pymusicxml.score_components.PartGroup

class pymusicxml.score_components.PartGroup(parts: Optional[Sequence[Part]] = None, has_bracket: bool = True, has_group_bar_line: bool = True)

Bases: MusicXMLComponent, MusicXMLContainer

Represents a part group (a group of related parts, possible connected by a bracket)

Parameters:

• parts – list of parts contained in this group

• has_bracket – whether or not to place a bracket around the group in the score

• has_group_bar_line – whether or not to have bar lines cut through the entire group

Methods

render()	Renders this component to a tuple of ElementTree.Element.
render_part_list_entry()	Renders the "part-group" tag and containing "score-part" tags for the top of the MusicXML score.
wrap_as_score()	Wraps this component in a Score so that it can be exported and viewed

Inherited Methods

append(value)	S.append(value) -- append value to the end of the sequence
clear()
count(value)
export_to_file(file_path[, pretty_print])	Exports this musical object (wrapped as a score) to the given file path.
extend(values)	S.extend(iterable) -- extend sequence by appending elements from the iterable
index(value, [start, [stop]])	Raises ValueError if the value is not present.
insert(i, o)	Insert the given object before the given index.
pop([index])	Raise IndexError if list is empty or index is out of range.
remove(value)	S.remove(value) -- remove first occurrence of value.
reverse()	S.reverse() -- reverse IN PLACE
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.

Attributes

parts

List of parts in this group.

property parts: Sequence[Part]

List of parts in this group.

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.)

render_part_list_entry() → Sequence[Element]

Renders the “part-group” tag and containing “score-part” tags for the top of the MusicXML score.

wrap_as_score() → Score

Wraps this component in a Score so that it can be exported and viewed

append(value)

S.append(value) – append value to the end of the sequence

clear() → None -- remove all items from S

count(value) → integer -- return number of occurrences of value

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

extend(values)

S.extend(iterable) – extend sequence by appending elements from the iterable

index(value[, start[, stop]]) → integer -- return first index of value.

Raises ValueError if the value is not present.

Supporting start and stop arguments is optional, but recommended.

insert(i, o) → None

Insert the given object before the given index.

Parameters:

• i – Index at which to insert

• o – Object to insert

pop([index]) → item -- remove and return item at index (default last).

Raise IndexError if list is empty or index is out of range.

remove(value)

S.remove(value) – remove first occurrence of value. Raise ValueError if the value is not present.

reverse()

S.reverse() – reverse IN PLACE

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

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.
