Multiplication

class pitchtools.Multiplication(index=5)

Multiplication operator.

Example 1.

>>> operator_ = pitchtools.Multiplication(index=5)
>>> print(format(operator_))
pitchtools.Multiplication(
    index=5,
    )

Object model of the twelve-tone multiplication operator.

Attribute summary

index Gets index of multiplication.
__call__(expr) Calls tranposition on expr.
__copy__(\*args) Copies Abjad value object.
__eq__(expr) Is true when all initialization values of Abjad value object equal the initialization values of expr.

Read-only properties

Multiplication.index

Gets index of multiplication.

>>> operator_ = pitchtools.Multiplication(index=5)
>>> operator_.index
5

Set to integer or none.

Special methods

Multiplication.__call__(expr)

Calls tranposition on expr.

Example 1. Multiplies numbered pitch-class by 5:

>>> operator_ = pitchtools.Multiplication(index=5)
>>> pc = pitchtools.NumberedPitchClass(4)
>>> operator_(pc)
NumberedPitchClass(8)

Example 2. Multiplies numbered pitch-pitch by 7:

>>> operator_ = pitchtools.Multiplication(index=7)
>>> pitch = pitchtools.NumberedPitchClass(4)
>>> operator_(pitch)
NumberedPitchClass(4)

Returns new object with type equal to that of expr.

(AbjadValueObject).__copy__(*args)

Copies Abjad value object.

Returns new Abjad value object.

(AbjadValueObject).__eq__(expr)

Is true when all initialization values of Abjad value object equal the initialization values of expr.

Returns true or false.

(AbjadObject).__format__(format_specification='')

Formats Abjad object.

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

Returns string.

(AbjadValueObject).__hash__()

Hashes Abjad value object.

Returns integer.

(AbjadObject).__ne__(expr)

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

Returns true or false.

(AbjadObject).__repr__()

Gets interpreter representation of Abjad object.

Returns string.
