The guitar is a musical instrument composed of a wooden box with an acoustic whole on the center, six strings and a neck with frets. It is composed of a set of parts making its sound different from any other instrument. Below, we will give you details about its components. In this way, you will be able to distinguish them and choose the quality and type of the guitar that is most convenient for you.
Every guitar has a peg box, that is a set of tuning pegs. These mechanical parts increase or decrease string tension, thus providing the tuning wanted.
There are classic, perpendicular, safety and bass peg boxes.
Another essential part of a guitar is the barre, the string support point. There, the resonant features of the guitar body, box and neck are established. It can be made of several materials, such as elephant ivory, fossilized mammoth ivory, walrus ivory, bone, micarta, graphite, bronze, steel and plastic. There are also different types of barres. There are regular, block and Wilkinson barres.
Other component of the guitar is the fingerboard, a piece of wood or other synthetic material, placed on the neck and used to embed the frets. Since it is exposed to constant friction, it must me made of a very resistant material. There are different types of fingerboards. There are scalloped fingerboard, 16” radius fingerboard and compound radius fingerboard.
Frets are also essential parts of any guitar. There are pieces of metallic wire that divide the fingerboard into portions, defining the instrument sound. There are alpaca, nickel alloy and stainless steel frets. The purpose of the fret varies according to the material.
The bridge is another part composing classic and acoustic guitars. The bridge is, together with the barre, the string support point, so it is very important as regards the sound to get. It is a wooden basis where strings are placed. The strings are tied to the bridge through pivots. There is also a special bridge for electric guitars. There are fixed bridges, floating Steimberg bridges, floating Fender, floating Kahler and floating Floyd Rose.
Other component of the guitar is the shovel, the neck extension. Its purpose is to host the tuning pegs. Besides, it is aesthetically important, since it is used to identify the particular model used.
Strings are also very important, since its vibration defines the instrument sound. There are two types of strings: smooth strings, made of nylon or steel and wound strings, composed of a center of bronze, silver or nickel.
The neck is a wooden piece used to support the fingerboard and put the hand so that, besides supporting the peg box and the barre, the strings can be trodden by the fingers. There are different sizes and materials for necks. In acoustic guitars, C, D or V necks are used. The V ones are used for vintage guitars and C and D for more modern guitars.
Other main component of any guitar is the scale, the distance between the barre and the bridge saddle. It is very important for the instrument sound and performance comfort, since the longer the distance, the greater the string tension.
The body, both in classic and acoustic guitars, is very important. This is because a string vibrating suspended between two points does not produce enough volume to be heard. Thus, the body amplifies the sound through a resonance box, creating reflections projecting to the outside, causing different sound frequencies. The box is, in turn, divided into several parts: bridge, lid, rings and the bottom.
The pickups are magnets covered by a cupper thread coil. Within the electric guitar magnetic field, metallic objects, such as strings, vibrate, thus producing sound electric currents. There are different types of pickups. There are single coil, humbucking, active circuit and piezoelectric pickups. We should also take into account the resonant guitar and the steel pedal within this group.
