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.
As mentioned squeaks can be caused by lots of things. If it is on the E string as well as a finger tip touching the string it could be the base part of the finger or the inside of the LH. Check that the violin is clean of rosin, especially at the bridge, and that there are no little bumps, bits of fluff from a cleaning cloth, or any stickers catching on the fingerboard.
