See To globally change a single musical element’s font and To change the chord font. Any new articulations added to the document will display using the selected font, but existing articulations will not be changed. If you choose not to use one of these fonts, you can substitute any other SMuFL music font, but you cannot change it to a non-SMuFL font (and vice versa).
Finale's default documents use one of MakeMusic's SMuFL-compliant default fonts, Finale Maestro or Finale Broadway.
The Default Music Font defines which font is used for notational elements like noteheads, rests, tablature, accidentals, key signatures, time signatures, and articulations in a document.
