A melody going back officially to 1835 but used by Mozart decades earlier. It is best known as the tune for the nursery rhymes "Twinkle Twinkle, Little Star" and "Baa, Baa, Black Sheep." This and numerous other musical eCards (FredGrams) are designed expressly for young parents (and grandparents) to teach their children the alphabet and, in addition, acquaint them with classical music and great composers.
