Father, father, where are you going
O do not walk so fast.
Speak father, speak to your little boy
Or else I shall be lost,
The night was dark no father was there
The child was wet with dew.
The mire was deep, & the child did weep
The rhythm changes in an appropriately unsettling way. Lines two and four end in  consonantly  rhymed ‘fast’ and ‘lost’, creating an uneasy mood.
