We can divide them into two basic groups: Nylon and metal.

Nylon - It belongs exclusively to the classic (Spanish) or flamenco guitar. The three lower melodic strings are made of special nylon fiber. Three bass strings are made of several nylon fibers that are wrapped with different types of metal wire. The properties of melodic strings without winding improve with age - the nylon is strengthened under tension and the strings therefore get brighter sound and more loudness. They are very stable and hold well.

Depending on their hardness, we divide them into soft, medium and hard.

Nylon strings with low, medium, high and extra-thick thickness are sold. Some nylon strings are tailored to the special sound effect we want to achieve. They can have, for example, enhanced "heights" to highlight high tones or "bass" to highlight deep tones. The special category includes flamenco strings, which are characterized by lower tension and a characteristic creeping effect.

I do not recommend puting metal strings on the Spanish guitar. I understand this with older types of guitars (Czech Cremons), which can not be categorically included in Spanish or jumbo guitars. These guitars were often designed for metal strings and also sold with them (at least if I know, possibly correct me if I'm wrong). If you are still decided to do this (often the reason is to achieve a more pronounced and more pronounced sound, which can be achieved partly by the knowledge of the correct keystroke on strings), do not use strings with a diameter "e" of a string higher than 0.10 ("dozens"), otherwise it is very likely that you will begin to kick off the bridge and bend your neck and destroy the guitar!!!

Metal - Generally we distinguish according to the diameter of the "e" (lower) strings:


0.08 - electric guitars (do not use for acoustic guitar!)

0.09 and 0.10 - soft, easy to squeeze, but they do not have too much sound

1.1 and 1.2 - harder, but the sound is stronger, better

In general, the harder the strings you choose, the higher the sound quality (if the strings are good), but also the more difficult strings to squeeze.


Firstly, it depends on the type of your guitar:

Spanish guitar - Nylon strings (may be metallic, but Ido not recommend for the above reasons ). Nylon strings do not matter so much on hardness (all are relatively easy to press), like the style of play that we prefer. We are therefore mainly guided by the sound effects that strings offer - see Nylon strings.

Different guitars may suit different types of strings, and it is not possible to tell with precision which strings will fit the one or the guitar. So often we have nothing left to do but to follow the "trial-error" method first and try out all the strings until we find the ones that suit us.

According to the musical activity I want to apply - nylon strings are used mainly in classical music, flamenco, brazilian music and jazz.

Jumbo Guitar - Metal Strings. Here depends mainly on the diameter (hardness) of the strings, see the Metal Strings and, of course, the style of the game - if you play jazz, for example, you may need a sharper and more pronounced tone and choose harder strings. It also depends on whether you are playing your fingers (rather soft strings) or tricks (they may be harder). For beginners I recommend soft strings of 0.10 or 0.11.

Electric guitar - The surface of the electric guitar strings is made of nickel and iron alloy, nickel-plated steel, stainless steel and other metals or alloys. Different materials used on the surface of the string provide a different tone and also a slightly different level of output when amplified.

How to put strings on a guitar

Before we will put the strings on the guitar, it is important to remove dirt that could quickly degrade the strings. If we decide to make some adjustments or fixes on a guitar, it is advisable to do so before pulling new strings so that we do not have to repeatedly take them off and put them to degrade them. Replace the strings with your hands! For the description of guitar care, please refer to the Guitar Care section.

Nylon strings - see instructional video.

Some types of nylon have a few centimeters of loose wires at one end. This end does not belong to the bridge!!!

What will we need?

Splitting pliers, string reel and tuning.

None of these utilities is a necessity, but it can make it easier for us to work, depending on the situation. I will try to explain why:

Splitting Pliers - Used to shorten the string if it is too long. Also, after the exchange, we can pinch the possible protruding ends of strings in bridges that touch the front plate and cause unpleasant "buzzing" at play. Especially for metal strings it is advisable to pinch the protruding ends at the heads of the guitar. We avoid the painful insertion of the string into your finger or eye!

String Reel - Allows strings to wind evenly and quickly.

Tuner - Some good-hearted guitarists already remember the pitch of the strings and without the tuning (but they must have silence, which is also not always possible). Then it is also possible to use the other tuned tool to tune in. The tuner may not always be 100% reliable (may be poor or poorly tuned due to faulty batteries). For more information, see  Tuning Guitar and Guitar Tuners.
