classmethod from_quantized_performance_part(quantized_performance_part: PerformancePart) → StaffGroup

Constructs a new StaffGroup from an already quantized PerformancePart.

Parameters:

quantized_performance_part – an already quantized PerformancePart

to_music_xml() → PartGroup

Convert this score component to its corresponding pymusicxml component

append(item: ScoreComponent) → None

Add a child ScoreComponent of the appropriate type

export_lilypond(file_path: str, non_score_blocks: Optional[Sequence] = None, **lilypond_file_args) → None

Convert and wrap as a LilyPond (.ly) file, and save to the given path.

Parameters:

• file_path – file path to save to

• non_score_blocks – a list of abjad.Block objects (or strings containing the LilyPond code for such a block, which are then parsed by abjad); typical blocks might be a header block, a layout block, or a paper block. If no header block is specified, one will be created with the score’s title and composer. If a header is specified, title and composer will be added if not present.

• lilypond_file_args – any additional keyword arguments will be passed along to the constructor of abjad.LilyPondFile (assuming wrap_as_file is True). This allows for setting staff size and various other customizations.

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

Convert and wrap as a MusicXML score, and save to the given path.

Parameters:

• file_path – file path to save to

• pretty_print – whether or not to take the extra space and format the file with indentations, etc.

export_pdf(file_path: str, non_score_blocks: Optional[Sequence] = None, **lilypond_file_args) → None

Exports score as a PDF file and saves it to the given file_path

Parameters:

• file_path – where to save the PDF

• non_score_blocks – a list of abjad.Block objects (or strings containing the LilyPond code for such a block, which are then parsed by abjad); typical blocks might be a header block, a layout block, or a paper block. If no header block is specified, one will be created with the score’s title and composer. If a header is specified, title and composer will be added if not present.

• lilypond_file_args – any additional keyword arguments will be passed along to the constructor of abjad.LilyPondFile (assuming wrap_as_file is True). This allows for setting staff size and various other customizations.

extend(items) → None

Add several child ScoreComponents of the appropriate type

index(item) → int

Get the index of the given child ScoreComponent

insert(index, item) → None

Insert a child ScoreComponent at the given index.

pop(i=-1) → ScoreComponent
