The guitar is a musical instrument of the chordophone family, being
a stringed instrument played by plucking, either with fingers or a
pick. The guitar consists of a body with a rigid neck to which the
strings, generally six in number but sometimes more, are attached.
Guitars are traditionally constructed of various woods and strung
with animal gut or, more recently, with either nylon or steel
strings. Some modern guitars are made of polycarbonate materials.
Guitars are made and repaired by luthiers. There are two primary
families of guitars: acoustic and electric.
Acoustic guitars (and similar instruments) with hollow bodies, have
been in use for over a thousand years. There are three main types
of modern acoustic guitar: the classical guitar (nylon-string
guitar), the steel-string acoustic guitar, and the archtop guitar.
The tone of an acoustic guitar is produced by the vibration of the
strings, which is amplified by the body of the guitar, which acts
as a resonating chamber. The classical guitar is often played as a
solo instrument using a comprehensive fingerpicking technique.
Electric guitars, introduced in the 1930s, rely on an amplifier
that can electronically manipulate tone. Early amplified guitars
employed a hollow body, but a solid body was found more suitable.
Electric guitars have had a continuing profound influence on
popular culture. Guitars are recognized as a primary instrument in
genres such as blues, bluegrass, country, flamenco, jazz, jota,
mariachi, reggae, rock, soul, and many forms of pop.
Before the development of the electric guitar and the use of
synthetic materials, a guitar was defined as being an instrument
having "a long, fretted neck, flat wooden soundboard, ribs, and a
flat back, most often with incurved sides". The term is used to
refer to a number of related instruments that were developed and
used across Europe beginning in the 12th century and, later, in the
Americas. These instruments are descended from ones that existed in
ancient central Asia and India. For this reason guitars are
distantly related to modern instruments from these regions,
including the tanbur, the setar, and the sitar. The oldest known
iconographic representation of an instrument displaying the
essential features of a guitar is a 3,300 year old stone
carving of a Hittite bard.
The modern word " guitar ", and its antecedents, have been applied
to a wide variety of cordophones since ancient times and as such is
the cause of confusion. The English word "guitar" , the German
"gitarre" , and the French "guitare" , were adopted from the
Spanish guitarra , which comes from the Andalusian Arabic qitara
itself derived from the Latin word cithara , which in turn came
from the earlier Greek word kithara ( ), a descendant of Old
Persian sihtar ( ) ( Tar means string in Persian).
Although the word guitar is descended from the Roman word cithara ,
the modern guitar itself is not generally believed to have
descended from the roman instrument. It is often claimed the modern
guitar has it roots in in the arrival of the four-string oud,
introduced by the invading Moors into Iberia in the 8th century.
Another frequently suggested influence is the six-string
Scandinavian lut (lute), which gained in popularity in areas of
Viking incursions across medieval Europe. Often depicted in
carvings c. 800 AD, the Norse hero Gunther (also known as Gunnar),
played a lute with his toes as he lay dying in a snake-pit, in the
legend of Siegfried.
Two four string medieval "guitars" that were in use by 1200 were
the immediate ancestors of the modern guitar: the guitarra moresca
(Moorish guitar) and guitarra latina (Latin guitar). The guitarra
moresca is an instrument that displays strong Moorish influences;
it had a rounded back, wide fingerboard, and several soundholes.
The guitarra latina had a single soundhole and a narrower neck. By
the 14th century the qualifiers "moresca" and "latina" had largely
been dropped and these two four course instruments were usually
simply referred to as guitars.
The Spanish vihuela or (in Italian) " viola da mano ", a
guitar-like instrument of the 15th and 16th centuries, is widely
considered to have been a seminal influence in the development of
the modern guitar. It had six courses (usually), lute-like tuning
in fourths and a guitar-like body, although early representations
reveal an instrument with a sharply-cut waist. It was also larger
than the contemporary four course guitars. By the late 15th century
some vihuelas were played with a bow, leading to the development of
the viol. By the sixteenth century the vihuela's construction had
more in common with the modern guitar, with its curved one-piece
ribs, than with the viols, and more like a larger version of the
contemporary four-course guitars. The vihuela enjoyed only a short
period of popularity in Spain and Italy during an era dominated
elsewhere in Europe by the lute; the last surviving published music
for the instrument appeared in 1576. Meanwhile the five-course
baroque guitar, which was documented in Spain from the middle of
the 16th century, enjoyed popularity, especially in Spain, Italy
and France from the late 16th century to the mid 18th century.
