"Twinkle Twinkle Little Star," is fast becoming common in cultures around the world as of 2015; Japanese and Chinese translations exist. The melody, which is older than the song, is a French children's folk song melody, "Ah vous dirai-je, Maman," and is identical to the melody of "The Alphabet Song."
Poet and novelist Jane Taylor wrote the original poem, which first appeared with music in 1838. In 1782, Wolfgang Amadeus Mozart composed a collection of theme-and-variations on the original melody whose corresponding lyrics roughly translate as, "Oh, Mama, I say to you."
Other variations of the melody form the basis of Christmas songs in Hungary, Germany, the Netherlands and Spain.
