4、 Emotional art design of fashion stage lighting

（1） The relationship between light change and music melody

If the lighting design is properly matched with the performance, it can add "luster" to the music. It makes the audience integrate into it, experiencing joy, anger, sadness and joy. For example, the Erhu Concerto "Er Quan Ying Yue" adapted from the erhu music "Er Quan Ying Yue" by musician Mr. Hua Yanjun. When the Central National Orchestra performs on the stage, the author uses bright lights and color changes to accompany the melody of the music, so that the audience seems to return to the years displayed by the music. When the curtain slowly opened, the stage area was covered with light blue light, a round of waning moon was hanging high on the sky, and a bunch of cold light was shining on the erhu soloists. With the shaking of the bowstring in the hands of the performers, the sad music brought people to the dark old society. The music makes people feel as if they see an old man in rags, hobbling in the dim moonlight. He says that he should not cry every day, and he doesn't know to whom he can tell his sorrow and sorrow. The blue light shows the background of the times, and integrates the meaning of the music. At this time, the whole music reaches its climax, and the stage is illuminated by the red light. We seem to hear his anger from the bottom of his heart to the ultimate cry, which is not only a struggle against fate, but also a yearning and pursuit for a better life. With the passionate ending of the music, the stage is bright, Let people see the light and hope, at the same time let people see that the light is inspired by music, but the music is extremely touching.

（2） Contrast the different expression of color in works

The large-scale national orchestral concert "hardship and brilliance" commemorating the 90th anniversary of the founding of the Communist Party of China reflects the historical picture of the CPC leading the Chinese people from hardship to brilliance, which gives lighting designers more creative space. The author makes full use of brightness, color, distribution and change to give play to "light is the essence, color is the phenomenon", and try to achieve the artistic effect that composers and conductors want to achieve. The national orchestral Overture narrates an important period in the history of the party's development, with the three major events of the Long March, the war of resistance against Japan and the war of liberation as the core, to express the author's patriotic feelings. The National Orchestra and Chorus "Ode to the rivers and mountains" is composed of four representative songs of different periods, namely "Liuyang River", "story of spring", "entering a new era" and "Jiangshan". With beautiful narrative melody, the band plays the theme of winding and beautiful Liuyang River. The background of the stage is ten songs and nine bends, with clear waves and beautiful riverside scenery of green mountains and branches on both sides. In order to make the color of the performance area more transparent and thick, the author has equipped 8 computer dyeing lights at the first, second, third top, reverse one and reverse two positions. At the same time, dozens of LED computer lights are added to the top light and Bridge light on both sides to make the whole performance area bright and thorough, so that the audience can feel the great rivers and mountains of the motherland vividly and have a panoramic view of Jiangnan; The music is transferred to the story of spring, and the performance area is quickly transformed into a light with green as the keynote along with the rhythm of the music, making people feel as if they were in the youth of the early days of China's reform and opening up; In the third movement "into the new era", the light in the performance area gradually turns to pink with the music, the atmosphere of the light turns from "cold" to "warm", and the rhythm of the change is gentle, blending the change of the light into the music; Such a lighting change process, coupled with the fresh and progressive music, creates a happy life atmosphere for the people after 20 years of reform and opening up; In the last distant view piece "Jiangshan", the music reaches its climax. With the orchestra conductor's gesture, the performance area uses fast rhythm, and the whole scene is bright and full of brilliance. Because the light is in a "warm" tone, the stage is brighter by contrast. The rhythm of the music and the rhythm of the lighting are like an impact force, which makes the audience's mood suddenly bright and excited with the music.

5、 The trend of stage lighting in the future

Stage lighting is one of the most active and active elements in stage art, which can dynamically cooperate with music or drama performance. The innovation and development of science and technology will always catch up with and surpass the needs of artistic creation and development. The development of lighting technology is conducive to the creation of lighting art, but it does not determine the success or failure of lighting art creation. The key lies in the lighting designer's attitude, angle and control ability of lighting technology, using "lighting to depict the stage" to enrich the life of stage art, It is always the most clear and happy goal for every designer.

With the continuous progress of science and technology and the change of people's aesthetic vision, designers should constantly enrich their music cultivation, adapt to the changes of the times, and constantly enrich their stage expression with high-tech technical means. As an artist, he should stand in the front of the times and combine the essence of the nation with modern fashion to create a new era of fine art.
