To get the best match with other pieces being supplied to the same publisher I am using the Bravura font instead of Emmentaler. However, the change-clef glyphs in this font are notably smaller than usual, and I've been asked to enlarge them. I know how to use the full size clef glyphs, but that's not an acceptable solution, and I cannot find any size property attached to clefs which I could tweak. Am I missing something simple, or do I have to find a way to change the glyph in the font?
