The Fascinating World of Guitars: Electric, Acoustic, and Classical Guitars
I. Overview of the Guitar Family
Introduce the status and characteristics of electric guitars, acoustic guitars, and classical guitars in the guitar family, as well as their respective unique charms.

Electric Guitar
Electric guitar is the product of modern science and technology and has a unique position in the guitar family. Its appearance is significantly different from that of traditional guitars. The body of the guitar is made of new hardwood and is equipped with devices such as volume and pitch adjusters and tremolo structures. The tone of an electric guitar is sharp, bright, and powerful, capable of producing a more aggressive sound. It is widely used in music styles such as rock, metal, and pop. Electric guitars need to be used in conjunction with electronic equipment. During performances, they need to be plugged into sound equipment to provide the best effect. They are suitable for large-scale performance occasions such as large concerts and rock concerts.

Acoustic Guitar
Acoustic guitars include classical guitars and folk guitars. Classical guitar is hailed as one of the world’s three major instruments on an equal footing with the piano and violin. It is the highest form of guitar art. It has a wide fingerboard and uses nylon strings. The sound quality is pure and thick. It is mainly used to play classical music pieces and has strict requirements for playing postures and techniques. Folk guitar is the most “civilian” member of the guitar family. It has a narrower fingerboard and uses steel strings. The sound is crisp and bright. It is mainly used for accompaniment and is suitable for music styles such as country, folk, and rock. It can be played in occasions such as small concerts and street performances.

II. The artistic charm of classical guitar

(1) Historical origin and development
Classical guitar first appeared in the 8th and 9th centuries. It originated from ancient Arab and Latin guitars. The academic community believes that it originated from the plucked instrument on the Iberian Peninsula in the Middle Ages. The evidence is the relief on the front of the Cathedral of Santiago de Compostela in the 12th century. By the 13th century, the Arab guitar was replaced by the lute, and the Latin guitar evolved into the vihuela. In the 15th century, the plucking style “vihuela” appeared. In the 16th century, direct finger plucking replaced plucking and became widely popular in Spain. At the same time, the lute also began to be popular. During the Renaissance, the popularity of the vihuela and lute reached its peak. In the 16th century, there were mainly two types of classical guitars with four and six strings in Spain. The four-string guitar was used to play popular songs and dances and folk songs, and the six-string guitar was used for performances by the royal family and nobles. In the 17th century, plucking was replaced by the baroque guitar with double strings. In the 18th century, the complex tuning of the four-string double-string guitar made the five-string single-string guitar more popular. In 1790, the tuning mode of EADGBE for the six-string guitar became the main mode. In the 19th century, metal tuning pegs and the popularity of romanticism made classical guitars gradually lose the market. Only a few composers created lyrical works. In the 20th century, pop music and jazz music had an impact on classical guitars, and new types of classical guitars appeared, such as the use of nylon strings and ten-string guitars. In the 21st century, electric guitars combined with technology are widely used, but classical guitars are still loved by classical music lovers with their unique artistic styles.

(2) Structure and tone characteristics
The appearance design of classical guitar is elegant and beautiful. The fingerboard is flat and slightly wide, and the sound box is thicker. It is equipped with three nylon strings and three metal-wound strings, which span across the sound box. There are 12 frets at the junction of the fingerboard and the sound box, and a total of 19 frets can be used. The sound hole is round and there is no baffle below. The front and back panels are flat. The tone of classical guitar is delicate and changeable, warm and soft, giving people a kind feeling. This is due to the characteristics of the wooden body and nylon strings. The tone is clear and bright, and every note can be clearly conveyed. When playing polyphonic pieces, the melody and harmony of each part can be clearly expressed. At the same time, it also has a large space for tone changes and can simulate the tone of percussion instruments.

(3) Performance forms and artistic connotations
Classical guitar can be played in various forms such as solo, ensemble, reprise, and concerto. In solo performance, it can fully show its delicate and changeable tone and rich expressiveness. In ensemble, reprise, and concerto, it can perfectly cooperate with other instruments to jointly perform beautiful music. Classical guitar represents the continuous development of music art and is the incarnation of inheriting and carrying forward music art. Its expressiveness even exceeds that of all other instruments. Beethoven, Brouwer and others have given very high evaluations to classical guitar. Therefore, classical guitar represents a higher level of art and requires the music literacy of the audience to be very high. Classical guitar is generally played in concert halls and is suitable for playing different styles of music such as classical music, flamenco, and jazz. It can freely interpret music of different periods and nationalities.

