Re: Partial Bars

[Pierre Perol-Schneider]

Hi Bill,

here's how I'd do:

\version "2.18.2"

global = {
  \time 3/4
  \key g\major
}

menuet = {
 
  %% PART A
  \repeat volta 2 {
    % mes.0
      \partial 4 s4 |
    % mes.1-7
      \repeat unfold 7 { s2. | }
    % mes.8a
      s2 % <= no barcheck (incomplete measure)
  }
 
  %% PART B
  \repeat volta 2 {
    % mes.8b
      s4 | % <= barcheck (end of measure 8)
    % mes.9-15
      \repeat unfold 7 { s2. | }
  }
  \alternative {
    {
      % mes.16
        \set Timing.measureLength = #(ly:make-moment 1/2)
        s2 | % <= barcheck (complete measure 16)
    }
    {
      % mes.17a
        \set Timing.measureLength = #(ly:make-moment 3/4)
        s4. % <= no barcheck (in complete measure 15)
    }
  }
 
  %% PART C
  \tempo "Trio"
  \repeat volta 2 {
    % mes.17b
      s4. | % <= barcheck (end of measure 17)
    % mes.18-24
      \repeat unfold 7 { s2. | }
    % mes.25a
      s2 % <= no barcheck (incomplete measure) 
  }
 
  %% PART D
  \repeat volta 2 {
    % mes.25b
      s4 | % <= barcheck (end of measure 25)
    % mes.26-32
      \repeat unfold 7 { s2. | }
  }
  \alternative {
    {
      % mes.33
        \set Timing.measureLength = #(ly:make-moment 3/8)
        s4. | % <= barcheck (complete measure 33)
    }
    {
      % mes.34
        \set Timing.measureLength = #(ly:make-moment 1/2)
        s2 |% <= barcheck (complete measure 34)
    }
  }
  %% fine
  \bar "|."
}

\header {
  title = "Six Minuets"
  composer = "Ludwig van Beethoven"
  opus = "WoO 10"
  piece = "Menuet No.2"
}

\score {
  \new PianoStaff <<
    \new Staff = "right hand" { \global \clef G \menuet }
    \new Staff = "left hand" { \global \clef F \menuet }
  >>
  \layout {
    system-count = 5
  }
}

HTH,

Pierre

The simplest solution is likely to use version 2.19.12 or later.  Some
changes for allowing \time in connection with \partial have been
committed in 2.19.16 as well.
