The classical guitar — (sometimes called the "Spanish guitar" or "nylon string guitar") — is a 6-stringed plucked string instrument from the family of instruments called chordophones. The classical guitar is well known for its comprehensive right hand technique, which allows the soloist to perform complex melodic and polyphonic material, in much the same manner as the piano.
The classical guitar is characterized by:
The name classical guitar does not mean that only classical repertoire is performed on it, although classical music is a part of the instrument's core repertoire (due to the guitar's long history); instead all kinds of music (folk, jazz, flamenco, etc.) are performed on it.
The term modern classical guitar is sometimes used to distinguish the classical guitar from older forms of guitar, which are in their broadest sense also called classical, or more descriptively: early guitars. Examples of early guitars include the 6-string early romantic guitar (ca. 1790 - 1880), and the earlier baroque guitars with 5 courses.
Today's modern classical guitar is regarded as having been established from the late designs of the nineteenth century Spanish luthier Antonio Torres Jurado. Hence the modern classical guitar is sometimes called the "Spanish guitar".
The classical guitar has a long history and one is able to distinguish various:
Both instrument and repertoire can be viewed from a combination of various contexts:
Brief examples using the above classifications (historical, cultural/stylistic, social etc.), to show the colourful diversity of the classical guitar:
Interpreting works of a specific composer in a specific style requires an understanding of the historical cultural/stylistic and social aspects/influences, considering music an expressive art. This is often called the study of performance practice, with attempts at historically informed performance (sometimes abbreviated HIP).
The classical guitar as an instrument today has access to repertoire that spans numerous chronological periods:
While "classical guitar" is today mainly associated with the modern classical guitar design, there is an increasing interest in early guitars; and understanding the link between historical repertoire and the particular period guitar that was originally used to perform this repertoire.
Different types of guitars have different sound aesthetics, e.g. different colour-spectrum characteristics (the way the sound energy is spread in the fundamental frequency and the overtones), different response, etc. These differences are due to differences in construction, for example modern Spanish guitars usually use a different bracing (fan-bracing), than was used in earlier guitars (they had ladder-bracing); and a different voicing was used by the luthier. See Classical guitar making for more information.
It is interesting to note the historical parallel between musical styles (baroque, classical, romantic, Spanish nationalist, flamenco, jazz) and the style of "sound aesthetic" of the musical instruments used, for example: Robert de Visée played on a baroque guitar with a very different sound aesthetic than the guitars used by Mauro Giuliani and Legnani - they used 19th century guitars. These guitars in turn sound different from the Spanish models used by Segovia, that are suited for interpretations of romantic-modern works such as Torroba.
When considering the guitar from a historical perspective, the musical instrument used is just as important as the musical language and style of the particular period. As an example: It is impossible to play a historically informed de Visee or Corbetta (baroque guitarist-composers) on a modern classical guitar. The reason is that the baroque guitar used chords, which are two strings close together (in unision), that are plucked together. This gives baroque guitars an unmistakable sound characteristic and tonal texture that is an integral part of an interpretation. Additionally the sound aesthetic of the baroque guitar (with its strong overtone presence) is very different from modern Spanish-type guitars, as is shown below.
Today's overuse of Torres and post-Torres type Spanish guitars for repertoire of all periods is somewhat critically viewed: Torres and post-Torres style modern guitars (with their fan-bracing and design) have a thick and strong tone, very suitable for Spanish and modern-era repertoire. However they are considered too saturated in fundamental (opposed to overtone partials) to be appropriate for earlier repertoire (Classical/Romantic: Carulli, Sor, Giuliani, Mertz, ...; Baroque: de Visee, ...; etc.). "Andres Segovia presented the Spanish guitar as a versatile model for all playing styles"[8], to the extent, that still today, "many guitarists have tunnel-vision of the world of the guitar, coming from the modern Segovia tradition"[9].
