Lyric in popular score

[Marcos Press]

Dear list,

Iḿ trying to add the lyric of a folk song to a score.

How do I tell the lyric in wich measure to start?

All the things I found in google, the manuals and snippets always deals lyrics starting at the same moment of the music.

What I need is

\chords { blah blah blah blah }

\music { blah blah blah blah }

\lyric { R2*15 r4. blah blah blah}

Do I have to break the music block into two blocks?

Can anyone point me where to look for an unswer?

Thanks in advance!

Marcos
