Lyrics not starting on 1st bar of music

[ayutheos]

Hi,

I have a song consisting of a single staff which has the following structure:

(1) Intro | (2) Part one | (3) Music only | (4) Part two

How do I add lyrics to Parts One and Two only? Section (3) is a short
4 bars of music.

I've gone through the help documentations, but didn't find anything to
make the lyrics *not* start on the first bar, or having a break in the
middle of the music.
