lilt

I'm a little stuck... Click here to teach me more about this clue!

'a jaunty rhythm' is the definition.
(I've seen this before)

I don't understand the rest of the clue.

(Other definitions for lilt that I've seen before include "Cadence (in speech)" , "Rise and fall" , "Jaunty rhythm in music" , "Pleasant gentle accent" , "Rising and falling of the voice in speech" .)

I've seen this clue in The Independent.
