The document provides instructions for replacing strings on a kantele, a traditional Finnish plucked string instrument. It describes obtaining replacement strings, threading the looped end of the new string under the metal bar or pin, turning the tuning peg several times before threading the string, cutting off excess string and folding back the end to prevent slipping, tightening while keeping the vibrating part separated from other strings to avoid noise, checking the level of the new string, and pressing the loop against the bar before tuning and retuning as the new string stretches initially.
