This is a strophe from a song:
"Well, she stands all around me her hands slowly sifting the sunshine
all the laughter that linger down deep 'neath her smilin' is free
Well, it spins and it twirls like a hummingbird lost in the morning
and caresses the south wind and silently sails to the sea"
But I'm not sure how the down affects the idea of linger. Is it necessary for the deep?
Could I rewrite the sentence this way:
All the laughter that linger (down) under her smiling is free