Confusingly, in Portugal, the word vihuela referred to the guitar,
whereas guitarra meant the "Portuguese guitar", a variety of
cittern. Types of guitars
The guitar player (c. 1672), by Johannes Vermeer
Guitars can be divided into two broad categories, acoustic and
electric: Acoustic guitars
There are several notable subcategories within the acoustic guitar
group: classical and flamenco guitars; steel-string guitars, which
include the flat-topped, or "folk," guitar; twelve-string guitars;
and the arched-top guitar. The acoustic guitar group also includes
unamplified guitars designed to play in different registers, such
as the acoustic bass guitar, which has a similar tuning to that of
the electric bass guitar. Renaissance and Baroque guitars
These are the gracile ancestors of the modern classical guitar.
They are substantially smaller and more delicate than the classical
guitar, and generate a much quieter sound. The strings are paired
in courses as in a modern 12-string guitar, but they only have four
or five courses of strings rather than six. They were more often
used as rhythm instruments in ensembles than as solo instruments,
and can often be seen in that role in early music performances.
(Gaspar Sanz' Instrucción de Música sobre la Guitarra Española of
1674 constitutes the majority of the surviving solo corpus for the
era.) Renaissance and Baroque guitars are easily distinguished
because the Renaissance guitar is very plain and the Baroque guitar
is very ornate, with ivory or wood inlays all over the neck and
body, and a paper-cutout inverted "wedding cake" inside the hole.
Classical guitars
Eminent South American guitarist, Agustin Barrios These are
typically strung with nylon strings, plucked with the fingers,
played in a seated position and are used to play a diversity of
musical styles including classical music. The classical guitar's
wide, flat neck allows the musician to play scales, arpeggios, and
certain chord forms more easily and with less adjacent string
interference than on other styles of guitar. Flamenco guitars are
very similar in construction, but are associated with a more
percussive tone. In Mexico, the popular mariachi band includes a
range of guitars, from the tiny requinto to the guitarrón, a guitar
larger than a cello, which is tuned in the bass register. In
Colombia, the traditional quartet includes a range of instruments
too, from the small bandola (sometimes known as the
Deleuze-Guattari, for use when traveling or in confined rooms or
spaces), to the slightly larger tiple, to the full sized classical
guitar. The requinto also appears in other Latin-American countries
as a complementary member of the guitar family, with its smaller
size and scale, permitting more projection for the playing of
single-lined melodies. Modern dimensions of the classical
instrument were established by the Spaniard Antonio de Torres
Jurado (1817-1892). Extended-range classical guitar
An Extended-range classical guitar is a classical guitar with more
than 6 strings, usually up to 13. Flamenco guitars
The flamenco guitar is similar to the classical guitar, but of
lighter construction, with a cypress body and spruce top. Tuning
pegs like those of a violin are traditional, although many modern
flamenco guitars have machine heads. A distinguishing feature of
all flamenco guitars is the tapping plates ( golpeadores ) glued to
the table, to protect them against the taps with the fingernails
that are an essential feature of the flamenco style. Many modern
soloists (following the lead of Paco de Lucía) play what is called
a flamenca negra, a hybrid of the flamenco and classical guitar
constructions Flat-top (steel-string) guitars
Similar to the classical guitar, however, within the varied sizes
of the steel-stringed guitar the body size is usually significantly
larger than a classical guitar, and has a narrower, reinforced neck
and stronger structural design. The robust X-bracing typical of the
steel-string was developed in the 1840s by German-American luthiers
of whom C. F. Martin is the best known. Originally used on
gut-strung instruments, the strength of the system allowed the
guitar to withstand the additional tension of steel strings when
this fortunate combination arose in the early 20th century. The
steel strings produce a brighter tone, and according to many
players, a louder sound. The acoustic guitar is used in many kinds
of music including folk, country, bluegrass, pop, jazz, and blues.
