Re: combining parts

[Mats Bengtsson]

The simplest solution is
ErsteStimme = { c''8 b' b' a' g' g' f' e' }
ZweiteStimme = { a'8 a' g' f' f' e' d' c' }
DritteStimme = { e'8 f' c' d' e' e' b a }
VierteStimme = { c'8 d' a b c' b g f }

\score {
 \new Staff <<
   \new Voice <<\voiceOne \ErsteStimme \ZweiteStimme>>
   \new Voice <<\voiceTwo \DritteStimme \VierteStimme>>
 >>
}

This solution will even combine rests if they happen in one and the same 
voice.
However, if you have simultaneous rests in all the four parts, then you 
will see
them duplicated, which may or may not be what you want. There have been
several workarounds proposed in the mailing lists and LSR to merge the 
rests.
