pymusicxml.score_components.GraceNote

class pymusicxml.score_components.GraceNote(pitch: Pitch | str, duration: Duration | str | float, ties: Optional[str] = None, notations=(), articulations=(), notehead: Optional[Union[Notehead, str]] = None, directions: Sequence[Direction] = (), stemless: bool = False, slashed=False, velocity: Optional[int] = None)[source]

Bases: Note

Subclass of Note representing a durationless grace note.

Parameters:

pitch – see Note
duration – see Note. This will be the displayed duration of the note, even though it takes up no metric space in the bar.
ties – see Note
notations – see Note
articulations – see Note
notations – see Note
articulations – see Note
notehead – see Note
directions – see Note
stemless – see Note
slashed – whether or not this grace note is rendered with a slash.
velocity – a note velocity (0-127) which gets passed along and used for playback by many applications

Inherited Methods

`export_to_file`(file_path[, pretty_print])	Exports this musical object (wrapped as a score) to the given file path.
`min_denominator`()	Minimum divisor of a quarter note that would be needed to represent the duration of this note accurately.
`num_beams`()	Returns the number of beams needed to represent this note's duration.
`render`()	Renders this component to a tuple of ElementTree.Element.
`to_xml`([pretty_print])	Renders this component to MusicXML, adding a version tag, but not wrapping it up as a full score.
`view_in_software`(command)	Uses the given terminal command to create a score out of this musical object, and open it in music notation software.
`wrap_as_score`()	Wraps this component in a `Score` so that it can be exported and viewed

Attributes

`divisions`	Subdivision used when representing this duration.
`length_in_divisions`	Length in terms of subdivisions.
`starts_tie`	Whether or not this note starts a tie.
`stops_tie`	Whether or not this note ends a tie.
`true_length`	True length in terms of the number of quarter notes, taking into tuplet time modification.
`written_length`	Written length in terms of the number of quarter notes.

property divisions: int: Subdivision used when representing this duration.

export_to_file(file_path: str, pretty_print: bool = True) → None

Exports this musical object (wrapped as a score) to the given file path.

Parameters:

file_path – The path of the file we want to write to.
pretty_print – If True, breaks the MusicXML onto multiple lines, with indentation

property length_in_divisions: int: Length in terms of subdivisions. (See description of “divisions” attribute in Duration)

min_denominator() → int: Minimum divisor of a quarter note that would be needed to represent the duration of this note accurately. For instance, a triplet quarter note would have min_denominator 3, since it is 2/3 of a quarter.

num_beams() → int: Returns the number of beams needed to represent this note’s duration.

render() → Sequence[Element]: Renders this component to a tuple of ElementTree.Element. (The reason for making it a tuple is that musical objects like chords are represented by several notes side by side, with all but the first containing a </chord> tag.)

property starts_tie: Whether or not this note starts a tie.

property stops_tie: Whether or not this note ends a tie.

to_xml(pretty_print: bool = False) → str

Renders this component to MusicXML, adding a version tag, but not wrapping it up as a full score.

Parameters:: pretty_print – If True, breaks the MusicXML onto multiple lines, with indentation

property true_length: float: True length in terms of the number of quarter notes, taking into tuplet time modification. Returns 0 in the case of grace notes.

view_in_software(command: str) → None

Uses the given terminal command to create a score out of this musical object, and open it in music notation software.

Parameters:: command – The terminal command corresponding to the software with which we want to open the score.

wrap_as_score() → Score: Wraps this component in a Score so that it can be exported and viewed

property written_length: float: Written length in terms of the number of quarter notes.
