pymusicxml.score_components.Transpose

class pymusicxml.score_components.Transpose(chromatic: int, diatonic: Optional[int] = None, octave: Optional[int] = None)

Bases: MusicXMLComponent

Class representing transposition. Used for instruments like guitar or bass which transpose by an octave down.

The <transpose> element represents what must be added to a written pitch to get a correct sounding pitch. It is used for encoding parts for transposing instruments that are in written vs. concert pitch.

Parameters:

• chromatic – Chromatic transposition

• diatonic – Diatonic transposition (optional)

• octave – Octave change (optional)

Methods

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.

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

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.
