People's privacy can also be interrupted by unwanted phone calls from telemarketers and others who wish to profit in some way - just as Internet e-mail accounts receive unwanted sales pitches, known as spam.. Yet, the invention of the telephone also worked to increase privacy in many ways.
Rosin build up on violin strings can make them sound scratchy. Although applying rosin to the bow is important to create friction when the bow is pulled across the strings, too much rosin on the strings can reduce the strings ability to vibrate. Clean the rosin off your strings regularly to reduce any scratchy sounds.
Wipe a clean cloth over the body of the violin to remove any rosin dust that has been created. Rosin is slightly acidic so can damage varnish if left on the body of the violin. Check the stings. If the strings look clean, you have removed the rosin build up and the violin will sound less scratchy when it is next played. If there are patches of rosin remaining on the strings continue to the next step.
