Re: Forcing hshift not working...

[James Bailey]

You're right, my apologies. The problem here is that lilypond doesn't  
accomodate for an extra voice on the staff. You want to have it  
*look* partially like two voices in the upper staff, and then three  
voices. I would input it the way it looks like the voices work (which  
may or may not be how the voices are).

This solution probably doesn't work well for your input:
\version "2.12.3" \include "deutsch.ly"

\relative b' {
   \time 3/4
   \key as \major
   <<
      {
         b4 f4. g8
         b4( as2)\fermata
      }\\{
         f2.
         es2.
      }\\{
         \voiceFour
         \shiftOff
         des2.~
         \shiftOn
         des4( \shiftOff c2)\fermata
      }
   >>
}

I was able to jerry-rig the same results by simply adding proper  
voice definitions to your file:

\version "2.12.2"

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

upperA = \relative c'' {
  bes4 f4. g8
  bes4( aes2)\fermata
}

upperB = \relative c' {
  f2.
  ees2.
}

lowerA = \relative c' {
  \change Staff = "upper"
  \voiceFour
  \shiftOff
  des2.~
  \shiftOn
  des4( \shiftOff c2)_\fermata
}

lowerB = \relative c {
  g8[ aes] bes4 ees4 ~ << { ees2.\fermata }\\{ aes,2._\fermata} >>
}

\score {
  <<
    \new PianoStaff <<
      \new Staff = "upper" << \global \clef treble << \upperA \\  
\upperB >> >>
      \new Staff = "lower" << \global \clef bass << \lowerA \\  
\lowerB >> >>
    >>
  >>
}

If you want to, now you can add \once \override NoteColumn #'force- 
hshift = #-1.0 where you want, and it should work.
