If everything is dependent on my own perception of it, I wouldn't need ever to listen to Bach or Mozart to get my doses of "beauty" or "greatness". I could simply create it all myself.
"On the other hand, for the French, Mozart was certainly not 'one of us' from a national point of view. At the beginning of the nineteenth century, before Berlioz's time, some influential critics - for instance, Julien-Louis Geoffroy - rejected Mozart as a foreigner, considering his music 'scholastic', stressing his use of harmony over melody, and the dominance of the orchestra over singing in the operas - all these were considered negative features of 'Germanic' music."Statements about aesthetic value are normally presented and understood as conditional propositions: If one accepts that certain qualities and principles are the basis of aesthetic value in musical works (of a certain style, era, etc.), then here is an objective argument for the existence of such qualities and the successful fulfillment of those principles in a given work. Obviously, if one doesn't accept the values and principles on which the argument is premised, then one won't accept the conclusions. ... It doesn't ultimately come down to opinion, it comes down to more or less objectively verifiable claims made within a system of shared values, with the understanding that the values and the claims are always subject to challenge.
-Groups of people who did not think highly of Mozart's style have existed in the past. Just cause majority of them are dead now, it doesn't mean they were "objectively wrong". If "greatness" changes with time, how can be "absolute"? At certain points in history, they weren't just a "minority", but a dominant group, and it's probably how Una cosa rara eclipsed Le Nozze di Figaro in popularity back then.
-How much of Mozart's traits is a result of "different style" and how much is a result of "superior quality" is, still to this day, largely a matter of subjective opinion and perception. Things can be and have qualities to be popular. "Greatness" is something fans use to frame and attribute to things they love and want to glorify. If something is to be considered unquestionably "great" just cause it has a lot of fans; it would be "tyranny of the majority".
