To do this, find the number of the string that is broken. Then look on the string chart that comes with your harp and select the string according to its number. If you do not have a string chart for your harp call the harp maker and have them send a chart out to you. If it's a nylon wrapped string be sure to measure the core diameter and the diameter of the wrap. Then order a string from any of the harp string suppliers see address at the end of this article .
All harp strings are custom made for each individual harp.
After selecting the string, it is time to install it. If it is a monofilament, run it through the string hole of the soundboard, pushing it into the soundbox. Reach in the access hole with your hand and pull the string out the access hole enough to tie a knot in it. If the string is short you may want to put a loop on the other end so that it doesn't slip through the hole while you're tying the knot. This method is easier than trying to tie the knot first and then pushing the string through the hole from the inside out, since sometimes you can't see the string hole through the access hole.
