任何艺术创作都要靠表现来完成,但各类艺术的表现都有着各自不同的形式和特征。有的艺术作品只需一次表现就能供欣赏者欣赏,这类艺术我们称之为一次表现性艺术。而有的艺术则不同,这类艺术首先需要创作者用某种符号将其创作构思记录下来,然后再由其他人将符号转换为真实可感的艺术作品,这 Any creation of art depends on its performance, but the performance of all kinds of art has its own different forms and characteristics. Some works of art can be enjoyed by appreciators in a single performance. We call this kind of art a performance art. While some art is different, this kind of art first needs the creator to record the creative concept with some kind of symbol, and then convert the symbol into the real and sensible artwork by others.
