I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "The written score, however, does not usually contain explicit instructions as to how to interpret the piece in terms of production or performance, apart from directions for dynamics, tempo and expression (to a certain extent). This is left to the discretion of the performers, who are guided by their personal experience and musical education, their knowledge of the work's idiom, their personal artistic tastes, and the accumulated body of historic performance practices."?
The performer's personal artistic tastes helps the performer do what?
