Re: Grace Note Thickness

[Pierre Perol-Schneider]

Dear Thomas,

I've followed your instruction and when I code :

\version "2.15.39" 

{ 

  \clef "treble_8"     

  \time 3/8

  \stemUp

  e'4. | %2

  \slurDown

  \appoggiatura { b'32 [ c'' b' ais' ] } b'8 [ c'' b'16 \glissando e'' ] | %2

} 

this works fine (see first staff enclosed).

Problem comes with the polyphony :

\version "2.15.39" 

{ 

  \new Staff 

  << 

  \new Voice = "first"

    {  \voiceOne 

       \clef "treble_8"     

       \time 3/8

       \stemUp

       e'4. | %2

       \slurDown

       \appoggiatura { b'32 [ c'' b' ais' ] } b'8 [ c'' b'16 \glissando e'' ] | %2 

    }

  \new Voice= "second"

    {  \voiceTwo s2. }

  >>

}

( see second staff)  beam-thickness does not apply on grace notes ...

In the last LilyPond Report , the comparison of Breitkopf and the "airy" Lilypond outpout, according to Janek, is something that I agree 100% for quite a long time.

What I would like to do is, as a 1st step, to raise the beam thickness up to #.55~59.

Of course, you changed the context to \Score

Can't confirm. All grace-notes _are_ affected, but in a different
degree. I added
(Voice Beam length-fraction 1.5) to make this effect more visible:

\version "2.15.38"

music = \relative c' {
       \grace { d,16 [des] } c8 d e f

}
\score {
       <<
       \new Staff { \clef "G_8" \music}
       \new TabStaff {
               \tabFullNotation
               \revert TabVoice.Flag #'transparent
               \music
       }
       >>
       \layout {
               \context {
                       \Score
                       graceSettings = #`((Voice Stem length-fraction .5)
                                          (Voice TabNoteHead font-size -4)

                                          (Voice Beam length-fraction 1.5)
                                          (Voice Beam beam-thickness 0.5))

               }
        }
}

In graceSettings (Voice Beam beam-thickness 0.5) overrides other
alterations of beam-thickness (using an override in the file or
changing the value in define-grobs.scm), but only for grace-notes.

BTW, what do you intend at all?