Many variations are possible from the roughly classical-sized OO
and Parlour to the large Dreadnought and Jumbo. Ovation makes a
modern variation, with a rounded back/side assembly molded from
artificial materials. Archtop guitars
These are steel-string instruments in which the top (and often the
back) of the instrument are carved from a solid billet in a curved
rather than a flat shape; this violin-like construction is usually
credited to the American Orville Gibson (1856-1918). Lloyd Loar of
the Gibson Mandolin-Guitar Mfg. Co introduced the violin-inspired
f-hole design now usually associated with archtop guitars, after
designing a style of mandolin of the same type. The typical archtop
guitar has a large, deep, hollow body whose form is much like that
of a mandolin or violin family instrument. Nowadays, most archtops
are equipped with magnetic pickups and are therefore both acoustic
and electric. F-hole archtop guitars were immediately adopted upon
their release by both jazz and country musicians and have remained
particularly popular in jazz music, usually with flatwound strings.
Selmer-Maccaferri guitars
These are usually played by those who follow the style of Django
Reinhardt. It is an unusual-looking instrument, distinguished by a
fairly large body with squarish bouts, and either a "D"-shaped or
longitudinal oval soundhole. The strings are gathered at the tail
like an archtop guitar, but the top is formed from thin spruce
(like a flat-top or classical) forced into a shallow dome. It also
has a wide fingerboard and slotted head like a nylon-string guitar.
The loud volume and penetrating tone make it suitable for
single-note soloing and it is frequently employed as a lead
instrument in gypsy swing. An 8-string baritone tricone resonator
guitar. Resonator , resophonic or Dobro guitars
All three principal types of resonator guitars were invented by the
Slovak-American John Dopyera (1893-1988) for the National and Dobro
( Do pyera Bro thers) companies. Similar to the flat top guitar in
appearance, but with a body that may be made of brass,
nickel-silver, or steel as well as wood, the sound of the resonator
guitar is produced by one or more aluminum resonator cones mounted
in the middle of the top. The physical principle of the guitar is
therefore similar to the loudspeaker. The original purpose of the
resonator was to produce a very loud sound; this purpose has been
largely superseded by electrical amplification, but the resonator
guitar is still played because of its distinctive tone. Resonator
guitars may have either one or three resonator cones. The method of
transmitting sound resonance to the cone is either a "biscuit"
bridge, made of a small piece of hardwood at the vertex of the cone
(Nationals), or a "spider" bridge, made of metal and mounted around
the rim of the (inverted) cone (Dobros). Three-cone resonators
always use a specialized metal bridge. The type of resonator guitar
with a neck with a square cross-section called "square neck" or
"Hawaiian" is usually played face up, on the lap of the seated
player, and often with a metal or glass slide. The round neck
resonator guitars are normally played in the same fashion as other
guitars, although slides are also often used, especially in blues.
12-string guitars
The twelve-string guitar usually has steel strings and is widely
used in folk music, blues, and rock and roll. Rather than having
only six strings, the 12-string guitar has six courses made up of
two strings each, like a mandolin or lute. The highest two courses
are tuned in unison, while the others are tuned in octaves. The
12-string guitar is also made in electric forms. Russian
guitars
These seven-string acoustic guitars were the norm for Russian
guitarists throughout the 19th and well into the 20th centuries.
The Russian guitar is traditionally tuned to open G major. Acoustic
bass guitars
Prime and bass acoustic guitars These have steel strings or gut
strings and often the same tuning as an electric bass guitar.
Guitarrón
The guitarrón is a very large, deep-bodied Mexican 6-string
acoustic bass played in mariachi bands. It is fretless with heavy
gauge nylon strings, and is usually played by doubling notes at the
octave, which is facilitated by the unusual tuning of A D G C E A.
