Ask the Expert: What’s the Deal with Nylon Guitar Strings? Mr. Jayson Martinez, M.Mus; M. EdLd. NJMEA Chairperson for Guitar Education
Thanks, Martin Keith, for your valuable insights! Martin Keith is a luthier, repair and restoration expert, and working musician based in Woodstock, New York. martinkeithguitars.com Q: I’ve been a steel-string player for years, but just got my first nylon-string guitar. I want to figure out what strings will work best for me, but the names and tensions are confusing. Can you help clarify things?—Rebecca P., via email A: Thanks for the question! Rest assured—you are not alone. Players who come from the steel-string world are accustomed to the relatively simple system of numbered gauges (12s, 13s, etc.) standard among manufacturers. By comparison, the naming convention for nylon-string sets is a bit more poetic, and not quite as easily portable from one brand to another. The weights of string sets are usually indicated with terms such as medium hard, hard, and extra hard. To add to the confusion, many of these sets overlap in unpredictable ways—for example, La Bella’s upscale Argento line includes the same second- and third-string gauges in all three available weights. Nylon-string sets also have wider variation in materials than steel strings, in all three main areas of construction: the core, the wrap, and the plain string. Let’s take a quick look at the differences available for each, along with some useful terminology. Unlike steel strings, nylon sets usually have three wound strings (known as basses) and three plain strings (called trebles). The basses are wound with a metal wrap wire over a stranded filament core, made from either nylon or a blend of other synthetic fibers (such as in D’Addario’s Pro-Arté Dynacore line). The alloys used for the wraps vary and can have a big impact on the tone and response of the string. String manufacturers use wrap alloys ranging from traditional 80/20 bronze to more exotic choices, even pure silver in the case of La Bella’s Argentos. TEMPO
At the dawn of the modern era of guitar, the only choice for treble strings was gut, usually sheep intestine. As an organic material, gut presents some difficulties—it will react to heat and humidity, causing tuning instability. During World War II, the supply of natural gut was restricted, as it was also the preferred material for medical sutures. In response to this shortage, the Augustine string company, in collaboration with E. & O. Mari/La Bella and with input from classical guitar legend Andrés Segovia, developed nylon trebles and formally introduced them to the market in 1948. Other makers soon followed, and the stability and predictability of nylon soon made it the material of choice. Because of the inherent properties of nylon—and the processes used in its manufacture—the shape and diameter of clear nylon strings is not always perfect. There can be tiny variations along the length of a string, which are too small to notice, but just enough to affect the string response, particularly the intonation. To address this, string makers developed rectified strings, which begin as clear nylon and are then ground to precise shapes and sizes. The resulting strings hold closer tolerances for dimensions along their length, which improves intonation and consistency. However, the grinding process leaves a textured surface on the string, quite different in feel from the slick, smooth feeling of clear nylon. Some players experience more string squeak and noise with rectified strings. They are also generally felt to be a bit warmersounding than clear nylon trebles. Black nylon trebles are most often seen on older folk nylon guitars and are typically associated with a softer, warmer tone and less clarity and articulation. The lower tension of these strings is also a good fit for beginning players or those with less hand strength. These strings are usually equipped with ball ends, which simplify stringing vs. the traditional knot-style bridge attachment. In recent years, carbon and other composites have entered the market. Carbon compositions are denser, and therefore a thin carbon string will have equivalent mass to a 38
