The song Moon is from Korea and the lyrics were translated into English. The book and the CD recording are bilingual, with words in both Korean and English. An English transliteration is provided so children who don't know Korean can sing the original lyrics. Throughout field testing in the United States and Korea, children obviously enjoyed being able to sing in a second language. The reflective nature of the moon is wonderfully conveyed by the illustrator's oil painting techniques and the Seoul Philharmonic Orchestra's performance.