Interestingly, while fan-braced Spanish (Torres, post-Torres style) instruments coexisted with traditional central European ladder-braced (19th century style) guitars at the beginning of the 20th century; the central European guitars eventually fell away. Some attribute this to the popularity of Segovia, considering him "the catalyst for change toward the Spanish design and the so-called 'modern' school in the 1920's and beyond"[8]. The styles of music performed on ladder-braced guitars were becoming more and more unfashionable; and e.g. in Germany musicians were in part turning towards folkstyle music (Schrammel-music and the Contraguitar), but this only remained localized in Germany and Austria and was quickly unfashionable again, etc. On the other hand, Segovia was concertizing around the world, popularizing his Spanish guitar, as well as a new style of music in the 1920s: Spanish romantic-modern style, with guitar works by Torroba, de Falla, etc. Some people consider it to have been this influence of Segovia, which eventually led to the domination of the Spanish instrument - factories all over the world began producing them in large numbers.
As was explained above, the classical guitar as an instrument today has access to repertoire that spans numerous style periods. This section attempts to provide an overview of some of these periods, their composers; and the guitars that were used in the particular period.
Composers of the Renaissance period include Luis de Milán and Alonso Mudarra.
Vihuela, Four course guitar
Composers of French baroque include Robert de Visée and Francesco Corbetta. In Spain Gaspar Sanz was active.
During the period from approximately 1780 to 1850 the guitar was an extremely popular instrument with numerous composers and performers such as
There is even an image from 1825 by Charles de Marescot entitled "La Guitaromanie".
In the 20th century numerous different styles of music (using a classical guitar) emerged:
At the beginning of the 20th century (esp in the 1920s) Andrés Segovia began to popularize the modern Spanish classical guitar with a particular style of romantic-modern and neo-romantic works which were composed by Federico Moreno Torroba, Manuel Ponce, Mario Castelnuovo-Tedesco, Alexandre Tansman and often dedicated to Segovia. This music can be called Segovia-repertoire, since it would not exist without Segovia.
In the middle of the century Luiz Bonfá popularized Brazilian musical styles such as the newly created Bossa Nova, which was successfully received by audiences in the USA.
The evolution of the classical guitar and its repertoire spans more than four centuries. It has a history that was shaped by contributions from earlier instruments, such as the Lute, the vihuela, and the baroque guitar. The popularity of the classical guitar has been sustained over the years by many great players, arrangers, and composers. A very short list might include, Gaspar Sanz (1640–1710), Fernando Sor (1778–1839), Mauro Giuliani (1781–1829), Francisco Tárrega (1852–1909), Agustín Barrios Mangoré (1888–1944), Andrés Segovia (1893–1987), Alirio Diaz (1923), Presti-Lagoya Duo (active from 1955-1967: Ida Presti, Alexandre Lagoya), Julian Bream (1933), and John Williams (1941).
The last guitarist to follow in Segovia´s footsteps was Julian Bream and Julian Bream will be 73 years old on July 15th 2006. Miguel Llobet, Andres Segovia and Julian Bream are the three performer personalities of the 20th century. Do not understand me wrong, we have many guitarists today that are very excellent performers, but none with such a distinct personality in their tone and style as Llobet, Segovia and Bream. In all instrumental areas, not just the guitar, there is a lack of individualism with a strong tendency to conformity. This I find very unfortunate since art (music, theatre or the pictorial arts) is a very individual and personal matter.[13]—Bernard Hebb, Interview
Throughout the centuries, the classical guitar has evolved principally from three sources: the lute, the vihuela, and the Renaissance guitars.
Instruments similar to what we know as the guitar have been popular for at least 5,000 years. The ancestry of the modern guitar appears to trace back through many instruments and thousands of years to ancient central Asia. Guitar like instruments appear in ancient carvings and statues recovered from the old Iranian capital of Susa. This means that the contemporary Iranian instruments such as the tanbur and setar are distantly related to the European guitar, as they all derive ultimately from the same ancient origins, but by very different historical routes and influences.
