Proper care of a violin is essential for maintaining its sound quality and longevity. Regularly check the strings for wear and replace them as needed. Wipe the body of the violin with a soft cloth after each use to remove rosin dust and moisture, which can damage the wood over time. Store the violin in its case when not in use to protect it from temperature changes and physical damage. Avoid exposing the instrument to extreme humidity or dryness, as this can cause the wood to crack or warp. Regularly inspect the bow and rehair it when necessary to ensure optimal performance.