Tenor guitars
A number of classical guitarists call the Niibori prime guitar a
"Tenor Guitar" on the grounds that it sits in pitch between the
alto and the bass. Elsewhere [ citation needed ] the name is taken
for a 4-string guitar with a scale length of 23" (585 mm)
about the same as a Terz Guitar. The tenor guitar is tuned in
fifths, C G D A, as is the tenor banjo and the cello. It is
generally accepted [ citation needed ] that the tenor guitar was
created to allow a tenor banjo player to follow the fashion as it
evolved from Dixieland Jazz towards the more progressive Jazz that
featured guitar. It allows a tenor banjo player to provide a
guitar-based rhythm section with little to learn. A small minority
of players (such as Nick Reynolds of the Kingston Trio) close tuned
the instrument to D G B E to produce a deep instrument that could
be played with the 4-note chord shapes found on the top 4 strings
of the guitar or ukulele. The deep pitch warrants the wide-spaced
chords that the banjo tuning permits, and the close tuned tenor
does not have the same full, clear sound. Harp guitars
Harp Guitars are difficult to classify as there are many variations
within this type of guitar. They are typically rare and uncommon in
the popular music scene. Most consist of a regular guitar, plus
additional 'harp' strings strung above the six normal strings. The
instrument is usually acoustic and the harp strings are usually
tuned to lower notes than the guitar strings, for an added bass
range. Normally there is neither fingerboard nor frets behind the
harp strings. Some harp guitars also feature much higher pitch
strings strung below the traditional guitar strings. The number of
harp strings varies greatly, depending on the type of guitar and
also the player's personal preference (as they have often been made
to the player's specification). The Pikasso guitar; 4 necks, 2
sound holes, 42 strings] and also the Oracle Harp Sympitar; 24
strings (with 12 sympathetic strings protruding through the neck)
are modern examples. Extended-range guitars
For well over a century guitars featuring seven, eight, nine, ten
or more strings have been used by a minority of guitarists as a
means of increasing the range of pitch available to the player.
Usually, it is bass strings that are added. Classical guitars with
an extended range are useful for playing lute repertoire, some of
which was written for lutes with more than six courses. A typical
example is the modern 11 string archguitar , invented and played by
Peter Blanchette. Guitar battente
The battente is smaller than a classical guitar, usually played
with four or five metal strings. It is mainly used in Calabria (a
region in southern Italy) to accompany the voice. Electric
guitars
Main article: Electric guitar Glen Campbell playing a Fender
electric guitar with three single-coil pickups

This Fender
Stratocaster has features common to many electric guitars: multiple
pickups, a vibrato unit/tremolo bar, and volume and tone knobs.
Pickups are transducers attached to a guitar that detect (or "pick
up") string vibrations and convert the mechanical energy of the
string into electrical energy. The resultant electrical signal can
then be electronically amplified. The most common type of pickup is
electromagnetic in design. These contain magnets that are tightly
wrapped in a coil, or coils, of copper wire. Such pickups are
usually placed right underneath the guitar strings. Electromagnetic
pickups work on the same principles and in a similar manner to an
electrical generator. The vibration of the strings causes a small
voltage to be created in the coils surrounding the magnets; this
signal voltage is later amplified.
Traditional electromagnetic pickups are either single-coil or
double-coil. Single-coil pickups are susceptible to noise induced
from electric fields, usually mains-frequency (60 or 50 hertz) hum.
The introduction of the double-coil humbucker in the mid-1950s did
away with this problem through the use of two coils, one of which
is wired in a reverse polarity orientation.
The types and models of pickups used can greatly affect the tone of
the guitar. Typically, humbuckers, which are two magnet coil
assemblies attached to each other are traditionally associated with
a heavier sound. Single-coil pickups, one magnet wrapped in copper
wire, are used by guitarists seeking a brighter, twangier sound
with greater dynamic range.
Modern pickups are tailored to the sound desired. A commonly
applied approximation used in selection of a pickup is that less
wire (lower DC resistance) = brighter sound, more wire = "fat"
tone. Other options include specialized switching that produces
coil-splitting, in/out of phase and other effects. Guitar circuits
are either active, needing a battery to power their circuit, or, as
in most cases, equipped with a passive circuit.
Fender Stratocaster type guitars generally utilize three
single-coil pickups, while most Gibson Les Paul types use humbucker
pickups.
Piezoelectric, or piezo, pickups represent another class of pickup.
These employ piezoelectricity to generate the musical signal and
are popular in hybrid electro-acoustic guitars. A crystal is
located under each string, usually in the saddle. When the string
vibrates, the shape of the crystal is distorted, and the stresses
associated with this change produce tiny voltages across the
crystal that can be amplified and manipulated.
