Note whiteout

[Andrew Bernard]

What do I whiteout and how exactly to get the chord in the example covering the leger lines to nicely whiteout just the right things? Notehead, leger lines, stem? Not real music, just the smallest example I could make.

\version "2.19.17"

treble = \relative c'' {

  e

  \change Staff = "bass"

  <e,,, g,>

  \change Staff = "treble"

  g'' c

  c1

}

bass = \relative c {

  \clef bass

  <c, f c,>1 ~

  <c f c,>

}

\score {

  \new PianoStaff

  <<

    \new Staff = "treble" \with { }

    { \treble }

    \new Staff = "bass" \with { }

    { \bass }

  >>

  \layout { }

}
