Reference records

[craigsapp]

In the header (005.krn as an example):

!!!COM: Fux, Johann Joseph
!!!OMD: Gradus ad Parnassum Exercise
!!!YEC: CC0 1.0 Universal (Public Domain). Mark Gotham and FourScoreAndMore.org waive all rights to this document

Stylistically, I put YEC at the bottom: it is bureaucratic text that does not contain basic work information. (but it is OK to otherwise put it at the top for a local styling).

OMD is problemmatic: I would rather use OPR ("Opus PaRent"), describing the common title of the larger work. Nearly equivalent it GTL (Group TitLe).

From the page: https://www.humdrum.org/reference-records/index.html

I think OTL is the composer naming the group, while GTL is more proleptic.

Your actual title is embedded in a strange way:

*clefG2 *clefG2
*k[]    *k[]
!!LO:TX:omd:t=
*M2/2   *M2/2
=1      =1
!       !LO:TX:a:t=Fig. 5; Species: 1; Modal final: d; Cantus firmus: Lower
1d      1a
=2      =2
1f      1a

Obviously !!LO:TX:omd:t= was used to suppress !!!OMD instead the would be:

!!!OMD: Fig. 5; Species: 1; Modal final: d; Cantus firmus: Lower

I would instead call this a title:

!!!OTL: Fig. 5; Species: 1; Modal final: d; Cantus firmus: Lower

A problem is that you are embedding multiple references into a single reference, better:

!!!OTL: Fig. 5; Species: 1; Modal final: d; Cantus firmus: Lower
!!!species: 1
!!!final: d
!!!cantfirm: Lower

If you want to avoid a title but still view in the header section of the title:

!!!title: Fig. 5; Species: @{species} Modal final: @{final); Cantus firmus: @{cantfirm}
!!!species: 1
!!!final: d
!!!cantfirm: Lower

Thanks for these notes on krn style.

These files are automatic conversions.

Should I be using your converted instead of converter21? Would that improve these matters?

Not much. Compressed mxl in theory can be dragged/dropped, but for some reason (based on file name?) it is not working.

Not too much difference. Line 12 is still problemmatic: the problem is the data and not the conversion (no concept of attaching text to a system rather than a staff).

Line 37:

 !!!system-decoration: s1,s2

Is not optimal, but correct (single line between staves, rather than a more standard bracket:

converter 21 does not give a system decoration line, so by default it assumes piano staff and gives a brace:

(So better in my converter)

Other interesting differences is line 30:

!!linebreak:original

my converter preserves the line breaks. This short piece it is unimportant, but in longer works it is more interesting for further proofrearing.

Also the !!!COM (Coposer) is the last line in my converter. I would generally put it as the top reference record, so I should fix that.

The C# in m.10, MusicXML:

      <note default-x="62.15" default-y="-15">
        <pitch>
          <step>C</step>
          <alter>1</alter>
          <octave>5</octave>
          </pitch>
        <duration>4</duration>
        <voice>1</voice>
        <type>whole</type>
        <accidental>sharp</accidental>
        </note>

It is correct/best to convert to:

1c#X

The # comes from <alter>1</alter> (sounding C-sharp), and the X comes from <accidental>sharp</accidental> (written C-sharp).

This should be OK for all transpositions, if doin a modal transpositions, you would need to remove the 'X's.
