Re: font size override and grace notes

2012-10-18 Thread Matt Cary 

  better use \once to override the size of the g, or revert the note heads
  size after the slashed grace is done:
 
  \override NoteHead #'font-size = #4g
  \slashedGrace  a16( 
  \revert NoteHead #'font-size  b8)
 
 In this particular case, it would likely be safer to use a \tweak.
 tweaks are not timing-related and thus are impervious to the quirks of
 grace note timing.
 

Thanks for the advice. I guess I'm surprised the revert doesn't happen 
immediately. This arose in a more complicated context where I don't think 
doing tweaks is relevant; the initial override is from a function where I'm 
notating a strum.

strumFn = 
#(define-music-function
  (parser location strums)
  (ly:music?)
   #{
  \set squashedPosition = #-2
  \override NoteHead #'style = #'slash
  \override NoteHead #'font-size = #1
  \override Beam #'positions = #'(4 . 4)
  \override Stem #'length = #8
  \override Accidental #'stencil = ##f
  \override AccidentalCautionary #'stencil = ##f

  \stemUp
  #strums
  \stemNeutral

  \unset squashedPosition
  \revert NoteHead #'style
  \revert NoteHead #'font-size
  \revert Beam #'positions
  \revert Stem #'length
  \revert Accidental #'stencil
  \revert AccidentalCautionary #'stencil

   #})

\new Voice = melody \with {
\consists Pitch_squash_engraver 
} {
 \strumFn { c8[ c] } \acciaccatura a'16 b'8
}

\version 2.16.0

  { #strums

#})
 
 \new Voice = melody
 {
  \strumFn { c8[ c] } \acciaccatura a'16 b'8
 }
 

Adding an extra voice makes it hard to put in lyrics that are sung to both 
the strumming as well as the plucked notes:


\new Voice = melody
{
 \strumFn { c8[ c] } \acciaccatura a'16 b'8
}

\new Lyrics \lyricsto melody { when I sing }


I'm still not clear why this is happening in the first place. Why should the 
revert affect an override that occurs in the following expression?

 It is not following.  Grace notes go back in time.
 

Ah, thank you. I didn't know that. I see why it's a tricky situation. I guess 
that means my current workaround isn't so bad after all:

g8 \strumE d,8 \strumE |
% Something weird with the strum to the grace note.
\once \override NoteHead #'font-size = #-2 \slashedGrace a'16( b8)

font size override and grace notes

2012-10-17 Thread Matt Cary 
 I'm not top posting.

Sorry if this is a dup. I did a quick web search, and code.google.com 
search, and didn't see anything close.

The following doesn't do what I'd expect. The grace note has the large 
font size; I'd expect it to be its regular size (ie, small). Let me know if you
need any more information or context.

\relative c' {
 \override NoteHead #'font-size = #1
 g
 \revert NoteHead #'font-size
 \slashedGrace a16( b8)
}

\version 2.16.0
