Changing a Lever Harp String

Step-by-step directions on how to change a harp string on your Rees Concert Line Lever Harp.

Lever harps are often also called Irish harps or Celtic harps. We are also the makers of Harpsicle® Harps. Rees has been building harps since 1972. Our harps are hand crafted in Rising Sun, Indiana, United States.

How to Change a String on Your Rees Harp

It will happen. Your harp will break a string. It is possible for strings to break a day after they have been put on or to survive for a decade or more. One fortunate thing is that harp strings rarely need to be changed. Harp strings are not like violin or guitar strings and they do not go "dead" in the same way. Monofilament nylon strings only need to be changed if they break, nylon/nylon about every two years or so (if you play frequently) and wire wrapped strings once a year (again, if you play frequently.) Additionally, unlike a guitar or many other stringed instruments, we strongly recommend against ever changing all the strings on a lever harp at the same time.

The first time you change a string it may seem difficult but it quickly becomes easier with experience. The respected harpist Sylvia Woods has a very detailed video on changing a string. If you prefer diagrams and written instructions, we have that below.

Step One - Out with the Old

Remove all parts of the broken string. Be sure to find any little pieces which may have dropped to the bottom of your harp. If you are changing one of the a monofilament strings which is .036 gauge or less be sure to find the little anchor piece of leather too as you will need that for your new string.

Step Two - Find the Correct New String

All harp strings are custom made for each individual harp. Changing the diameter (gauge) or type of string to something other than what the luthier designed for your harp may invalidate your warranty or, worse yet, seriously damage your harp. In order to select the proper replacement string you need the string number and the Rees harp model.  To find the string number, count from the shortest string (#1) to the broken string.

If you already have a set of replacement strings pull out the proper number. If your replacement strings are notated by gauge use your string chart to make the proper selection. If you do not have the necessary string already you may order a full string set, a set of just the wrapped strings or only the string you need by going to our Shop. Once you have the correct string then go to Step Three, if your string is a monofilament, or Step Four if your are replacing either  a nylon/nylon wrapped string or a wire wrapped string.

Step Three - Tying a Harp Knot in a Monofilament Harp String

Take your monofilament string and thread it through the soundboard from the front (soundboard) side of the harp, run the string through the string hole of the soundboard, pushing it into the soundbox. From the back of the harp reach in through 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. Tie the knot as shown in the Harp Knot Diagrams (Steps A through G below). Be sure to use the extra piece of string or leather as shown in Steps F and G on strings .036 or smaller to prevent the knot from being pulled through the hole under string tension. After the knot has been tied, pull the string through and seat the knot firmly against the midrib. For additional assistance click on the Watch Video button below.

Tying a Harp Knot Step A - First Loop.

Tying a Harp Knot Step D - Pull the Second Loop Tight

Tying a Harp Knot Step G - Pull on the Long Part of the String to Tighten Both Loops as Far as They Will Go

Tying a Harp Knot Step B - Second Loop.

Tying a Harp Knot Step E - For Strings .036 Gauge and Below Make Sure There is Still Space in the First Loop (for larger strings skip to Step G)

Tying a Harp Knot Step C - Pass the Second Loop Over the First

Tying a Harp Knot Step F - For Strings .036 Gauge and Below Insert the Short Leather Anchor Piece into the First Loop

String knots should fit snugly without being pulled through the eyelet.

Step Four - Threading a Wrapped String

If your string is a wrapped string, either nylon-nylon or wire wrapped, the knot is already tied for you and all you have to do is thread it through the string hole from the inside out. For a nylon/nylon wrapped string be careful not to force it or pull it too quickly. Be gentle. If the thin nylon wrapping breaks the string is ruined. After the string is through the hole from the back, pull on it slowly but firmly from the front to "seat" the knot.

Step Five - Bring the String Up to the Tuning Pin

Now that the knot is seated against the midrib, grab the other end of the string and pull it all the way up to the tuning pin. If the string is of large diameter, you should cut the string with a knife (like a box knife) or at an angle so that a clean (non-flattened) end will fit through the hole of the tuning pin. Never cut a wrapped string on the wrapping because it will unwind and the string will be ruined. The only part that can be trimmed is the plain core that sticks out at the end. If the wrapping extends into the area you need to cut, you have the wrong string. Wrapped strings are ordered by their vibrating length (the distance between the soundboard and the bridge pin). When the string is made, the maker will add additional length to allow for the part that goes through the tuning pin and the additional wraps around.

Three or four wraps which drop straight to the bridge pin is correct.

Step Six - Thread the String Through the Tuning Pin

Important Note:  For a Rees Morgan Meadows, Morgan Meghan or our smaller double harps you will have zither (piano-style) tuning pins on your harp. (See Types of Pins for more information.) If your harp has piano style tuning pins it is very important that you turn the pin to which you will be attaching the new string counter clockwise about four turns before inserting the string into the hole. Zither pins have threads and if you do not back the pin out enough each time you replace a string, the pin may eventually screw too deep into the neck. Once this is done you can proceed.

Next, regardless of string or pin type, place the end of the string through the hole of the tuning pin so that about 1/4 inch of the string sticks out on the other side of the hole. Turn the tuning pin and wrap the string in the same direction as the neighboring pins. Try to line up the windings so that the string drops as straight as possible in line with the bridge.

The string should only wrap around the pin three or four times. Too many wraps means the string was cut too long and this will lead to a variety of problems. It is also important that you will have at least three wraps around the tuning pin when you are done. This will help distribute the stress on the string and help to prevent breakage.

Step Seven - Tune it Up!

Whew! All the hard work is done. Now bring the string up to pitch slowly. Turning too rapidly may break it. The new string will go out of tune quickly for awhile until it stretches and the knot tightens up. Be patient and remember that the more frequently you tune up that string, the more quickly it will settle in and hold for you.