During the Middle Ages, guitars with three, four, and five strings were already in use. The Guitarra Latina had curved sides and is thought to have come to Spain from elsewhere in Europe. The so-called Guitarra Morisca, brought to Spain by the Moors, had an oval soundbox and many sound holes on its soundboard. By the 15th century, a four course double-string guitar called the vihuela de mano, half way between the lute and the guitar, appeared and became popular in Spain and spread to Italy; and by the sixteenth century, a fifth double-string had been added. During this time, composers wrote mostly in tablature notation. In the 17th century, influences from the vihuela and the renaissance five string guitar were combined in the baroque guitar. The baroque guitar quickly superseded the vihuela in popularity and Italy became the center of the guitar world. Leadership in guitar developments switched to Spain from the late 18th century, when the six string guitar quickly became popular at the expense of the five string guitars. During the 19th century, improved communication and transportation enabled performers to travel widely and the guitar gained greater popularity outside its old strongholds in Iberia, Italy and Latin America. During the 19th century the Spaniard, Antonio de Torres, gave the modern classical guitar its definitive form, with a broadened body, increased waist curve, thinned belly, improved internal bracing, single string courses replacing double courses, and a machined head replacing wooden tuning pegs. The modern classical guitar replaced older form for the accompaniment of song and dance called flamenco, and a modified version, known as the flamenco guitar, was created.
The gittern, often referred to as Renaissance guitar, is a musical instrument resembling a small lute or guitar. It is related to but is not a citole, another medieval instrument. The gittern was carved from a single piece of wood with a curved ("sickle-shaped") pegbox. An example has survived from around 1450.
See also Renaissance music.
The written history of the classical guitar can be traced back to the early sixteenth century with the development of the vihuela in Spain. While the lute was then becoming popular in other parts of Europe, the Spaniards did not take to it well because of its association with the Moors . They turned instead to the four string guitarra, adding two more strings to give it more range and complexity. In its most developed form, the vihuela was a guitar-like instrument with six double strings made of gut, tuned like a modern classical guitar with the exception of the third string, which was tuned half a step lower. It has a high sound and is rather large to hold. There are few still around.
See also Baroque music.
The earliest extant six string guitar was built in 1779 by Gaetano Vinaccia (1759 - after 1831) [14][15] in Naples, Italy. The Vinaccia family of luthiers is known for developing the mandolin. This guitar has been examined and does not show tell-tale signs of modifications from a double-course guitar.[16] The authenticity of guitars allegedly produced before the 1790s is often in question. This also corresponds to when Moretti's 6-string method appeared, in 1792.
See also Classical music era.
Contemporary concert guitars occasionally follow the Smallman design which replaces the fan braces with a much lighter balsa brace attached to the back of the sound board with carbon fiber. The balsa brace has a honeycomb pattern and allows the (now much thinner) sound board to support more vibrational modes. This leads to greater volume and longer sustain but compromises the subtle tonalities of the Spanish sound.
The modern classical guitar is usually played in a seated position, with the instrument resting on the left lap - and the left foot placed on a footstool. Alternatively - if a footstool is not used - a guitar support can be placed between the guitar and the left lap (the support usually attaches to the instrument's side with suction cups). (There are of course exceptions, with some performers choosing to hold the instrument another way.)
Right-handed players use the fingers of the right hand to pluck the strings, with the thumb plucking from the top of a string downwards and the other fingers plucking from the bottom of string upwards. The little finger in classical technique as it evolved in the 20th century is used only to ride along with the ring finger without striking the strings and to thus physiologically facilitate the ring finger's motion. Some modern guitarists, such as Štěpán Rak, use the little finger independently, compensating for the little finger's shortness by maintaining an extremely long fingernail. In contrast, Flamenco technique, and classical compositions evoking Flamenco, employ the little finger semi-independently in the Flamenco four-finger rasgueado, that rapid strumming of the string by the fingers in reverse order employing the back of the fingernail which is such a familiar characteristic of Flamenco.
