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.
Rub the rosin cake slowly along the hairs of the violin bow repeatedly for five to 10 minutes if this is a new instrument and the first rosin application. Rub the rosin cake slowly up and down the bow three to five times if you have already used the bow, and it only needs a reapplication of rosin. Test the bow on the violin strings to see if it needs more to less rosin. When the level of rosin is perfect, you will hear a clear, clean sounding note.
