Little Jenny Wren waggles her tail and nods her head by her shed, the whole rhyme built from that one repeated gesture. Easy to copy along with, which makes it a natural for the youngest listeners.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
As little Jenny Wren
Was sitting by her shed.
She waggled with her tail,
And nodded with her head.
She waggled with her tail,
And nodded with her head,
As little Jenny Wren
Was sitting by the shed.
