# Classical guitar technique

The classical guitar technique is a fingerstyle technique used by classical guitarists to play classical guitar music on a classical guitar.

## General

Classical guitar technique can be organised broadly into subsections for the right hand, the left hand, and miscellaneous. In guitar performance elements such as musical dynamic and tonal variation are mostly determined by the hand that physically produces the sound. In other words, the hand that plucks the strings defines the musical expression. Historically this role has been assigned to the dominant hand which, for the majority of players, is the right hand. Similar reasoning is behind string players using the right hand for controlling the bow. In the following discussion the role of the hands should be reversed when considering left-handed players.

## Posture

The classical guitar is generally held on the left leg which is supported by a foot stool or the guitar is raised by some other device to bring it to a position central to the player's body. Basic considerations in determining a chosen playing position include:
* the physical stability of the instrument
* ensuring the freedom of both hands such that they have thorough access to the instrument and can meet all technical demands without having to support the instrument
* elimination of general muscular tension in the assumed body position

## Right hand technique

The thumb and three largest fingers of the right hand pluck the strings. The normal position is for the hand to be shaped as if it were loosely holding an apple with the wrist slightly bent, the forearm resting on the upper large bout of the guitar, and the fingers near the strings. Plucking the strings usually involves making contact first with the fleshy part of the fingertip and then letting the string glide over the tip of the fingernail as the string is plucked. The two primary plucking techniques are:
* Rest-stroke (apoyando), in which the finger that plucks the string rests on the next string afterwards; and
* Free-stroke (tirando), in which the finger hits nothing after plucking the string.
Rest-stroke produces a more "deliberate" sound and is good for bringing the melody out in music where the harmony competes for attention. Free-stroke sounds "lighter" and makes it possible to play fast passages more easily.
One of the tenets of right hand technique in scale passages is alternation. That is, no right hand finger should be used to play two notes in a row (excluding the thumb, which is often called upon to play a sequence of bass notes). Typically, for scale-like passages the index and middle fingers alternate. When an arpeggiated harmony is being played with the thumb (p), index (i) and middle (m) fingers, the ring finger (a) may play a melody above the harmony. In the tremolo technique the thumb plays a bass note followed by the fingers which play the same treble note three times: pami, pami, pami etc (Recuerdos de la Alhambra by Francisco Tárrega is a famous example of this technique).
The position of the right hand can be used to influence the tone of the sound produced by a classical guitar. The wealth of sonic possibilities enables performers to add contrast and color to their performances well beyond the simple volume changes available to, say, pianists. When the strings are plucked close to the bridge the position is called sul ponticello and the notes sound "twangy" and "nasal". When the strings are plucked over the fingerboard of the guitar the position is termed sul tasto and the tone becomes fuller and "sweet" (termed dolce in Italian, see List of musical terminology page). The angle at which the fingers hit the strings can also affect the timbre of the sound.
The term pizzicato simply refers to plucking the strings in music for bowed instruments. In classical guitar however, it refers to placing the side of the hand below the little finger across all of the strings very close to the bridge and then plucking the strings with the fingers. This produces a muted sound and is referred to as palm-muting in electric guitar parlance. Tambour is the technique where many or all of the strings are played at once by hitting them (usually near the bridge) with the side of the (outstretched) thumb. Both tambor and pizzicato can be heard in Aconquija by Barrios.
The right hand fingers are used to stop notes from ringing past their duration as indicated by the music. This is more often an issue with open string bass notes which tend to ring on for some time. To stop the notes the right hand thumb (usually) rests on the ringing string to stop it. This can pose a significant challenge to the guitarist as he or she needs to attend to each bass note twice, once to start it and once to stop it. The same technique can be used to create a staccato effect.
Trills are usually played on one string using various combinations of left hand slurs, also known as legados or hammer-on and pull-offs. Cross-string trills utilising two or three strings are also possible. In this case the trill usually takes the form of low-high-low and can be executed thus: The left hand stops, say the D# on the fourth fret of the second string, the right hand middle finger plays that note then the index finger "strums" the first and second strings producing: D#-E-D#. The difference between a cross-string trill and an ordinary trill is that the cross-string trill allows both notes to sound against each other. This technique is often used in Baroque music although it is debatable as to whether it was the most common practice of the period.

### Nails

Modern practice generally makes use of the nails of the right hand in combination with the flesh of the fingertips in order to pluck the strings. During the 19th century many players, including celebrated guitarists such as Fernando Sor, Francisco Tárrega and his pupil Emilio Pujol played using the flesh of the fingertip, in common with lute technique.

### Strumming

* Rasgueado See main article Rasgueado. Rasgueado or rasgueo is a technical strum in flamenco and classical guitar that includes the use of the back of the fingernails in sequence to give the impression of a very rapid strum. There are several types of rasgueado that employ differing combinations of fingers and thumb allowing for a variety of rhythmical accentuations and subdivisions of the beat.
* Use the palm-side of the thumb joint to lightly strum strings, producing a soft, low sound.
* Use the thumb nail to produce a bright sound.
* A simple combination of both fingers and thumb, the thumb striking the lowest strings and fingers picking the upper notes of the chord from lowest to highest strings in rapid succession.
