3.7 Evolution - Early Music

• Oct 4, 2024 - 15:34

Ben Byram-Wigfield (aka benwiggy) created a SMuFL font "Valerio" for notating early music. (SIL Open Font License)
See Dorico forum:

This font can be used in 3.7 Evolution
Edit: New screenshot after fix by Jojo.

Remember to rename (copy) Valerio.json to metadata.json.

Hmm, maybe not: looking at, for example, a quarter note, in the metadata there is no noteQuarterDown (down stem), just a noteQuarterUp, so there may be stuff missing?
OTOH: changing it's bBoxSW and bBoxNe doesn't seem to have any effect, neither has changing noteheadBlack (which might be the one used here for quarter notes, at least it looks right in the master palette's symbols palette)

More appropriate setting would be this (in Valerian's metadata.json):

"glyphsWithAnchors": {
    "noteheadBlack": {
        "stemUpSE": [
            0.768,
            0.62
        ],
        "stemDownNW": [
            0.632,
            -0.632
        ]
    },

Which looks correct. But changing the x-values there doesn't seem to have any effect, while changing the y-values does take effect.

So this does indeed point at MuseScore to be ignoring the x-values.

Looking at the code:

                  // move stem start to note attach point
                  Note* n  = up() ? chord()->downNote() : chord()->upNote();
                  if ((up() && !n->mirror()) || (!up() && n->mirror()))
                        y1 += n->stemUpSE().y();
                  else
                        y1 += n->stemDownNW().y();
                  rypos() = n->rypos();
                  }
...
      line.setLine(0.0, y1, 0.0, l);

seems to confirm this

Looks good with Valerio

with some code changes

But then looks bad with Leland

No idea why, that change doesn't touch the y-values at all

At least with quarter notes... others yet to be tested

Not sure either. A 'usual' musicxml file mentions 'font' in:

<word-font font-family="FreeSerif" font-size="10"/>
 <lyric-font font-family="FreeSerif" font-size="11"/>
 <credit-words default-x="600.172" default-y="1611.03" justify="center" valign="top" font-family="MuseJazz Text" font-size="24">La Valse m39-58</credit-words>

EDIT: In the Valerio musicxcml file there is not a single mention of font (?!)

I found this problem with the AloisenGrooveU font.
aloisenGrooveU.png

I guess (almost) nobody uses this font, and it can be ignored?
The 'beam' problem also exist in Dorico. But are beams needed in 16th century printed music?

Any suggestions about a good companion text font?

OK here's how the Aloisen fonts look (with my PR in its current form)
stems-3.7-AloisenU.png
stems-3.7-AloisenGrooveU.png
Seems to be bad metadata for noteheadBlack and noteheadHalf's stemUpSE, very bad (on the wrong side of the heads) for AloisenGrooveU, only a stemwidth off for AloisenU, similar to Bravura.
Actualy the Aloisen fonts don't have a stemUpSE at all!?!

The glyphBBoxes stuff bBoxSW and bBoxNE seems to be Finale specific.
https://w3c.github.io/smufl/latest/specification/glyphbboxes.html
This data is provided primarily for MakeMusic Finale, which requires bounding box data for certain graphical and spacing calculations performed by the software.
Deleting this complete block doesn't change anything.

I also noticed that the x values do not have any effect, while the y values do work
