When to use it
Place [Ad-lib] directly above the lyric lines it should control.
Common mistake
Putting full lyric lines inside brackets, which can cause Suno to sing command text.
Better pattern
Use the tag as a header, then write clean lyric lines underneath it.
[Ad-lib] usage example
(Yeah, uh-huh)
Better prompt pattern
[Ad-lib: clear section purpose, matched syllables, focused vocal energy] Write the lyric lines below the tag.
