Humdrum wiki extension

The CCARH wiki includes a Humdrum music notation extension that allows Humdrum data embedded within a page to be rendered as graphical music notation.

Here is a basic example:

<humdrum>

• • kern

1f;

• -

</humdrum>

The above notation was created with the text:

  <humdrum>
  **kern
  1f;
  *-
  </humdrum>

Here is a more complicated example that includes lyrics, coloring of notes with RDF records, and a transposition filter (Transposing from A-flat major in the data to C major in the notation).

<humdrum scale="55"> !!!OMD: Slow

• • kern **text
• k[b-e-a-d-] *
• A-: *
• M4/4 *
• met(c) *
• *color:gold

4cc If =1 =1 (8dd-L@ Mu- 8ccJ)@ . (8b-L@ -sic_ 8a-J)@ . (8gL be_ 8a-J) . (8b-L the_ 8ccJ) . =2 =2 (8b-L food_ 8a-J) . (8gL of_ 8fJ) . 4.enN Love, 8c sing =3 =3 4f on, 4f sing 4.a- on, 8f sing =4 =4 4cc on, 4cc sing 4.ee- on, =- =-

• - *-

!!!RDF**kern: @ = marked note, color=chartreuse !!!RDF**kern: N = marked note, color=hotpink !!!filter: transpose -k c </humdrum>

which was created with the text:

  <humdrum scale="55">
  !!!OMD: Slow
  **kern	**text
  *k[b-e-a-d-]	*
  *A-:	*
  *M4/4	*
  *met(c)	*
  4cc	If
  =1	=1
  (8dd-L@	Mu-
  8ccJ)@	.
  (8b-L@	-sic_
  8a-J)@	.
  (8gL	be_
  8a-J)	.
  (8b-L	the_
  8ccJ)	.
  =2	=2
  (8b-L	food_
  8a-J)	.
  (8gL	of_
  8fJ)	.
  4.enN	Love,
  8c	sing
  =3	=3
  4f	on,
  4f	sing
  4.a-	on,
  8f	sing
  =4	=4
  4cc	on,
  4cc	sing
  4.ee-	on,
  =-	=-
  *-	*-
  !!!RDF**kern: @ = marked note, color=chartreuse
  !!!RDF**kern: N = marked note, color=hotpink
  !!!filter: transpose -k c
  </humdrum>

The standard wikimedia page editor does not allow inserting tab characters, so either copy-and-paste humdrum text from another editor, such as http://verovio.humdrum.org, or encode the Humdrum data in CSV format instead of TSV:

  <humdrum scale="55">
  !!!OMD: Slow
  **kern,**text
  *k[b-e-a-d-],*
  *A-:,*
  *M4/4,*
  *met(c),*
  4cc,If
  =1,=1
  (8dd-L@,Mu-
  8ccJ)@,.
  (8b-L@,-sic_
  8a-J)@,.
  (8gL,be_
  8a-J),.
  (8b-L,the_
  8ccJ),.
  =2,=2
  (8b-L,food_
  8a-J),.
  (8gL,of_
  8fJ),.
  4.enN,"Love,"
  8c,sing
  =3,=3
  4f,"on,"
  4f,sing
  4.a-,"on,"
  8f,sing
  =4,=4
  4cc,"on,"
  4cc,sing
  4.ee-,"on,"
  =-,=-
  *-,*-
  !!!RDF**kern: @ = marked note, color=chartreuse
  !!!RDF**kern: N = marked note, color=hotpink
  !!!filter: transpose -k c
  </humdrum>
  

The TSV form of Humdrum can be converted to CSV on VHV by using the alt-u command.

Options

The Humdrum notation extension is implemented using the humdrum javascript plugin documented at https://plugin.humdrum.org. All of the options described in that documentation can be used as attributes for the humdrum element on a wiki page. The full list of options: https://plugin/humdrum.org/options.

Here is an example that loads the Humdrum data from an external source, and it is not stored in the webpage:

<humdrum

        url="https://raw.githubusercontent.com/craigsapp/mozart-piano-sonatas/master/kern/sonata06-3c.krn"
        scale="33"
        header="true"

></humdrum>

This musical example was created with the following text:

  <humdrum 
           url="https://raw.githubusercontent.com/craigsapp/mozart-piano-sonatas/master/kern/sonata06-3c.krn"
           scale="33"
           header="true"
  ></humdrum>

In this case, the music is downloaded from the Github repository https://github.com/craigsapp/moart-piano-sonatas.
