The "Alphabet Song" is a popular children's song used to teach the letters of the English alphabet. It is typically sung to the tune of "Twinkle, Twinkle, Little Star," making it easy for young learners to remember the sequence of letters from A to Z. This song is often used in early childhood education settings, such as preschools and kindergartens, to help children develop their literacy skills. By singing the song, children can improve their phonemic awareness and prepare for reading and writing activities.
