Greensleeves is a song from the 1500s. People say King Henry VIII wrote it about Anne Boleyn, but that is probably not true. Greensleeves is in minor key. Its verses have a (CESH) pattern, and it has a major key chorus. Ending traditionally Tierce de Picardie.
The Christmas song "What Child Is This?" is sung to the same music as "Greensleeves" but the words are different.
