I just found out that changePitch is very useful to write homophonic
passages in \parallelMusic!

%%%%%%%%%%%%%%%%%%
\version "2.19.32"
\include "changePitch.ly"

\parallelMusic #'(one two three) {
  \changePitch
  { 4 8 \samePitch { 8~ 8 } 8 8 8 | }
  {
    c'' d''     e''     f''     g''     a''
    a'  b'      c''     d''     c''     cis''
    f'  g'      a'      b'      as'     ges'
  }
}

  \one
  \two
  \three

But there is still a small problem with ties.
It's not always possible to use \samePitch.

%%%%%%%%%%%%%%%%
{ 4 4~ \tuplet 3/2 { 8 8 8 } 4 | }
%%%%%%%%%%%%%%%%

Would it be possible to tell changePitch to automatically repeat the pitch
of a tied note?

I tried to understand the scheme code to find a solution by myself. But once
again I discovered the limits of my scheme-abilities very soon..
