Thanks, however my question about 7/2 tones is not answered: if a 7/2 
tone alteration is not used, why do the "arabic" language and 
hel-arabic.ly have not names and alterations for 7/2 alterations? To wit:

               (cshb . ,(ly:make-pitch -1 0 SEVEN-HALF-FLAT))
               (dshb . ,(ly:make-pitch -1 1 SEVEN-HALF-FLAT))
               (eshb . ,(ly:make-pitch -1 2 SEVEN-HALF-FLAT))
               (fshb . ,(ly:make-pitch -1 3 SEVEN-HALF-FLAT))
               (gshb . ,(ly:make-pitch -1 4 SEVEN-HALF-FLAT))
               (ashb . ,(ly:make-pitch -1 5 SEVEN-HALF-FLAT))
               (bshb . ,(ly:make-pitch -1 6 SEVEN-HALF-FLAT))

               (cshd . ,(ly:make-pitch -1 0 SEVEN-HALF-SHARP))
               (dshd . ,(ly:make-pitch -1 1 SEVEN-HALF-SHARP))
               (eshd . ,(ly:make-pitch -1 2 SEVEN-HALF-SHARP))
               (fshd . ,(ly:make-pitch -1 3 SEVEN-HALF-SHARP))
               (gshd . ,(ly:make-pitch -1 4 SEVEN-HALF-SHARP))
               (ashd . ,(ly:make-pitch -1 5 SEVEN-HALF-SHARP))
               (bshd . ,(ly:make-pitch -1 6 SEVEN-HALF-SHARP))


(from define-note-names.scm), and

HelmakamGlyphs = #'(
  (1 . "accidentals.doublesharp")
  (1/4 . "accidentals.sharp.slashslash.stem")
  (3/4 . "accidentals.sharp.slashslashslash.stem")
  (5/2 . "accidentals.sharp.slashslashslash.stemstem")
  (7/2 . "accidentals.sharp.slashslash.stemstemstem")
  (1/2 . "accidentals.sharp")
  (0 . "accidentals.natural")
  (-1/4 . "accidentals.flat.slash")
  (-3/4 . "accidentals.mirroredflat.flat")
  (-5/2 . "accidentals.flatflat.slash")
  (-7/2 . "accidentals.flat.slashslash")
  (-1/2 . "accidentals.flat")
  (-1 . "accidentals.flatflat")
)


Is it a workaround for the fact that LilyPond does not have a way to 
define note names for the same pitch with different accidentals?

Thanks,
Jean
