Make that
\new Staff {
<< \global \voices 1,2 << \sopI \\ \sopII >> >>
}
\lyricsto "2" { \new Lyrics \words }
The << >> construct puts several
expressions in parallel. In
your case, you want three things in parallel, the \global
variable, and the two voices, but if you want to use \voices
to define the voices, each of the voices inside \voices
<< >>
will have a voice style for its stem directions etc. \global
isn't really a voice, so you should put it outside. Also
note that there should be \\ inside \voices.
Alternatively, you could create the voices with the more
explicit
syntax
\new Staff {
<<
\new Voice \global
\new Voice = "1" { \voiceOne \sopI }
\new Voice = "2" { \voiceTwo \sopII }
>>
}
\lyricsto "2" { \new Lyrics \words }
in which case you can do with only one << >>.
Also note that there should be \new Lyrics inside
\lyricsto.
