Is it possible to switch the music font for a staff or even a measure
with your approach? Or does it only work in the \paper environment.
It would be cool for comparisons of fonts in the same file like here
(using oll):
\version "2.18.0"
\include "custom-music-fonts/smufl/definitions.ily"
music = \relative c' {
\clef alto
\time 3/4
c4-.(\f\< d4-. es4-.) |
\time 4/4
fis8.---\trill\sfz\> e!16\downbow d16->\! r16 r8 c2-\prall |
\time 2/2
\clef treble
r2-\fermata c8( eeh8)-^ \tuplet 3/2 { eeh8( gisih8 b')-! } |
}
<<
\new Staff \with { instrumentName = "Feta" } \music
\new Staff \with { \bravuraOn instrumentName = "Bravura" } \music
Just changing the font name of all objects does not seem to work.
Cheers,

YES!, this can be done quite easily. As I explained on my personal
website (the link is found near the bottom of fonts.openlilylib.org),
https://sites.google.com/site/tisimst/Home/custom-font-how-to#localized-font-changes
You can use another built-in function "add-music-font" to provide
instant access to any of the music fonts I've published (with one
kind-of-caveat I'll explain in a moment). The "add-music-fonts"
function puts associates the music fonts with the proper glyph encoding
(i.e., NOT "latin-1", which is what the text fonts use). For example,
say we wanted to make Profondo locally available, we would do something
like:
\paper {
#(add-music-fonts fonts
'profondo % <--- this is the variable you will use to access the
font
"profondo" % <--- the music font name
"emmentaler" % <--- the piano brace font name
feta-design-size-mapping % <--- required, don't change
(/ staff-height pt 20))
}
At this point, Emmentaler is still the global document notation font.
However, whenever you want to change any notation element to be from
the Profondo font, all you need to do is:
\override [LayoutObject].font-family = #'profondo
This can be done on-the-fly like any other override or score-wide in a
\layout block.
THE KIND-OF-CAVEAT
It's not really a caveat, but here's the only catch to changing music
fonts this way. After a while of playing around with LP and its font
mechanisms, I realized that this is NOT a great way to change the
global document music font. If you do some searching online, you might
find something like this (which is similar to what you'll find in
"ly/paper-defaults-init.ly"):
\paper {
#(define font-defaults
'((font-family . profondo) (font-encoding . fetaMusic)))
}
The reason this isn't a great way to change the font globally is
because it doesn't catch every layout object. You have to add
additional \layout overrides to DynamicText, Fingering, Script,
TrillSpanner, and a host of other layout objects in order to get
everything. BUT, if all you want is a local \override, then the syntax
I showed above is all you need. Now you can write variables to change
things just like is done with \smuflOn and \bravuraOn.
HTH,
Abraham