As with other plucked instruments (such as the lute), the musician directly touches the strings (usually plucking) to produce the sound. This has important consequences: Different tone/timbre (of a single note) can be produced by plucking the string in different manners and in different positions.
Guitarists have a lot of freedom within the mechanics of playing the instrument. Often these decisions with influence on tone/timbre - factors include:
Right Hand:
Left Hand:
Both Hands/Other:
Since it is the hands and fingers that pluck the string and every person has different fingers, there are great differences in playing between guitarists; who often spend a lot of time finding their own way of playing that suits them best in terms of specific objectives: tone-production ("beauty"/quality of tone), minimum noise (e.g. clicking), large dynamic range (from soft to controlled loud), minimum (muscle) effort, fast "motion-recovery" (fast plucking when desired), healthy movement in fingers, wrist, hand and arm.
John Williams has remarked[17] that since guitarists find it superficially very easy to play even things such as melody with accompaniment (e.g. Giuliani), [some guitarists'] "approach to tone production is also superficial, with little or no consideration given to voice matching and tonal contrasts".
The classical guitar repertoire in practical terms includes not only music written specifically for the classical guitar, but also music written for the guitar's predecessors and related instruments. These include the vihuela, popular in sixteenth-century Spain, and the lute used everywhere else in Europe in the Renaissance and Baroque eras. Music written specifically for the classical guitar dates from the addition of the sixth string (the baroque guitar normally had five pairs of strings) in the late 18th century.
A guitar recital may include a variety of works, e.g. works written originally for the lute or vihuela by composers such as John Dowland (b. England 1563) and Luis de Narváez (b. Spain c. 1500), and also music written for the harpsichord by Domenico Scarlatti (b. Italy 1685), for the baroque lute by Sylvius Leopold Weiss (b. Germany 1687), for the baroque guitar by Robert de Visée (b. France c. 1650) or even Spanish-flavored music written for the piano by Isaac Albéniz (b. Spain 1860) and Enrique Granados (b. Spain 1867). The most important composer who did not write for the guitar but whose music is often played on guitar is Johann Sebastian Bach (b. Germany 1685) whose works for solo violin and solo cello as well as those written for baroque lute have proved to be highly adaptable for the guitar. Indeed, they have become core repertoire for guitarists.
Of the music written originally for guitar the earliest important composers are from the classical period and include Fernando Sor (b. Spain 1778) and Mauro Giuliani (b. Italy 1781) both of whom wrote in a style strongly influenced by Viennese classicism. In the nineteenth century guitar composers such as Johann Kaspar Mertz (b. Slovakia, Austria 1806) were strongly influenced by the dominance of the piano. It is not until the end of the century that the guitar began to emerge with its own unique atmosphere. Francisco Tárrega (b. Spain 1852) was central to this, sometimes incorporating some stylized aspects of flamenco, which has Moorish influences, into his romantic miniatures. This was part of the phenomenon of musical nationalism that was part of the wider European mainstream in the late nineteenth century. The aforementioned piano composers Albéniz and Granados were central to this movement and their evocation of the guitar was so successful that guitarists have largely appropriated their music for piano to the guitar. Guitarists who were active at that time, such as Angel Barrios (Spain, 1882–1964) contributed to the incorporation of flamenco style (e.g. the Phrygian mode) and flamenco guitar techniques such as rasgueado.
