Hi Bill,

I can't say I understand exactly *why* this is, but the "\new Voice" 
command in the Flute variable seems to be at least partly at fault. 
Normally the explicit creation of voices with this command is done in 
the \score block, and when I changed your code to do it this way it 
fixed the grace-note problem.  Someone who really understands Lilypond 
internals can correct me if I'm wrong, but I think your original code is 
telling Lilypond to create a new voice right after it has already 
created a new voice, because when you give the

\new Staff << \global \Flute >>

command, it knows to create a voice into which it will put everything, 
so the new voice already exists by the time you get to the \global 
command, and the \Flute variable is telling it to put another new voice. 
 If you remove the \new voice from your Flute variable and put it in 
the \score block it will work:

\version "2.12.0"

\header{
  title = "Initial grace note test"
}

global= {
  \time 4/4
  \key f \major
}

Flute = \relative c'' {
  \set Staff.instrumentName = #"Flute "
  \clef treble
  \grace { a'8 }
  a'16 r r r r4 r2 \bar ":|"
}

\score {
  \new StaffGroup <<
    \new Staff <<
      \new Voice = "flute" {
        \global \Flute
      }
    >>
  >>
  \layout { }
  \midi { }
}


HTH,

Jon
