pymusicxml.spanners.StartBracket

class pymusicxml.spanners.StartBracket(label: Any = 1, line_type: str | LineType = 'dashed', line_end: Optional[Union[str, LineEnd]] = None, end_length: Optional[Real] = None, text: Optional[Union[str, TextAnnotation]] = None, placement: str | StaffPlacement = 'above', voice: int = 1, staff: Optional[int] = None)[source]

Bases: Direction, StartNumberedSpanner

Start of a bracket spanner.

Parameters:

  • label – each spanner is given an label to distinguish it from other spanners of the same type. In the MusicXML standard, this is a number from 1 to 6, but in pymusicxml it is allowed to be anything (including, for instance, a string). These labels are then converted to numbers on export.

  • line_end – Type of hook/arrow at the start of this bracket

  • end_length – Length of the hock at the start of this bracket

  • text – Any text to attach to the start of this bracket

  • placement – Where to place the direction in relation to the staff (“above” or “below”)

  • voice – Which voice to attach to

  • staff – Which staff to attach to if the part has multiple staves

Methods

render()

Renders this component to a tuple of ElementTree.Element.

render_direction_type()

Renders the <direction-type> element that constitutes the main substance of a <direction> element.

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.

wrap_as_score()

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

Attributes

STOP_TYPE

alias of StopBracket

render_direction_type() → Sequence[Element][source]

Renders the <direction-type> element that constitutes the main substance of a <direction> element.

render() → Sequence[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.)

MID_TYPES: Sequence[MidNumberedSpanner] = ()
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.

wrap_as_score() → Score

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