One thing to keep in mind is that we mostly hear recordings of GREAT players and from time to time live performances of ( sometimes ) great or at least very competent players. They for the most part play old Stradivarius or Guarnerius violins. These violins have their specific tone. Also, new violins have their specific tone as well. But we do not hear new violins played by the best players. This is how we are programed to believe there is only one kind of acceptable tone - that is something I disagree with, personally. I play cello and piano and the tone of pianos also varies a lot. But with some attention they all get the job done. Many times in Bach, Beethoven or Brahms I much prefer a more "steady" violin, more uniform note to note and I know from reading old books that the bright Italian violins were not liked by everybody but a more subdued tone was in fashion. Because of the fashion and fascination of old violins, new violins are not allowed fair chances by TOP players.
