Unlike other types of stringed instruments, such as violins and violas, harps are played without the use of bows. The strings on a harp are designed to be plucked or grazed with the fingertips. There are several different types of strings for the wide variety of harps available. Manufacturers produce harp strings from different materials, including nylon and copper; they are available in lengths designed to fit various types of harps.
Wire-strung harps are strung with wires constructed from a variety of metals. Copper, brass, and bronze are a few of the more popular metals used in the construction of harp strings. Even certain precious metals such as silver are manufactured into harp strings. Metal strings are not nearly as flexible as nylon strings, but they are more durable and last longer.
Monofilament nylon harp strings are typically available in a limited range of colors including red, black, and blue. Nylon strings are the ideal strings for most types of harps. They are flexible, relatively easy to install, and traditionally cheaper than metal strings.
The strings on a harp must be positioned a minimum distance apart to allow ease of use and to prevent them fromtouching one another. Positioning strings too close together may also promote excessive vibration, resulting in a buzzing sound. While smaller harps are usually designed for use with just one type of string, larger models are often fitted with several different types of strings to achieve a certain range of sounds.
Lever harps employ a lever system that increases their range, adding the ability to play flat and sharp notes. Attached to a lever, a string can be used to produce two different notes. A switched lever shortens the effective length of each string, allowing a different pitch to be produced when plucked. These harps offer the benefit of producing a broader range of sounds from a limited number of strings.
Pedal harps feature pedal systems instead of levers to achieve different sounds from strings. These harps typically include seven pedals that each operate in one of three adjustable positions. Pedals moved into their middle positions do not affect the notes produced by a string, but pedals in their topmost positions produce flat notes and pedals in their lowest positions, producing sharp notes. This type of harp offers the benefit of not requiring the user to employ his or her hands to produce a flat or sharp note, but the added mechanical components required of these harps makes them much bulkier and heavier than most lever harps.
Irish harps are traditionally wire-strung harps that employ metal strings. The term “Celtic harp,” however, refers to any harp that grew out of the Celtic tradition. These harps are traditionally lever-type harps that use nylon, wire, or gut strings. Double-strung harps, meanwhile, are generally designed for use with nylon strings.
Frequently Asked Questions
What are the main types of strings used on harps?
Harps typically use three main types of strings: gut, nylon, and wire. Gut strings, made from the intestines of sheep or other animals, offer a warm, rich tone and are commonly used on classical harps. Nylon strings, a modern alternative to gut, provide durability and a bright sound, making them popular for both classical and folk harps. Wire strings, usually made of steel, bronze, or copper, produce a clear, bell-like tone and are often found on historical and folk harps.
How do the different harp strings affect the instrument's sound?
The material of harp strings significantly influences the instrument's sound. Gut strings produce a warm, nuanced tone that is highly responsive to the player's touch. Nylon strings offer a brighter, more consistent sound and are less sensitive to changes in humidity and temperature. Wire strings, with their metallic composition, create a resonant, ringing sound that sustains longer than gut or nylon. The choice of string type can tailor the harp's sound for specific musical styles and player preferences.
Can you mix different types of harp strings on the same instrument?
Yes, it is possible to mix different types of harp strings on the same instrument, and harpists often do so to achieve a desired blend of tones. For example, a harpist might use gut strings in the middle octaves for warmth, nylon in the higher octaves for brightness, and wire in the bass for a robust foundation. However, it's important to consult with a professional harp technician to ensure the harp's construction can handle the tension differences between string types.
How often should harp strings be replaced?
The frequency of replacing harp strings depends on several factors, including the type of strings, the amount of playing, and environmental conditions. Gut strings may need to be replaced every 1-2 years, while nylon and wire strings can last longer. Regularly played strings or those exposed to fluctuating humidity and temperature may require more frequent changes. Harpists should monitor their strings for signs of wear, such as fraying or loss of tonal quality, to determine when replacement is necessary.
Are there any innovative materials being used for harp strings?
In recent years, advancements in materials science have led to the development of synthetic alternatives to traditional harp strings. For instance, fluorocarbon strings, which are denser and more durable than nylon, offer a bright sound with increased projection. Composite materials are also being explored for their potential to combine the best qualities of gut and synthetic strings. These innovations aim to enhance the harp's sound while providing greater stability and longevity.
