+ * clefs: The names I'd like are of the form
+
+ [FGC]n{[_^]8} F, G or C clef, on nth line, subscripted
+ or superscripted with an 8.
+ So:
+ G, G2, treble, (== current `violin') G clef on second line.
+ F, F4, bass (== current `bass' ) F clef on fourth line
+ G_8, G2_8 G clef on 2nd line, with 8 subscript
+ G^8 G clef on 2nd line with 8 superscript
+ C1, soprano (==current `soprano') C clef on first line.
+ C2, (==current `mezzosoprano') C clef on second line
+ C3, alto (==current `alto') C clef on third line
+ C4, tenor (==current `tenor') C clef on fourth line
+ C5 (==current `baritone') C clef on fifth line)
