With this description, we have automatically included a criterion called “History”, Until we know the time of the creation of a work of art, we cannot judge whether it has been easy to create or not. Suppose that, in a historical study, we find a musical work that is similar in compositional techniques (including form, melody, context, and orchestration) to a minor work of the nineteenth century; however, our research proves that, this work dates back to 200 years prior to that date.
