The easiest way to add lyrics to a melody is to append
\addlyrics { the lyrics }
to a melody. Here is an example,
\time 3/4
\relative { c2 e4 g2. }
\addlyrics { play the game }
More stanzas can be added by adding more
\addlyrics sections
\time 3/4
\relative { c2 e4 g2. }
\addlyrics { play the game }
\addlyrics { speel het spel }
\addlyrics { joue le jeu }
The \addlyrics command is actually just a convienient way
to write a more complicated LilyPond structure that sets up the
lyrics. You should use \addlyrics unless you need to do
fancy things, in which case you should investigate
\lyricsto or \lyricmode.
{ MUSIC }
\addlyrics { LYRICS }
is the same as
\context Voice = blah { music }
\lyricsto "blah" \new lyrics { LYRICS }
\addlyrics cannot handle polyphony.
