pymusicxml.score_components.Clef

class pymusicxml.score_components.Clef(sign: str, line: int, octaves_transposition: int = 0)[source]

Bases: pymusicxml.score_components.MusicXMLComponent

Class representing a musical clef

Parameters
  • sign – Whether it is a G, F, or C clef

  • line – Which line the clef is centered on

  • octaves_transposition – How many octaves up or down the clef transposes

Methods

from_string(clef_string[, octaves_transposition])

Constructs a clef from one of the standard names, e.g.

render()

Renders this component to a tuple of ElementTree.Element.

wrap_as_score()

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

Inherited Methods

export_to_file(file_path[, pretty_print])

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

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

clef_name_to_letter_and_line

Dictionary mapping standard clef names to tuple of (clef letter type, clef line)

clef_name_to_letter_and_line = {'alto': ('C', 3), 'baritone': ('F', 3), 'bass': ('F', 4), 'mezzo-soprano': ('C', 2), 'soprano': ('C', 1), 'tenor': ('C', 4), 'treble': ('G', 2)}

classmethod from_string(clef_string: str, octaves_transposition: int = 0)[source]

Constructs a clef from one of the standard names, e.g. treble, bass, alto

Parameters
  • clef_string – name of the clef

  • octaves_transposition – octaves of transposition up or down to be applied to the clef

render() → Sequence[xml.etree.ElementTree.Element][source]

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()pymusicxml.score_components.Score[source]

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

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

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.
