pymusicxml.score_components.Part

class pymusicxml.score_components.Part(part_name: str, measures: Optional[Sequence[Measure]] = None, part_id: int = 1, instrument_name: Optional[str] = None, midi_program_num: Optional[int] = None)

Bases: MusicXMLComponent, MusicXMLContainer

Represents a musical part/staff.

Parameters:

• part_name – name of this part

• measures – list of measures contained in this part

• part_id – unique identifier for the part (set automatically by the containing Score upon rendering)

• instrument_name – used by notation programs to understand which sound to use; not rendered in score. Set automatically based on part name if left as None.

• midi_program_num – the general midi program number for the instrument. Again, used by notation programs to pick an instrument sound. Set automatically based on part name if left as None.

property measures: Sequence[Measure]

List of the measures in this Part.

iter_leaves(which_voices=None) → Iterator[Note | Chord | Rest]

Iterates through the Notes/Chords/Rests in this part, expanding out any measures, tuplets and beam groups. The notes/chords/rests are ordered in time, and draw from the specified voices.

Parameters:

which_voices – List of voices to return notes from (numbered 0, 1, 2, 3). The default value of None returns notes from all voices.

iter_directions(direction_type=None) → Iterator[Direction]

Iterates through all directions, or all directions of a certain type, in this Part.

Parameters:

direction_type – the type of direction to filter for, if any

iter_notations(notation_type=None) → Iterator[Notation]

Iterates through all notations, or all notations of a certain type, in this Part.

Parameters:

notation_type – the type of notation to filter for, if any

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 “score-part” tag 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.
