A galloping nonsense rhyme built largely from made-up words like gamberally and niggledy piggledy. The fun is entirely in the sound and speed of it, not in the sense.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
Master I have, and I am his man,
Gallop a dreary dun;
Master I have, and I am his man,
And I'll get a wife as fast as I can;
With a heighty gaily gamberally,
Higgledy piggledy, niggledy, niggledy,
Gallop a dreary dun.
About this rhyme
A nonsense rhyme kept alive mostly by its sound: "heighty gaily gamberally, higgledy piggledy, niggledy niggledy" is there to be enjoyed rather than understood.
Children often love the tongue-twisting refrain long before they work out what the rhyme is about.
