- Personalized Maintenance: You can choose the exact strings you prefer and ensure they are installed to your specific standards.
Understanding Harp String Types
Before you even think about replacing a string, you need to understand the different types and how to identify the correct replacement. Harps utilize a variety of string materials, each with unique tonal qualities and tension characteristics.
Gut Strings
Traditionally made from sheep or cattle intestines, gut strings are renowned for their warm, rich, and complex tone. They are typically found in the mid-range of pedal and lever harps. Gut strings are sensitive to humidity and temperature changes and require more frequent tuning.
Nylon Strings
Often used in the upper registers of harps, nylon strings offer a bright, clear sound and are more stable than gut strings. They are also more affordable and durable, making them a popular choice for student harps and those in humid climates.
Nylon/Synthetic Core Strings (e.g., Savarez Alliance, Bow Brand Pedal Gut)
These strings combine a synthetic core (often nylon or a similar material) with a wrapping, usually of nylon or a synthetic fiber. They aim to mimic the sound of gut strings while offering greater stability and durability. They are a popular choice for both pedal and lever harps, bridging the gap between traditional gut and modern nylon.
Wire/Wound Strings
Found in the bass registers of most harps, wire strings consist of a steel or synthetic core wrapped with a metal wire (often copper, silver-plated copper, or brass). These strings produce a deep, resonant tone and provide the necessary tension for the lower notes. They are less prone to breaking than gut or nylon but can be more challenging to install due to their stiffness.
Identifying the Correct Replacement String
The most critical step is ensuring you have the correct replacement string. Harps are designed with specific string gauges and materials for each note. Using the wrong string can negatively impact the sound, intonation, and even damage your harp.
- Consult Your Harp's String Chart: Most harp manufacturers provide a string chart, often found in the harp's case or on their website. This chart lists the specific string type, gauge, and length for each note.
- Examine the Broken String: If possible, compare the broken string to the new one. Note its color, material, and thickness.
- Measure the String Length: While most strings are sold in standard lengths, it's good practice to have an idea of the required length, especially for custom harps.
- Consider the Brand: While not always strictly necessary, using strings from the same manufacturer as your existing set can help maintain tonal consistency.

Step-by-Step Guide to Replacing a Harp String
This guide covers the general process. Specific harps may have slight variations, so always refer to your harp's manual if available.
1. Prepare Your Workspace
- Stability: Place your harp on a stable, level surface. If it's a pedal harp, ensure the pedals are locked or in a neutral position. For lever harps, ensure all levers are disengaged.
- Protection: Lay a soft cloth or blanket underneath the harp to protect the floor and the harp's finish.
- Lighting: Ensure you have good lighting, especially if you need to look inside the soundbox.
- Gather Tools: Have all your recommended supplies within easy reach.
2. Remove the Broken String (If Present)
- Locate the Knot: For gut, nylon, and synthetic core strings, the string is typically knotted inside the soundbox, passing through a hole in the soundboard and then over a bridge pin. For wire strings, they are usually secured to a hitch pin on the soundboard.
- Access the Soundbox: If your harp has a removable soundbox cover, open it. For harps without a removable cover, you'll need to reach through the sound holes.
- Untie/Unwind:
- For Gut/Nylon/Synthetic: Carefully untie the knot inside the soundbox. Sometimes the knot is tight; use needle-nose pliers if needed, but be gentle. Once untied, pull the string out from the tuning pin end.
- For Wire Strings: Wire strings are usually secured to a hitch pin with a loop. Carefully unhook the loop from the hitch pin.
- Unwind from Tuning Pin: Once the string is free from the soundboard, unwind it from the tuning pin.
- Inspect for Damage: Briefly check the string hole and tuning pin for any burrs or damage that might have caused the string to break. Smooth any rough edges if possible with fine sandpaper, but be extremely careful not to damage the wood.
3. Prepare the New String
- Identify Ends: For gut, nylon, and synthetic strings, one end is usually thicker or has a pre-tied knot. This is the end that goes inside the soundbox. For wire strings, one end will have a pre-formed loop.
- Create the Knot (for Gut/Nylon/Synthetic):
- Single Knot: For smaller gauge strings, a simple overhand knot followed by a double overhand knot (creating a figure-eight style knot) is often sufficient. Ensure the knot is tight and secure.
- Triple Knot/Harp Knot: For larger gauge strings, a triple knot or a specialized "harp knot" (which involves wrapping the string around itself multiple times before tightening) provides more security and prevents slippage. There are many video tutorials available for tying a proper harp knot. Practice on a spare piece of string first.
- Ensure Knot is Large Enough: The knot must be large enough not to pull through the string hole in the soundboard.
4. Threading the New String
- From Inside the Soundbox:
- Take the knotted end (or looped end for wire strings) and, reaching inside the soundbox, feed it through the correct string hole in the soundboard.
- This is where the stringing hook comes in handy. Insert the hook from the outside of the soundboard into the string hole, catch the string end, and pull it through.
- Over the Bridge Pin: Once the string is through the soundboard, guide it over the corresponding bridge pin (the small pin on the soundboard that the string rests on). Ensure it sits securely in the groove of the pin.
- Up to the Neck: Guide the string up the neck of the harp, ensuring it passes over the correct bridge saddle (if applicable) and through any guide holes or slots on the neck.
- Through the Tuning Pin Hole: Feed the string through the hole in the tuning pin. The string should pass through the hole from the side closest to the soundboard.
5. Winding the String onto the Tuning Pin
This step is crucial for string stability and preventing slippage.
- Initial Wind: Pull the string taut, leaving about 2-3 inches of excess string beyond the tuning pin. Make a sharp bend in the string where it exits the tuning pin hole.
- First Wrap: Begin winding the tuning pin counter-clockwise (for most harps). Ensure the first wrap goes OVER the short end of the string, effectively pinching it against the tuning pin. This helps lock the string in place.
- Subsequent Wraps: Continue winding, making sure each subsequent wrap goes UNDER the previous one, moving downwards towards the base of the tuning pin. This creates a neat, conical coil that maximizes friction and stability. Aim for 3-5 neat wraps.
- Maintain Tension: Keep a slight tension on the string as you wind to prevent slack.
- Trim Excess: Once you have enough wraps, use wire cutters to trim any excess string from the short end, leaving a small stub (about 1/4 inch) to prevent unraveling. Be careful not to cut the main string.
6. Initial Tuning and Stretching
- Gentle Tuning: Using your electronic tuner, slowly bring the string up to pitch. Do not rush this process, especially with new strings, as they are prone to breaking if brought up to tension too quickly.
- Stretching: New strings, especially gut and nylon, will stretch considerably. Once the string is at approximate pitch, gently pull on it several times along its length (away from the soundboard). You'll hear the pitch drop. Retune. Repeat this stretching and tuning process several times until the string holds its pitch more consistently.
- Check for Buzzes: Pluck the string and listen for any buzzing. Ensure it's seated correctly on the bridge pin and tuning pin.
7. Final Adjustments and Break-in Period
- Fine Tuning: After several hours or a day, the string will likely have stretched further. Re-tune accurately using your electronic tuner.
- Lever/Pedal Adjustment (if applicable): If you replaced a string on a lever or pedal harp, engage the lever/pedal and check the pitch. New strings can sometimes affect the intonation of the lever/pedal mechanism. Minor adjustments to the lever/pedal fork might be necessary, but this is often best left to a professional if you're unsure.
- Playing In: Play the new string regularly. This helps it settle and achieve its true tonal quality. It may take several days or even weeks for a new string to fully stabilize.
