Hello

7/2 tone exists on the other hand I made a mistake: 7/2 tone is not equivalent 
to 1 tone + 3/4 tone
but is equivalent to 3 tones + 1/2 tone.
Since 7/2 tone is rarely used, this part can be deleted.


                 (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))

  But it will be a mistake, I think we have to keep this, take a look at this
  (Note: It already exists in Turkish music too)
  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")
)

Best,
Jean

Shouldn't we rather change this use of 7/2 to 7/4 instead of deleting it? Or is that not the original intent?
