I was basing this improvisation on the well-known lullaby, “Twinkle Twinkle Little Star”. As with many traditional songs, the lyrics and the tune were written separately. The tune can be traced back to a French melody, called “Ah! vous dirai-je, Maman”, which was first published around the mid 18th century. Various versions of it have been used in other children’s songs (including the “Alphabet Song” and “Baa Baa Black Sheep”), as well as a number of classical compositions and Christmas carols.
