Dear Brian,
here you are:
\version "2.20.0"
\paper {
#(define fonts
(set-global-fonts
#:music "mtf-arnold"
#:brace "emmentaler"
#:roman "Futura"
#:sans "sans-serif"
#:typewriter "monospace"
#:factor (/ staff-height pt 20)
))
#(add-music-fonts fonts 'emmentaler "emmentaler" "emmentaler"
feta-design-size-mapping (/ staff-height pt 20))
}
{
as
\once \override Staff.Accidental.font-family = #'emmentaler
\once \override NoteHead.font-family = #'emmentaler
as!
}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
You need to define a name for the standard font ('emmentaler) and then
you can use it on objects (here Accidentals and NoteHeads).
Cheers,
Joram