III. The modern vitality of electric guitar

(1) Basic music theory knowledge
The commonly used music theory knowledge of electric guitar can be divided into five major sections: intervals, scales, chords, rhythms, and fingerboards. An interval is the distance between two pitches. For example, a minor second is the smallest distance between two pitches. The pitch difference between E and F, B and C, etc. is only a semitone. A major second is the superposition of two minor seconds. For example, the distance between C and D is a whole tone. A major third is equal to a major second plus a major second. For example, the interval between C and E is a major third. A minor third is equal to a major second plus a minor second. For example, the interval between D and F is a minor third.
In terms of scales, natural scales are divided into natural major and natural minor. The natural major scale is 1234567. Taking C major as an example, its relative minor, A minor, is obtained by changing the cyclic order of the C major scale and taking A as the first scale “do”. The major pentatonic scale is obtained by removing 4 and 7 from the natural major scale. The minor pentatonic scale is obtained by removing 2 and b6 from the natural minor scale.
In terms of chords, they are composed of a group of sounds with a certain interval relationship. Taking the C natural major scale as an example, taking the seven pitches as the root notes respectively and looking for the third and fifth pitches upward will obtain their respective triads. For example, the third pitch of C(1) is E(3), and the fifth pitch is G(5). Thus, a C triad (135) is obtained.

(2) Basic skills and techniques
In terms of basic skills and techniques, first is finger function practice, aiming to make the fingers strong and independent. For example, some sentence exercises in the first, second, and fifth volumes of “Hell Training” can be carried out. To strengthen the ring finger and little finger, exercises that use only fingers 3 and 4 can be used. In terms of strengthening right-hand plucking, Paul Gilbert’s right-hand alternate plucking exercises can be carried out. With left-hand muting and right-hand pure alternate plucking, the number can be decreased from 16 times, 8 times, and 4 times to 3, 2, and 1 times as needed. Pay attention to right-hand volume dynamic control and focus on movement details when practicing slowly. Paul Gilbert’s right-hand upstroke exercises can also be carried out. With left-hand muting and right-hand pure upstroke exercises, combined with right-hand upstroke exercises with triplets, it forms a set of exercises.
Nerve training is mainly to solve the problem of incoordination between the left and right hands. For example, tremolo plucking exercises can be done. Keep the right hand plucking alternately while the left hand plays tremolo. The fingerings are: 1212121212; 1313131313; 1414141414; 232323232; 242424242; 34343434. John Petrucci’s exercises for coordination are also very effective.
Basic skill technique training covers the most commonly used techniques. For example, different pickup combinations can produce different tones. Single-pickup electric guitars are suitable for playing crisp and bright tones and are often used in rock and pop music. Dual-pickup electric guitars can choose different pickup combinations to obtain specific tone effects. Triple-single-pickup electric guitars can adjust tone and output mode through switches for each pickup.

(3) Classification and characteristics
Electric guitars can be divided into hollow-body electric guitars, semi-hollow-body electric guitars, and solid-body electric guitars according to their body structure and sound characteristics. Hollow-body electric guitars usually have jazz and blues as their main styles because they can produce warm and soft sounds and are suitable for playing music similar to these styles. Among them, Gibson’s Les Paul and ES-335 series hollow-body electric guitars are the most representative. Semi-hollow-body electric guitars are between hollow-body electric guitars and solid-body electric guitars. They have more complex and diverse tones and ranges and are suitable for playing more styles of music, including pop, rock, blues, etc. Famous semi-hollow-body electric guitar brands include Gibson’s ES-335 and Lucille series, as well as Sergei’s Platinum and Rooster. Solid-body electric guitars are currently the most common type of electric guitar. Their bodies are completely made of solid wood or other sturdy materials. They usually have a longer sustain time and higher volume and are suitable for playing music styles such as rock and heavy metal. The most famous solid-body electric guitar brands include Fender’s Stratocaster and Telecaster, as well as Gibson’s Les Paul.
Electric guitars can produce various tones through effect pedals and have very strong expressiveness. For example, a distortion pedal can make the sound of an electric guitar hoarse and is often used in the prelude, interlude, coda, or cadenza of rock music. An overdrive pedal is often used in the lead melody, prelude, interlude, and coda of electric guitar and can produce a passionate heavy metal tone. A compressor provides undistorted and bright tones and can extend or shorten the duration of notes. A chorus pedal can make the sound of an electric guitar sway back and forth, producing a soft, broad, and grand chorus effect. A delay pedal can produce echoes, making the sound rich, full, and with a sense of space. A phaser can make the sound vibrate, with an elegant effect. A wah pedal can produce a “wah~woo” sound and can be used to play humorous and lively music. An equalizer can adjust the frequency response curve of an electric guitar and set the tone state of an electric guitar.

