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.
ICE means Immigration and Customs Enforcement. ICE is the immigration police for the federal government and is responsible for enforcing immigration laws.
Or, ICE encourages local law enforcement officials to use integrated criminal/immigration databases or ICE fingerprint checks. A detainer or immigration hold is placed on those in custody, preventing their release from jail and ensuring that they will only be released to ICE custody.
