At present, although there are 610 kinds of nylon strings, almost all the strings used in classical guitar are colorless and transparent, and the tensile strength is about 36 kilograms of nylon strings with L square millimeter. Other colored strings (such as black, etc.) are mostly dyed or other pigments, so they are easy to wear. Tenor strings are strings of a certain thickness drawn from melted raw materials. Bass strings are made up of dozens of fine nylon hairlike strands, and a circle of metal wires with steel as the main material is attached to the periphery. This kind of nylon string actually has many advantages, but also many disadvantages. Here, how to make the ideal strings is introduced. The ideal guitar string requires three conditions:
(1) The material and roughness of the vibrating part of the string should be uniform, and the section of the string should be circular. This is to get the correct interval.
(2) Appropriate softness and elasticity are required. Make the vibrating sound of the string produce a good timbre (like the third string, which is slightly lack of softness, the timbre will easily become dull).
(3) Appropriate gravity and tension (flexibility). Chord length and pitch (both the vibrator and the thickness of the chord are critical). At the same time, it also has something to do with the volume. Generally speaking, if the larger strings are tightened, the vibration force of the strings will increase and the volume will also increase.
Method of identifying strings:
High-pitched strings should have good transparency, rubbing with the fingers should have a very round feeling, while using the fingers to pass through the whole string without bumping phenomenon. The silver-plated color of the bass string should be glossy, and the elasticity of the whole string should be average. Imported high-quality strings on the market include Augustine, La Bella, D’Addario, SAVAREZ and Constantist in the United States, and Japanese strings are also made of imported materials, but the bass strings with poor silver plating lack durability. French nylon strings are soft, so there are many asymmetrical phenomena in the amplitude of the whole string. On the contrary, the quality of the bass strings is good, but the volume of the bass strings is very good. There are fewer asymmetrical phenomena in the soft and hard size of the American tenor strings than in France, and the durability of the bass strings is better because they are hard.
A set of imported nylon strings costs from tens to hundreds of yuan. Most foreign guitarists change one set in a week or so (especially bass strings with silver plating have no luster, lack of music color). If the economic conditions are limited, the following methods can be used to extend the service life of the string as far as possible: the tenor string moves slightly in the place of the piano code every week; the bass string should be replaced once a week (with two sets of strings, alternately used), the replaced string should be washed with neutral detergent, and after natural drying, the sound quality close to the new product can be restored. But this exchange can only be limited to about two times (because of the natural consumption of the string’s flexibility and the aging of the outer metal coils, which can not be used).
