Tremolo

class indicatortools.Tremolo(beam_count=3, is_slurred=None)

Tremolo (of exactly two notes).

>>> import abjad

With two beams:

>>> chord = abjad.Chord("<cs' e'>4")
>>> tremolo = abjad.Tremolo(beam_count=2)
>>> abjad.attach(tremolo, chord)
>>> show(chord) 

With three beams:

>>> chord = abjad.Chord("<cs' e'>4")
>>> tremolo = abjad.Tremolo(beam_count=3)
>>> abjad.attach(tremolo, chord)
>>> show(chord) 

Tremolo affects the formatting of chords.

Tremolo has no effect when attached to notes or rests.

Read-only properties

Tremolo.beam_count

Gets beam count of tremolo.

With two beams:

>>> chord = abjad.Chord("<cs' e'>4")
>>> tremolo = abjad.Tremolo(beam_count=2)
>>> abjad.attach(tremolo, chord)
>>> show(chord) 

With three beams:

>>> chord = abjad.Chord("<cs' e'>4")
>>> tremolo = abjad.Tremolo()
>>> abjad.attach(tremolo, chord)
>>> show(chord) 

Set to positive integer.

Defaults to 3.

Returns positive integer.

Tremolo.is_slurred

Is true when tremolo is slurred. Otherwise false.

Without slur:

>>> chord = abjad.Chord("<cs' e'>4")
>>> tremolo = abjad.Tremolo()
>>> abjad.attach(tremolo, chord)
>>> show(chord) 

With slur:

>>> chord = abjad.Chord("<cs' e'>4")
>>> tremolo = abjad.Tremolo(is_slurred=True)
>>> abjad.attach(tremolo, chord)
>>> show(chord) 

Set to true or false.

Defaults to false.

Returns true or false.

Special methods

Tremolo.__copy__(*arguments)

Copies tremolo.

Copies tremolo:

>>> import copy
>>> tremolo_1 = abjad.Tremolo(beam_count=2)
>>> tremolo_2 = copy.copy(tremolo_1)
>>> tremolo_1 == tremolo_2
True
>>> tremolo_1 is not tremolo_2
True

Returns new tremolo.

(AbjadValueObject).__eq__(argument)

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

Returns true or false.

Tremolo.__format__(format_specification='')

Formats stem tremolo.

With two beams:

>>> tremolo = abjad.Tremolo(beam_count=2)
>>> print(format(tremolo))
abjad.Tremolo(
    beam_count=2,
    )

With three beams:

>>> tremolo = abjad.Tremolo(beam_count=3)
>>> print(format(tremolo))
abjad.Tremolo(
    beam_count=3,
    )

Returns string.

(AbjadValueObject).__hash__()

Hashes Abjad value object.

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.

Tremolo.__str__()

Gets string representation of tremolo.

With two beams:

>>> tremolo = abjad.Tremolo(beam_count=2)
>>> str(tremolo)
'Tremolo(beam_count=2)'

With three beams:

>>> tremolo = abjad.Tremolo(beam_count=3)
>>> str(tremolo)
'Tremolo(beam_count=3)'

Returns string.
