Entertainment bar definition
The performing arts bar is developed from a bar, the biggest feature is that there is a stage in the middle, surrounded by tables of guests, performing arts bar is different from a simple bar, also different from the opera house. The performance form will be a combination of karaoke and theater performance, the audience to buy tickets to the entrance, similar to the theater to see the song and dance show; The cabaret, with its comical hosts, was livelier than the theatre.
Usually in the face of young people in the society, the scene is hot and enthusiastic. The audience is both the appreciator and the participant. The actors usually interact with the audience's emotions according to the performance. The light at the show bar
The light design should take full account of the music characteristics of the song and dance, make full use of every second of time to reach a tacit understanding with the actors, with unprecedented strong visual shock and passionate interaction between the actors and the audience to provide unforgettable
The visual moment, such an artistic effect we can temporarily call its "boiling point scene". We often have the feeling that there is a world of difference between what we feel when we are there and what we feel when we watch it on television.
Why? It's all about the music. Lighting, performers together to create the scene atmosphere. And we found that stage lighting plays a very important role.

First, the design of the lamp position
With the music ups and downs, the light alternately running, wind wheel like rotation, colorful lighting design, can foil the hot atmosphere of the performing arts bar scene. Before the performance, should consider how to render the atmosphere
Set lamps, in addition to the normal face light, slap, top light, side light, backlight, general performance bar will also install shaking head lights, effect, smoke machine, bubble machine, flame machine and other equipment.
We can make a light wall in the back area of the stage, facing the audience behind the performers' performance area. The lamps of the lamp wall can choose narrow beam LED light casting and color changing lights to project directly to the stage performance area, or use narrow beam LED light casting and color changing lights to project to both sides of the stage in the light wall to produce a visual effect with impact on the stage. You can also choose to use the shaking head computer lights on the light wall in large numbers to create effects for group performances. Oscillating beam lights and high-power laser lights can be set on the ground to project beams to the back and above of the audience at a certain elevation Angle, or narrow beam AC downlights can be used to project beams to the front of both sides of the stage and make changes in running lights.
In addition to choosing the right lamps, hanging lamps on the stage also takes into account the beauty of the layout. Lamp positioning should be harmonious, beautiful, clean and comfortable, so that the stage lighting effect can be fully displayed.
For example, the stage can be arranged about 10 meters high and low steel frame columns. The round or diamond shaped aluminum alloy light stand above the stage is used as the lamp hanging device. Generally, a wide beam of LED light is used to change the color of the cloth color light, so that the layout of the light produces a sense of space, giving people a kind of exquisite beauty. This kind of lighting hanging device cloth color light practice is also suitable for stadium, square concert scene. In short, the lamps and lanterns on the stage are generally exposed to the audience in front of the case, to try to avoid the audience to produce visual, auditory limitations and other uncomfortable feeling.

Second, the role of stage lighting to extend the stage

In the integrated stage art elements, the stage lighting plays a prominent role. Stage lighting should extend its functional scope in time to include the audience as a part of the performance role. The lights can extend into the auditorium and change in a range of colors.
Vary the Angle, change the position, but to soften the light that is weaker than the stage light, so as to extend the stage, but also to highlight the leading role of the actors. At this time, the stage light is like a torch, igniting the passion of the scene. Different from the ordinary drama performance, the audience is also one of the targets of the lighting design in the performance bar. The lighting design can project beams from the stage to the audience, changing colors and rendering the scene atmosphere; Lamps can also be added on the basis of the lighting of the auditorium itself, such as shaking head computer lights and LED projection light changing color lights, which can shine directly on the auditorium, as well as on the stage. The shaking beam lamp can also be placed behind the audience and projected on the stage to render the atmosphere. In the performance process of performing arts bar, singers will have unforeseeable artistic play, so the lighting designer should have a solid theoretical foundation and rich practical experience, with superb expression ability of lighting vocabulary, and can express the real intention and deep connotation of the director and the work highly accurately, incisively and flexibly according to the needs of the scene atmosphere at any time. It can even inject the artistic elements of second creation into the works to guide the actors and the audience into the artistic realm expressed by the works, and sublimate it into a fine one integrating ornamental and artistic. In addition, the lighting design should take the audience as art participants into consideration in the design scheme, and the whole live art lighting should include the audience. We can make a vivid analogy. On the stage, the singer is like a conductor, and the audience is like a band. The light is the baton to mobilize the atmosphere of the scene, and any movement of it is profound and vital.
In short, the stage lighting of the performing arts bar should make the emotions and emotions of the actors and the audience express strong tension with the music in the colorful atmosphere and bloom the vitality of youth. This is what we want to achieve.

Three, the use of color
Color conversion is a form of expression of lighting language. The use of color in performing arts is an important means to create atmosphere.
In mobilizing the audience's emotions, we need to understand people's feelings of color, psychological and physiological inducements to produce changes. Blue, for example, gives people a feeling of calm, calm, full of imagination, while red, hot blood boiling or manic restlessness. Physiologically, warm colors lead to increased blood circulation and muscle activity, while cool colors have the opposite effect. Similarly, the human mind will also have a corresponding response to the color, when people see red, yellow and other warm colors, psychological will be excited; When we see cool colors like blue and green, we feel calm, even negative. Warm colors have the effect of arousing people's psychological excitement and regulating mood, among which vermilion and orange have the most exciting effect. Other colors with higher brightness and purity, such as yellow, are provocative. Cool colors have the effect of calming and suppressing psychological emotions, among which blue is the most cold and calm. In addition, other brightness, purity of low color, will also make people tend to calm psychological feelings. Black, which is what we call "dark scene", is also often used in performing arts. In some cases, after the climax of the music, the staff instantly cut the light to create a dark field, which gives people a psychological and emotional change such as disappearing immediately, fear, helplessness and so on after venting their feelings. Then such as lights and music burst up, will produce shocking sensory stimulation to the audience, the scene atmosphere to the peak moment. Since different colors can bring different psychological changes to people, we can create a variety of scene atmosphere according to the music in the performing arts bar. Even in the same scene, we can adjust the scene atmosphere through the change of colors, so as to realize the psychological and emotional mobilization of the audience. The use of color can give people different psychological suggestions according to the needs of music, such as warm colors are more attractive than cold colors, colors with high saturation are more attractive than colors with low saturation, and warm colors with small areas are more attractive than large areas of cold colors. However, we should set the general tone according to the general characteristics of the performing arts bar, and use colors around this tone. Otherwise, it will cause confusion and make the performing arts bar lose its characteristics and personality.
After we understand the changes that color may cause to people's psychological emotions, we can select colors according to the characteristics of music to express the idea of music and publicize its theme personality in the use of stage lighting in performing arts bar.
