pymusicxml.score_components.BeamedGroup

class pymusicxml.score_components.BeamedGroup(contents: Optional[Sequence[MusicXMLComponent]] = None)

Bases: DurationalObject, MusicXMLContainer

Represents a group of notes/chords/rests joined under a single beam.

Parameters:

contents – a list of notes, chords and rests contained in this group.

Methods

min_denominator()	Minimum divisor of a quarter note that would be needed to represent the duration of this note accurately.
render()	Renders this component to a tuple of ElementTree.Element.
render_contents_beaming()	Works out all the beaming for the contents of this group.
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

divisions	Subdivision used when representing this duration.
length_in_divisions	Length in terms of subdivisions.
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.

render_contents_beaming() → None

Works out all the beaming for the contents of this group. (Sets the “beams” attribute for every element.)

property divisions: int

Subdivision used when representing this duration.

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.

property written_length: float

Written length in terms of the number of quarter notes.

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.

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.)

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.
