The main thesis of the article is the problem of moral implications of the “authenticity”category. The author – in a form of moral tale – hyperbolically describes the fact thatidea of fulfilling the intention of the composer as the necessary condition of authenticperformance became a source of constraint of performers’ self-creation and expression.The discussion about authenticity, prevailing in the eighties and nineties, as well as contemporarystatements of musicians representing historically informed practice movementbring our attention to the transformation of authenticity concept from strict realisationof (imagined) composer’s intention to more flexible (and modern) interpretation creatingan identity of the musician. Finally comes the thesis about incompatibility of moral andaesthetic judgement – the author finds the second one more appropriate to evaluate musicalperformances (also performances of early music).
