Abstract: The theory of reception aesthetics emphasizes the relationship between text and subject, and attaches importance to the aesthetic production value of readers. From this point of view, the conductor participates in the conversion of chorus text as a “reader” in the production of chorus art, and deals with the relationship between chorus text, chorus player and chorus audience. Among them, the command role changes with the transformation of the text, which is mainly reflected in the replacement and wandering of “accept role” and “summon role”. Acceptence role is the integration of the conductor’s personal creativity and aesthetic experience. Summon role is the command to deal with the relationship between text and text, text and players, audience through action and blank filling.
