Twinkle, Twinkle, Little Star is a popular English Nursery Rhyme first published as a poem called The Star in 1806 by Jane Taylor. It is sung to the tune of the French melody "Ah vous dirai-je, maman", which was published in 1761 and later arranged by the famous composer Mozart.
An alternative version of the lyrics were famously used by Lewis Carroll in his 1865 novel Alice's Adventures in Wonderland. In this case the Mad Hatter recited the poem as Twinkle Twinkle Little Bat.
I'm very grateful to Mari Nallos for doing such an amazing job of singing this lullaby.
