You need a comma after the g in evening. No.

Are you trying to write a cliche or describe something?

Is it important how you said good evening? Why?

Also, good evening isn't really a reply.

It seems a bit redundant. A lilt is a rhythmic or musical bounce. You could simplify it by using simply "lilt."

I don't think lilt is meant to be melodic, but rather high pitch?
but I could be wrong. Alba

Sentece? NO. You are merely describing a method of speech, not a poetic technique.
