ignoring too many clashing note columns

[Helge Kruse]

Hello,

I try to write a guitar score. In some measures I found small parts of 
polyphony. I tried to add temporarily a new voice, but I failed. The 
example below shows the intention. The second (commented) line gives 
nearly the same result and Lilypond doesn't show any error. But the g8 
should be sound longer. That's why I want to tie it to a g4.

Can I add this temporarily polyphony on demand or must it start at the 
first measure filled with lots of silent rests?

Any suggestion is welcome.

        \relative c'' {
                c'8   b16 a~ a g16 g8~  << { g4 } \\ { fis8 e } >>
%               c'8   b16 a~ a g16 g8   fis8 e
        }
        \\
        \relative c'  {
                a16 e'8. e e,16~e b''8 e,,16
        }
        >>
}
