As I see it, the major requirements for a strong and able rendering are an understanding of a work's structure, voicing, and trajectory; an ability to execute the details on the page from largest to smallest; technical command, and hopefully a connection with the overall expressive impulse (though the latter is not at all necessary to give a good performance).
