Hey everyone! I’m trying to make this indication on Dorico, but I can’t seem to be able to do it. I tried in the edit playing techniques, but I can’t make it. Does anyone know how to do it (The graphic sign)? Thanks!
They are in the SMuFL specification (and the Bravura font) under Wind techniques, U+E604 thru U+E606, though with a more abstract and rectangular style. If you want these trapezoidal glyphs specifically you’ll need to find a font that contains them or make them yourself in a graphics editor.
