1 == inversion_2
True
>>> inversion_1 == inversion_3
False
>>> inversion_2 == inversion_1
True
>>> inversion_2 == inversion_2
True
>>> inversion_2 == inversion_3
False
>>> inversion_3 == inversion_1
False
>>> inversion_3 == inversion_2
False
>>> inversion_3 == inversion_3
True

Returns true or false.

(AbjadObject).__format__(format_specification='')

Formats Abjad object.

Set format_specification to ‘’ or ‘storage’. Interprets ‘’ equal to ‘storage’.

Returns string.

ChordInversion.__hash__()

Hashes chord inversion.

Required to be explicitly redefined on Python 3 if __eq__ changes.

Returns integer.

(AbjadObject).__ne__(argument)

Is true when Abjad object does not equal argument. Otherwise false.

Returns true or false.

(AbjadObject).__repr__()

Gets interpreter representation of Abjad object.

Returns string.