With the twentieth century and the wide-ranging performances of artists such as Andrés Segovia and Agustin Barrios-Mangore the guitar began to regain some of the popularity it had lost to the harpsichord and piano in the eighteenth century. It again became a popular instrument, but not always in its classical version. The steel-string and electric guitars, integral to the rise of rock and roll in the post-WWII era, became more widely played in North America and the English speaking world. The classical guitar also became widely popular again. Barrios composed many excellent works and brought into the mainstream the characteristics of Latin American music, as did the Brazilian composer Heitor Villa-Lobos. Andrés Segovia commissioned many works from Spanish composers such as Federico Moreno Torroba and Joaquin Rodrigo, Italians such as Mario Castelnuovo-Tedesco and Latin American composers such as Manuel M. Ponce of Mexico, Agustin Barrios-Mangore of Paraguay, Leo Brouwer of Cuba, Antonio Lauro of Venezuela, Enrrique Solares of Guatemala. Julian Bream of Great Britain managed to get nearly every British composer from William Walton to Benjamin Britten to Peter Maxwell Davies to write significant works for guitar. Bream's collaborations with tenor Peter Pears also resulted in song-cycles by Britten, Lennox Berkeley and others. There are also significant works by composers such as Hans Werner Henze of Germany. The classical guitar also became widely used in popular music and rock & roll in the 1960s after guitarist Mason Williams popularized the instrument in his instrumental hit Classical Gas. Guitarist Christopher Parkening is quoted in the book Classical Gas: The Music of Mason Williams as saying that it is the most requested guitar piece besides Malagueña and perhaps the best known instrumental guitar piece today.
During the period from approximately 1780 to 1850 the guitar was an extremely popular instrument with numerous composers and performers such as
There is even an image from 1825 by Charles de Marescot entitled "La Guitaromanie".
The classical guitar is distinguished by a number of characteristics:
The fretboard (also called the fingerboard) is a piece of wood embedded with metal frets that constitutes the top of the neck. It is flat or slightly curved. The curvature of the fretboard is measured by the fretboard radius, which is the radius of a hypothetical circle of which the fretboard's surface constitutes a segment. The smaller the fretboard radius, the more noticeably curved the fretboard is. Fretboards are most commonly made of ebony, but may also be made of rosewood or of phenolic composite ("micarta").
Frets are the metal strips (usually nickel alloy or stainless steel) embedded along the fingerboard and placed at points that divide the length of string mathematically. The strings' vibrating length is determined when the strings are pressed down behind the frets. Each fret produces a different pitch and each pitch spaced a half-step apart on the 12 tone scale. The ratio of the widths of two consecutive frets is the twelfth root of two (), whose numeric value is about 1.059463. The twelfth fret divides the string in two exact halves and the 24th fret (if present) divides the string in half yet again. Every twelve frets represents one octave. This arrangement of frets results in equal tempered tuning.
A classical guitar's frets, fretboard, tuners, headstock, all attached to a long wooden extension, collectively constitute its neck. The wood used to make the fretboard will usually differ from the wood in the rest of the neck. The bending stress on the neck is considerable, particularly when heavier gauge strings are used (see Strings).
This is the point at which the neck meets the body of the guitar. In the traditional Spanish neck joint the neck and block are one piece with the sides inserted into slots cut in the block. Other necks are built separately and joined to the body either with a dovetail joint, mortise or flush joint. These joints are usually glued and can be reinforced with mechanical fasteners. Recently many manufacturers use bolt on fasteners. Bolt on neck joints were once associated only with less expensive instruments but now some top manufacturers and hand builders are using variations of this method. Some people believed that the Spanish style one piece neck/block and glued dovetail necks have better sustain, but testing has failed to confirm this. While most traditional Spanish style builders use the one piece neck/heel block, Fleta a prominent Spanish builder used a dovetail joint due to the influence of his early training in violin making. One reason for the introduction of the mechanical joints was to make it easier to repair necks. This is more of a problem with steel string guitars than with nylon strings which have about half the string tension. This is why nylon string guitars often don't include a truss rod either.
