\parallelMusic and \relative

[Werner LEMBERG]

It seems that \parallelMusic doesn't work with \relative.  This makes
it very unnatural to work with.  Any chance to implement something
similar, say, a special mode where the first note in a `section' is
absolute and the remaining notes relative to it?

  \parallelMusic #'(foo bar) {
    c'' d e |
    a' b c |
  }

    -> c'' d'' e''
       a' b' c'
