When there are no lyrics at all to play with a given pair of chords, the corresponding “empty line” is represented by a …. This acts as a reminder to wait until the next pair of chords before starting singing again.

For instance:

Slip inside the eye of your mind          [Verse]
Don't you know you might find         C G Am E7
A better place to play - …            F G C  Am-G
You said that you'd never been
But all the things that you've seen
Slowly fade away

Translates into:

Chords Line
C G Slip inside the eye of your mind
Am E7 Don’t you know you might find
F G A better place to play
C Am-G (no lyrics)
C G You said that you’d never been
Am E7 But all the things that you’ve seen
F G Slowly fade away
C Am-G (no lyrics)
