Would you please introduce the violin music Butterfly Lovers?

The violin concerto "butterfly lovers" adopts sonata form, and selects three main plots in folk stories "butterfly lovers", "Ying Tai Don't Marry" and "Butterfly at the Grave" as the contents of music presentation, development and reproduction respectively. The content of the work is as follows: 1. At the beginning of the music, under the background of string vibrato, the flute played a beautiful and gentle melody, as if depicting the beautiful spring scenery and the story background of flowers and birds on the way to school in Liang Zhu. The theme sound of oboe performance is taken from the music of Yue Opera. 2. The submission department (1) falls in love: Accompanied by the harp, the violin plays a love theme that has been sung for ages. This theme is based on the music materials of Yue Opera. The author was once an actor of Yue Opera Troupe. As far as he knows, any Shaoxing opera actor singing this aria will win the applause of the audience. Therefore, the author chooses this aria as the love theme of Butterfly Lovers and takes it as the core tone of the whole work. The melody characteristics of this theme are constantly ups and downs, which seems to show Liang Zhu's yearning and pursuit for a happy life and beautiful love. The decline seems to indicate the twists and turns of their lives and the pain of having a lover who can't get married. Here, the solo violin is transferred from the high-pitched area to the middle-pitched area, and the cello "sings" with the solo violin in a unique tone, forming an answer, as if depicting the scene of Liang Zhu's "Grass Bridge". Subsequently, the band played this theme with emotion, which fully showed the mutual appreciation of Liang and Zhu. (2) The connecting part: the cadenza of violin solo. In the cadenza, the band usually stops playing, and the soloist gives full play to his playing skills. The performances here are more free and more difficult, so they are more eye-catching. Composers use cadenza here, making it an integral part of their works and a paragraph with independent characteristics. (3) Subverse: It is the most brisk and joyful passage in the whole work. The entrance of Yue Opera was changed to violin solo, which is in sharp contrast with the lyric theme of love. The first insertion speed is a lively allegro, which is modeled after woodwind instruments and violin solos. The speed of two plugs is more relaxed and cheerful. Speed is an important means of musical expression. The composer vividly described the happy time of Liang and Zhu for three years with light speed, relaxed rhythm, beating melody and lively emotion. (4) The last part: The music adopts Adagio of Regret, and its material is based on the theme of love. The composer skillfully used two pauses at the end, which made the music intermittently and delicately depict the complex mood of Yingtai in the face of Shanbo who came to see me off. The lingering melody, slow speech speed, with infinite sadness and regret, make people seem to see Liang Zhu send each other a shot like eighteen. It's really "deep in the ocean, a classmate of three years, a mountain man Zhu Yingtai". 3. Unfolding department (1) resists marriage: when people are still immersed in the atmosphere of farewell beam, the bass and cello suddenly burst into deep sounds, and the vibrato of timpani and strings is mixed with terrible gong sound. The ominous signs indicate that tragedy is about to happen. Then, the brass tube played a theme representing feudal forces with a harsh rhythm and a gloomy tone. This is the first theme of the Ministry of Development, and every phrase of this theme has a pause, which vividly shows the cruelty of feudal forces with strong power. Then the solo violin narrates the panic of Yingtai with the rhythm of national drama, which is the second theme of the development department. The phrase in this theme adopts a strong syncopation rhythm, and at the same time, with strong strength, it shows the scene that Britain and Taiwan swear to resist marriage. Here, composers use appropriate rhythm and intensity to deepen the music content and achieve more infectious effects. The first and second themes of the development department appear alternately and constantly strengthen, and then the band set off the decisive resistance tone of the violin with a strong allegro rhythm, forming a tragic scene of anti-marriage and setting off the first climax of the whole contradiction and conflict. Finally, the powerful feudal forces took the lead, the music suddenly turned into adagio, the solo violin played a crying tone, and the music turned to the part of "meeting on the balcony". (2) Lou Dai Hui: The melody is based on the chorus melody of Yue Opera Lou Dai Hui, and the timbre is long. Here, two different timbres, cello and violin, are used to ask and answer questions, which makes people seem to see the touching picture of Liang and Zhu crying and talking to each other. Tone is an indispensable means to shape the image of music, because the mellow and deep tone of cello is close to male voice, while the beautiful, bright and soft tone of violin is close to female voice. Therefore, the composer used cello solo to represent Liang Shanbo and violin solo to represent Zhu Yingtai. Through the sharp contrast between the two timbres, he vividly showed people the moving picture of Lou Daihui. (3) Mourning: The music suddenly turned sharply, and the strings adopted a fast syncopation rhythm, which was passionate and decisive. The solo violin and allegro played by the band appear alternately in the rhythm of scattered boards, and are sung slowly in Beijing Opera and Yue Opera, which profoundly describes the scene that Yingtai threw herself in front of Shanbo's new grave and cried. Here, the violin draws lessons from the performance techniques of national musical instruments, and makes more use of the expression techniques of China traditional opera in harmony, orchestration and the whole process, vividly depicting the grief-stricken mood of Yingtai. Then, drums, boards, gongs and bowls rang, and Yingtai threw herself at the grave to make a final resistance to the dark feudal forces. At this time, the band poured out their resentment and sympathy with the strongest force, and the music reached its climax. 4. Reproduction Department become a butterfly: Flute makes music return to peaceful and quiet atmosphere with gentle strength and slow speed. The wonderful melody of the flute, combined with the sliding of the harp, brings people into heaven and fairyland. Under the background of silent strings, the first violin and solo violin once again played an unforgettable love theme, like bundles of colorful butterflies, willing to dance among the flowers and tell their immortal love.
