Re: Rehearsal marks and grace notes at the beginning of bars

[Flaming Hakama by Elaine]

Patrick,

Thanks for your explanation and advice.

The only question I have is in terms of what you consider to be the appropriate fix, which amounts to adding grace note rests to every other part. 

In this case, it is not much of an issue since this is just a trio piece.  But if I were working on a larger orchestration, this seems like kind of a lot of work, modifying every other part, rather than just modifying the one part that has the grace notes. 

I am wondering if I am missing something about the character of the problem and the solution that makes you recommend the grace note rest approach, rather than tweaking the order of the grace notes and rehearsal mark in the part that actually has them?

Thanks,

See v.2.19.15 Notation Manual, Section 1.2.6, "Special rhythmic concerns", subsection "Grace notes", subsubsection "Known issues and warnings":  Grace note synchronization can also lead to surprises.  You just ran into a surprise.

LilyPond has problems when (I think) it gets into negative time on one staff and not on a concurrent one.  Grace notes apparently lead to negative time after bar lines.  The following snippet is equivalent to yours with all the stuff irrelevant to your issue removed, and shows the four possible cases:

\version "2.19.5"

violinOK = \relative c'' {
   \mark\default \grace e16  e4 r r2
}

violinBroken = \relative c'' {
  \grace e16 \mark\default e4 r r2
}

clarinetBroken = \relative c' {
  \mark\default R1
}

clarinetFixed = \relative c' {
  \mark\default \grace s16 R1
}

global = { \key g\major }

 \score {
    <<
     \new Staff { \global \clarinetBroken }
     \new Staff { \global \violinOK }
     >>
 }

 \score {
    <<
     \new Staff { \global \clarinetFixed }
     \new Staff { \global \violinOK }
   >>
 }

 \score {
   <<
     \new Staff { \global \clarinetBroken }
     \new Staff { \global \violinBroken }
   >>
 }

 \score {
   <<
     \new Staff { \global \clarinetFixed }
     \new Staff { \global \violinBroken }
   >>
 }

In my viewpoint, the original violin part wasn't broken, so it didn't need fixing.  The clarinet part needed the fixing.  So what you call violinBroken I call violinOK, your clarinet is my clarinetBroken, my clarinetFixed, which you don't have, follows the cited warnings, and your violinFixed is my violinBroken.

HTH.