IV. The natural beauty of acoustic guitar

(1) Sound propagation characteristics
The sound of an acoustic guitar does not only come out from the sound hole. When the panel is activated by the vibration of the strings, it vibrates the air both inside and outside the guitar at the same time, and the sound is also propagated through the vibration of the panel. Anyone who has used a sound hole plug to prevent feedback from the pickup can experience that even if the sound hole of the acoustic guitar is blocked, the acoustic guitar still makes a loud sound. Most people also agree that when the blockage of the sound hole is removed, the sound of the guitar sounds better. This is because the existence of the sound hole allows the sound to be transmitted more concentratedly, enhancing the directionality and volume of the sound.

(2) The influence of cracks on sound
Cracks on the panel, back, and sides of a guitar have little influence on tone and volume as long as they do not affect structures such as the bracing. In reality, many people are afraid that any cracking anywhere on the guitar will damage the sound. But in fact, unless the crack causes the bracing to loosen or other structural defects, multiple cracks on the guitar panel will not damage the sound at all. Although cracks on the back and sides should also be repaired to prevent them from continuing to expand, they have even less influence on tone or volume. However, cracks will damage the value of the guitar. For example, if some precious guitars have cracks, their collection value and market price may drop significantly.

(3) Neck state and adjustment
The neck of a guitar does not always have to be kept straight. Most guitarists find that when their necks have a slight “relaxation” (bending forward), their string noise will be less and the tension will be more comfortable, especially when playing the bass strings forcefully in the lower positions. But this requires guitarists to master reasonable adjustment methods, because if adjusted improperly, it may lead to problems such as poor tone and inaccurate pitch. When adjusting the neck, special attention should be paid to making the adjustment range small each time. Adjustments can be made little by little. To test the neck state, press the strings on the first fret of the 6th string and the last fret of the 6th string. Judge the state of the neck by observing the distance between the 8th fret post and the string.

(4) Types, advantages and disadvantages of pickups.
- Piezoelectric pickup: Piezoelectric pickups are basically active pickups and need to be powered by batteries to be used. The advantages are that the output power is large and the sound is relatively balanced. Generally, it is more suitable for singing and playing. Many guitars are equipped with piezoelectric pickups when they leave the factory. The disadvantage is that a single piezoelectric pickup generally has a relatively strong electronic taste. Common brands include Fishman, LR Baggs, etc.
- Sound hole pickup: A sound hole pickup refers to a pickup that is clamped on the sound hole of a guitar. It is divided into active pickups and passive pickups. Active pickups need to be powered by batteries to be used. Passive pickups do not need to be powered by batteries, but need an external preamplifier to boost the volume to be used. The advantages are that the sound is thick, clean and powerful, and the output power is large. The disadvantage is that only the sound of string vibration can be received, and the vibration of the guitar body cannot be received (can’t slap the guitar). The restoration degree of the guitar’s own tone is not enough, and there is occasionally an iron wire taste.
- Microphone pickup: As the name suggests, it is a pickup that uses a microphone to pick up sound. The advantage is that it has a good restoration degree of the guitar’s own tone and can receive slapping sounds. The disadvantage is that generally speaking, the microphone pickup is placed inside the guitar body, so it is very prone to feedback. The output power is relatively small, and the quality requirements for the microphone itself are relatively high.
- Pickup patch: A pickup patch refers to a pickup that is pasted inside the panel of the guitar body. It is mainly used to pick up the sound of panel vibration and is basically a passive pickup. The advantages are that the sound is clean, the feedback on details is also relatively good, and a strong slapping sound can be received. The disadvantage is that the installation is relatively troublesome, and the requirements for the installation position are extremely high. Different people may install it with completely different tones.
In various music styles, common pickup combinations are:
For singing and playing: piezoelectric + microphone/sound hole + microphone.
American fingerstyle: piezoelectric + microphone (traditional); percussive American style: sound hole + pickup patch/sound hole + microphone/sound hole + microphone + pickup patch.
Japanese fingerstyle: sound hole + pickup patch.
In these pickup combinations, in actual use, one pickup needs to be used as the main output function, and the remaining pickups are used to supplement the deficiencies of the main output pickup. For example, in the combination of piezoelectric + microphone, usually the piezoelectric pickup is used as the main output pickup. The microphone pickup can just neutralize some of the electronic taste to make the sound more restored and can also receive the slapping sound. Another example is the combination of sound hole + pickup patch commonly used in Japanese fingerstyle. Usually, the sound hole pickup is used as the main output pickup, and the pickup patch is used to neutralize some of the deficiencies of the sound hole pickup, such as not being able to receive the slapping sound and having an iron wire taste in the sound.
