How many parts does "Butterfly Lovers" violin concerto consist of?

There are three parts: presentation part, expansion part and copy part.

1. Presentation part: In the presentation part, the spring scenery is described from the introduction, and then the scene of "love theme, grass bridge worship and theme reappearance" between Liang Zhu and Liang Zhu is described by the main part in the form of Aba with a single three-segment structure, and then a free colorful segment appears in the connection part. The second part consists of a Rondo in Abaka form, which describes the fun of Liang Zhu and his classmates for three years. At the end, I wrote the scene of two people "sending off the pavilion at the age of eighteen"; The development department wrote three scenes: "resisting marriage", "Loutai meeting", "crying, suing and throwing graves". Finally, a wonderful, mysterious and dreamlike "become a butterfly" world appeared in the reproductive department (omitting the deputy department).

2. Development Department: This is the center of the dramatic development of the whole work. The music turned into a gloomy atmosphere, and the cello and bassoon played gloomy downward phrases, as well as the gongs, timpani and discordant sounds played by the band, which created a gloomy and horrible atmosphere and heralded the arrival of tragedy. Suddenly, the bassoon, horn, trombone, tuba and bass strings played the theme of representing the cruelty of feudal forces.

3. Reproduction part: The reproduction part only reproduces the theme of the presentation part-the theme of falling in love with the ear. Accompanied by the harp, flute brings people into the realm of immortals with its wonderful and colorful melody. On the background of strings with silence, the solo violin and the first violin with silence play the theme of love ear.
