Describe the aesthetics and occurrences of the performance. For example, describe the setting to a ballet performance, or the subject matter of a comedy routine. Be detailed with the description, providing your own interpretation or quotes from the performer when possible of why specific props or acts were included in the presentation.
Determine the theme or message of the performance. Answer questions such as, "What exactly was the performer trying to convey?" or "How was the audience supposed to have reacted to the performance?" These will give you insight into the work while providing substance for your critique. It might also be helpful to critique the performance from a specific perspective, such as a feminist critique or a philosophical approach.
Compare the performance with others of its kind. This will allow you to measure the impact and success of the display. For example, how would this particular dance performance measure up against other choreographed numbers in a similar style? Make note of specific players who helped or hurt the power of the piece.
Detail areas where the performer or production crew succeeded at conveying their intended message, as well as how the performance could have been improved. A critique should be unbiased, even though it is from your own perspective. This means internalizing the piece enough to measure your own emotional reaction while also being able to put yourself into the role of an outsider who has not yet experienced the piece.
