Grace Note Thickness

Pierre · Mai 23, 2012, 12:23

Hi Groups,

few months ago Thoms Morley (found thanks too Google) sent this code, wiche works fine :

···

\version "2.14.2"
%\version "2.15.20"

music = \relative c' {
        \grace { d,16 [des] } c4
}
\score {
        <<
        \new Staff { \clef "G_8" \music}
        \new TabStaff {
                \tabFullNotation
                %\revert TabVoice.Flag #'transparent % comment in with "2.15.20"
                \music
        }
        >>
        \layout {
                \context {
                        \TabVoice
                        graceSettings = #`((Voice Stem length-fraction .5)
                                           (Voice TabNoteHead font-size -4)
                                           (Voice Beam beam-thickness 0.1))
                }
         }      
}

Now I would like to understand this :

\version "2.15.39"

music = \relative c' {
        \grace { d,16 [des] } c4
}
\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 beam-thickness 0.1))
                }
         }      
}

affect both staff and tabstaff grace notes (see *3.png)
BUT, when thickness is increased :

\version "2.15.39"

music = \relative c' {
        \grace { d,16 [des] } c4
}
\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 beam-thickness 0.45))
                }
         }      
}

affect ONLY tabstaff grace notes. (see *4.png)

if I change, for example, (beam-thickness . 0.48) to (beam-thickness . 0.58) in the define-grobs.scm file this DOES NOT affect grace notes. (see *5.png)

Thanks in advance

Please forget question 1), my mistake.
Infact, for some reason beams appears thicker in tabstaff.
But what about question 2) ?

BTW, what do you intend at all?

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

BUT, when thickness is increased :

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}

}

\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))

}
}
}

if I change, for example, (beam-thickness . 0.48) to (beam-thickness .
0.58) in the define-grobs.scm file this DOES NOT affect grace notes. (see
*5.png)

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?

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 ...

I'm not aware I gave you any instructions.

I just ment that I've change the beam-thickness in the graceSettings file.
Sorry for the missunderstanding and for my poor english. :S
