曲譜簡介：

Greensleeves is a traditional English folk song and tune, over a ground either of the form called a romanesca; of its slight variant, the passamezzo antico; of the passamezzo antico in its verses and the romanesca in its reprise; or of the Andalusian progression in its verses and the romanesca or passamezzo antico in its reprise. The romanesca originated in Spain[1] and is composed of a sequence of four chords with a simple, repeating bass, which provide the groundwork for variations and improvisation.
