Abraham,
I make a lot of lead sheets, and I do the following:
%%%
\version "2.19"
\layout {
\override LyricText #'font-size = #2
}
Chords = \chordmode {
c2 e2:m
}
Music = \relative c' {
c4 d4 e4 f4
}
Lyrics = \lyricmode {
Do re me fa
}
<<
\new ChordNames { \Chords }
\new Staff <<
\new Voice = "Verse" { \Music }
\new Lyrics \lyricsto "Verse" { \Lyrics }
>>
>>
%%%
You can add multiple lyrics to the same music -- for multiple verses. And when there are slight rhythmic variation that you don't want to notate, you can use \new NullVoice to add a hidden voice to an existing staff, as shown below.
%%%
<<
\new Staff <<
\new Voice = "VerseA" { \MusicA }
\new Lyrics \lyricsto "VerseA" { \LyricsA }
\new Lyrics \lyricsto "VerseA" { \LyricsB }
\new NullVoice = "VerseC" { \MusicC }
\new Lyrics \lyricsto "VerseC" { \LyricsC }
