Yes, 15ma (I don't have enough Italian to be able to guess how 15 notes above should be expressed.) Fughetta font just uses a simple 8 or 15 above/below the G clef & F clef without any abbreviation...

Does anyone know of a 3rd-party font that includes a bass clef 15va? "Fughetta" font has a bass clef for 15 below, but I need 15 above. Thanks! Michael Sweeney.
