How about:


\version "2.19.21"
\language "english"

% --- Definitions ---

staffUp = \change Staff = "upper"
staffDown = \change Staff = "lower"

% --- Music ---

highVoice = \relative {

  e''8 ( fs d4 |
  c8 e b4 ) |
}

upperMiddle = \relative {
  \override Rest.X-offset = #-0.5
  s8 a' g\rest <fs a>
  g\rest g e\rest <e g>
}

lowerMiddle = \relative {
  \staffUp
  e'4 d |
  c4 b |
}

lowVoice = \relative {
  \staffUp
  e'8 ( fs d4 |
  c8 e b4 ) |
}

% --- Layout and MIDI ---

global = {
  \key c \major
  \time 2/4
}

upper = {
  \global
  \clef treble
  <<
    \new Voice
      { \voiceOne \highVoice }
    \new Voice
      { \voiceThree \override NoteColumn.force-hshift = #0.4 \upperMiddle }
  >>
  \pageBreak
}

lower = {
  \global
  \clef bass
  <<
    \new Voice
      { \voiceThree \override NoteColumn.force-hshift = #0.4 \lowerMiddle }
    \new Voice
      { \voiceTwo \override NoteColumn.force-hshift = #0.4 \lowVoice }
  >>
  \pageBreak
}

\score {
  \new PianoStaff <<
    \new Staff = "upper" \upper
    \new Staff = "lower" \lower
  >>
  \layout {
    \context {
      \Score
      \hide BarLine
      \hide SpanBar
    }
    \context {
      \Staff
      \remove "Time_signature_engraver"
    }
  }
}