The body of the instrument is a major determinant of the overall sound variety for acoustic guitars. The guitar top, or soundboard, is a finely crafted and engineered element often made of spruce, red cedar or mahogany. This thin (often 2 or 3 mm thick) piece of wood, strengthened by different types of internal bracing, is considered to be the most prominent factor in determining the sound quality of a guitar. The majority of the sound is caused by vibration of the guitar top as the energy of the vibrating strings is transferred to it. Different patterns of wood bracing have been used through the years by luthiers (Torres, Hauser, Ramírez, Fleta, and C.F. Martin being among the most influential designers of their times); to not only strengthen the top against collapsing under the tremendous stress exerted by the tensioned strings, but also to affect the resonation of the top. The back and sides are made out of a variety of woods such as mahogany, Indian rosewood and highly regarded Brazilian rosewood (Dalbergia nigra). Each one is chosen for its aesthetic effect and structural strength, and such choice can also play a significant role in determining the instrument's timbre. These are also strengthened with internal bracing, and decorated with inlays and purfling.
The body of a classical guitar is a resonating chamber which projects the vibrations of the body through a sound hole, allowing the acoustic guitar to be heard without amplification. The sound hole is normally a round hole in the top of the guitar (under the strings), though some may have different placement, shapes or multiple holes.
An instrument's maximum volume is determined by how much air it can move.
The top, back and sides of a classical guitar body are very thin, so a flexible piece of wood called kerfing (because it is often scored, or kerfed to allow it to bend with the shape of the rim) is glued into the corners where the rim meets the top and back. This interior reinforcement provides 5 to 20 mm of solid gluing area for these corner joints.
During final construction, a small section of the outside corners is carved or routed out and then filled with binding material on the outside corners and decorative strips of material next to the binding, which are called purfling. This binding serves to seal off the endgrain of the top and back. Binding and purfling materials are generally made of either wood or high quality plastic materials.
The main purpose of the bridge on a classical guitar is to transfer the vibration from the strings to the soundboard, which vibrates the air inside of the guitar, thereby amplifying the sound produced by the strings. The bridge holds the strings in place on the body. Also, the position of the saddle, usually a strip of bone or plastic across the bridge upon which the strings rest, determines the distance to the nut (at the top of the fingerboard).
The modern full size classical guitar has a scale length[20] of around 650 mm (25.6 inches), with an overall instrument length of 965–1016 mm (38-40 inches). The scale length has remained quite consistent since it was chosen by the originator of the instrument, Antonio de Torres. This length was probably chosen as twice the length of a violin string. As the guitar is tuned to one octave below that of the violin, the same size gut could be used for the 1st strings of both instruments.
Smaller scale instruments are produced to assist children in learning the instrument as the smaller scale leads to the frets being closer together making it easier for smaller hands. The scale size for the smaller guitars is usually in the range 484–578 mm (19-22.5 inches) with an instrument length of 785–915 mm (31-36 inches). Full size instruments are sometimes referred to as 4/4, while the smaller sizes are 3/4, 1/2 or 1/4.[21]
These sizes are not absolute, as luthiers may choose variations around these nominal scale lengths;

A variety of different tunings are used. The most common by far, which one could call the "standard tuning" is:
The above order, is the tuning from the 1st string (highest-pitched string e', physically visible as the bottom string when correctly holding a guitar) to the 6th string (lowest-pitched string E, physically visible as the top string, and hence usually comfortable to be plucked with the thumb).
String | Sci. pitch | Helmholtz pitch | Interval from middle C | Semitones from A440 | Freq., if using an Equal temperament tuning (using ) |
---|---|---|---|---|---|
1st (highest pitch) | E4 | e' | major third above | -5 | 329.63 Hz |
2nd | B3 | b | minor second below | -10 | 246.94 Hz |
3rd | G3 | g | perfect fourth below | -14 | 196.00 Hz |
4th | D3 | d | minor seventh below | -19 | 146.83 Hz |
5th | A2 | A | minor tenth below | -24 | 110 Hz |
6th (lowest pitch) | E2 | E | minor thirteenth below | -29 | 82.41 Hz |
This tuning is such that neighboring strings are at most 5 semitones apart. There are also a variety of commonly used alternate tunings.
