to understand the evolution of ballet, we must not only look at the official styles and schools that have defined its history but also restart from baseline and consider the different unofficial strategies that choreographers have used to pass by the pre-existing norms. for example, while the public often sees the polished performances on stage, many are unaware of the backstage tactics used to ensure a dancer's role or positioning, techniques that are not officially acknowledged but significantly impact casting and performances. these unofficial methods have shaped ballet's evolution in ways that are not typically recorded or discussed openly, revealing a hidden layer of the art form's development.
