Greensleeves was originally a Scottish folk song, which was sung by some gold diggers in England in the16th century. This song expresses love for a beautiful woman wearing green sleeves and is used as a singing song in dance. British playwright Shakespeare (1564- 16 16) mentioned this folk song in his comedy The Merry Wives of Windsor, which shows that ordinary British people were already familiar with this song at that time. Hundreds of years later, the famous British writer Ang. Williams (1872- 1958) wrote the opera "Mr. John in Love" based on Shakespeare's "Merry Wives of Windsor", and the interlude in the third act adopted the music material of the folk song "greensleeves", which was quickly adopted by another British composer Ralph. Greaves adapted it into a theme fantasy. Of course, there are countless other forms of adaptation, such as piano duet, harp ensemble, violin solo and quartet chorus. The American film History of the Western Frontier even regarded it as an American folk song, which shows its wide spread.

The intro of Fantasia with Green Sleeve theme is played gently from the high-pitched area of the flute, and slowly stretches and slides from top to bottom, creating a quiet and beautiful atmosphere. On the clear arpeggio background of the harp, violins and violas sing the beautiful theme of Green Sleeves, which is natural, simple, cordial and lyrical, like a melody flowing from the bottom of my heart. In the second part of the music, the dance rhythm of the previous paragraph was replaced by the regular 4/4 beat, and the speed was obviously accelerated, which made the music's personality contrast corresponding and the emotional expression more enthusiastic and lively. In particular, the colorful performance of a flute was immediately introduced, and the pitch of the original music was rubbed into instrumental music by relatively free improvisation, which sounded like coloratura soprano singing. When the introduction melody sounded again, the third part of cello and viola performance repeated the theme of Green Sleeve, but its timbre became more mellow and lasting. In the end, the texture of the band became more and more vague and sparse, and the intensity became more and more gentle, as if the infinite admiration and passion in the heart finally calmed down.
