Hello, Kees:
\version "2.6.5" << \new Staff { \time 4/4 \key es \major \clef treble \relative{
Note the additional << >> surrounding your parts here:
<< {<bes' es g>4 <bes es g> r8 <bes es g>4 <bes es g>8} \\ {c,2 es} >>
Then continue...
} } >>
So the syntax for single-staff polyphony is << { voice1Notes } \\ { voice2Notes } >> Best wishes, Kieren. _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
