LilyPond notation

Originally proposed at Wikidata:Property proposal/Creative work

   Done: no label (P5482) (Talk and documentation)

Description	musical notation in LilyPond syntax
Represents	LilyPond (Q195946)
Data type	String
Domain	items related in some way to music (Q638)
Allowed values	LilyPond is too complicated for a regex-based constraint
Example 1	C major scale (Q20640627) → \relative c' {c d e f g a b c}
Example 2	(C melodic minor scale) → \relative c' {c d ees f g a b c | c bes aes g f ees d c} (could be split as below w/ascending and descending scales)
Example 3	Hindol (Q46425) → \relative c' {c e fis a b a c} (applies to part (P518) Arohana (Q2011823))
Example 4	Hindol (Q46425) → \relative c' {c' b a fis e c} (applies to part (P518) avarohana (Q13583589))
Example 5	Hindol (Q46425) → \relative c' {c e fis a b a fis e c} (applies to part (P518) pakad (Q7125406))
Example 6	Tintal (Q2541238) → \drums {cb hh hh cb cb hh hh cb cb hc hc sn sn hh hh cb} (subject to change)

Motivation

Per Mahir256's comments on Wikidata:Project chat#Proposal for a musical notation datatype for properties; see phab:T198233 (basically, Parsons code (P1236) is too limiting for most musical scales and many simple musical works). This would ideally require the creation of a new data type which renders values using the Score extension, and this would probably be the sort of mechanism for finding constraint errors.

Discussion

• @Jc86035: Please provide an example David (talk) 09:26, 30 June 2018 (UTC)

  @ديفيد عادل وهبة خليل 2: I've added one. Mahir256 provided some other examples in the linked discussion but I don't know how they would be structured. Jc86035 (talk) 14:31, 30 June 2018 (UTC)

•  Comment Support Although I was proposing an entire datatype, not a specific property, for musical notation purposes., I won't oppose this proposed property, however, if its creation leads to the future creation of specific properties for specific types of snippets. Mahir256 (talk) 22:09, 1 July 2018 (UTC)

  @Mahir256: I'm aware of that, but it seemed to me that it would take much longer to create the datatype because it would require a technical change, whereas properties can be created out of thin air with consensus. Jc86035 (talk) 07:13, 2 July 2018 (UTC)

  @Mahir256: Would it be fine to have a time signature and bar lines for scales? I can't figure out how to turn them off. Jc86035 (talk) 03:16, 3 July 2018 (UTC)

  @Jc86035: I don't think it matters; the point is to show each of the scale degrees on a staff in either ascending or descending order, so as long as that's done any time signature or bar lines should be okay. Mahir256 (talk) 03:21, 3 July 2018 (UTC)

  @Jc86035: For future reference, \omit Score.BarLine will remove all barlines and \omit Staff.TimeSignature will remove the time signatures. Ebe123 (talk | contributions) 22:03, 19 July 2018 (UTC)

•  Support I think this is reasonable, given the constraint on length and the potential for a future datatype supporting it it would probably be useful to have some examples ready to use. ArthurPSmith (talk) 17:28, 2 July 2018 (UTC)

@ديفيد عادل وهبة خليل 2, ArthurPSmith, Jc86035, Mahir256:  Done: P5482 (P5482). − Pintoch (talk) 07:56, 19 July 2018 (UTC)

Little clarification needed: This property would only include the musical notation information, assuming <score raw=False> (a default LY template to add music inside), and not requiring a full LY file to be constructed manually (which would increase the length a bit).

@Ebe123: Could you add this as a Wikidata usage instructions (P2559) statement at Property:P5482? I'm not sure how this would be phrased so I haven't added it myself. Jc86035 (talk) 13:04, 20 July 2018 (UTC)
