But if adjudicators were required to justify at least some portion of their marks against these set criteria, it would mean a well played performance couldn't be entirely discounted because they didn't agree with the MD's reading.And therein lies the root of this whole debate which CANNOT be solved because one man or more will "like" something better than another. Unless ever musical instruction on a score is to be followed exactly you cannot take away the interpretation aspect and someone will always like it that bit slower or faster etc. I guess that's what's called music eh??That's the nature of art ... subjectivity! But ... most can agree that there are technical aspects of musical performance that can be assessed clearly. The difficulty is balancing the level of musicianship (including reading by MD) shown against these basic principals.
