I am a professional violinist. This is an interesting article. I was actually searching for the exact reason why it takes slightly longer to truly recognise a very high note than it does a lower one.
Meanwhile, you have one error. It is not pressing hard which causes the bad sound. This is a commonly held misunderstanding. A test was carried out on orchestral violinists. In one hour they used an equivalent number of calories as one would shovelling a tone of coal. A great deal of 'pressure' is used. The raucous noise is actually produced when the bow is travelling too slowly for the weight of the arm, thereby 'cramping' the vibration of the string!
