music21.editorial

Editorial objects store comments and other metadata associated with specific Music21Object elements such as Notes.

Some of the aspects of Editorial objects represent very early (pre-v0.1) versions of music21. Thus some of the pre-defined aspects might be removed from documentation in the future.

Access an editorial object by calling .editorial on any music21 object:

>>> c = clef.TrebleClef()
>>> ed = c.editorial
>>> ed
<music21.editorial.Editorial {}>

The object is lazily created on first access. To see if there is any existing editorial information without creating the object, call .hasEditorialInformation

>>> n = note.Note('C#4')
>>> n.hasEditorialInformation
False
>>> n.editorial.unedited = True
>>> n.hasEditorialInformation
True

Editorial

class music21.editorial.Editorial

Editorial comments and special effects that can be applied to music21 objects.

>>> ed1 = editorial.Editorial()
>>> ed1.backgroundHighlight = 'yellow'  # non-standard.
>>> ed1.backgroundHighlight
'yellow'
>>> list(ed1.keys())
['backgroundHighlight']
>>> ed1
 <music21.editorial.Editorial {'backgroundHighlight': 'yellow'}>

Every GeneralNote object already has a NoteEditorial object attached to it at object.editorial. Normally you will just change that object instead.

For instance, take the case where a scribe wrote F in the score, knowing that a good singer would automatically sing F-sharp instead. We can store the editorial suggestion to sing F-sharp as a “musica ficta” accidental object:

>>> fictaSharp = pitch.Accidental('sharp')
>>> n = note.Note('F')
>>> n.editorial.ficta = fictaSharp
>>> n.show('lily.png')  # only Lilypond currently supports musica ficta
../_images/noteEditorialFictaSharp.png
