The abc structure of the music is a trilogy with reproduction. The music first presents the first section of a single three-section with reproduction, and then a second section composed of new material appears. After the above two sections of music are presented with dominant chords, a connecting sentence appears, leading to the third section of a single two-section with reproduction. Sections, the first section is new contrasting material, the second section begins to reproduce the material of the first section, but it also contains new contrasting factors, and finally the whole song ends on the main chord of D major.
