What should dancers practice before a performance to ensure success?

Systematic repetition is crucial for dancers to ensure success before a performance because it allows them to refine their movements and techniques. By practicing repetitively, dancers can build muscle memory, reinforce coordination, and achieve a greater sense of timing and rhythm. Repeated practice helps in solidifying choreography so that it becomes second nature, which can reduce anxiety and increase confidence on stage.

Emotional expression is important for a performance but generally comes after solidifying technical skills through systematic repetition. Costume fitting and audience interaction, while relevant to overall performance preparation, do not directly enhance the physical execution of dance in the way that systematic repetition does. Therefore, focusing on systematic repetition is key to ensuring that a dancer performs at their best during a performance.