Some piezo-equipped guitars use what is known as a hexaphonic
pickup. "Hex" is a prefix meaning six. In a hexaphonic pickup
separate outputs are obtained from discrete piezoelectric pickups
for each of the six strings. This arrangement allows the signal to
be easily modified by on-board modelling electronics, as in the
Line 6 Variax brand of electric guitars; the guitars allow for a
variety of different sounds to be obtained by digitally
manipulating the signal. This allows a guitar to mimic many vintage
models of guitar, as well as output alternate tunings without the
need to adjust the strings.
Another use for hexaphonic pickups is to send the output signals to
a MIDI interpretation device, which determines the note pitch,
duration, attack and decay characteristics and so forth. The MIDI
(Musical Instrument Digital Interface) interpreter then sends the
note information to a sound bank device. The resulting sound can
closely mimic numerous types of instruments. Electronics
On guitars that have them, these components and the wires that
connect them allow the player to control some aspects of the sound
like volume or tone. These at their simplest consist of passive
components such as potentiometers and capacitors, but may also
include specialized integrated circuits or other active components
requiring batteries for power, for preamplification and signal
processing, or even for assistance in tuning. In many cases the
electronics have some sort of shielding to prevent pickup of
external interference and noise. Lining, Binding, and Purfling
The top, back and ribs of an acoustic guitar body are very thin (1
2 mm), so a flexible piece of wood called lining is glued into
the corners where the rib meets the top and back. This interior
reinforcement provides 5 to 20 mm of solid gluing area for
these corner joints. Solid linings are often used in classical
guitars, while kerfed lining is most often found in steel string
acoustics. Kerfed lining is also called kerfing (because it is
scored, or kerfed to allow it to bend with the shape of the
rib).
During final construction, a small section of the outside corners
is carved or routed out and 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 end grain of the top and back. Purfling can also appear on the
back of an acoustic guitar, marking the edge joints of the two or
three sections of the back.
Binding and purfling materials are generally made of either wood or
plastic. Bridge
Main article: Bridge (instrument)
The main purpose of the bridge on an acoustic 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.
On all electric, acoustic and original guitars, the bridge holds
the strings in place on the body. There are many varied bridge
designs. There may be some mechanism for raising or lowering the
bridge to adjust the distance between the strings and the fretboard
(action), and/or fine-tuning the intonation of the instrument. Some
are spring-loaded and feature a "whammy bar", a removable arm that
lets the player modulate the pitch by moving the bridge back and
forth. The whammy bar is sometimes also referred to as a "tremolo
bar" (see Tremolo for further discussion of this term the effect of
rapidly changing pitch produced by a whammy bar is more correctly
called "vibrato"). Some bridges also allow for alternate tunings at
the touch of a button.
On almost all modern electric guitars, the bridge is adjustable for
each string so that intonation stays correct up and down the neck.
If the open string is in tune but sharp or flat when frets are
pressed, the bridge can be adjusted with a screwdriver or hex key
to remedy the problem. In general, flat notes are corrected by
moving the bridge forward and sharp notes by moving it backwards.
On an instrument correctly adjusted for intonation, the actual
length of each string from the nut to the bridge saddle is slightly
but measurably longer than the scale length of the instrument. This
additional length is called compensation, which flattens all notes
a bit to compensate for the sharping of all fretted notes caused by
stretching the string during fretting. Saddle
The saddle of a guitar refers to the structure on or parallel to
the bridge. The saddle is most commonly found on acoustic guitars,
but some models of hollow-bodied electric guitars have it. Its
basic purpose is to hold the strings above the bridge and guitar,
and to mute the vibration of the string so the strings do not buzz
and/or damage themselves or the bridge. It is comparable in size
and function to the nut, and variations in its design are not
uncommon. Pickguard
Main article: Pickguard
Also known as a scratchplate. This is usually a piece of laminated
plastic or other material that protects the finish of the top of
the guitar from damage due to the use of a plectrum or fingernails.
Electric guitars sometimes mount pickups and electronics on the
pickguard. It is a common feature on steel-string acoustic guitars.
Vigorous performance styles such as flamenco, which can involve the
use of the guitar as a percussion instrument, call for a
scratchplate to be fitted to nylon-string instruments. Whammy Bar
(Tremolo Arm)
Main article: Tremolo arm
Many electric guitars are fitted with a vibrato and pitch bend
device known as a "tremolo bar (or arm)", "sissy bar", "wang bar",
"slam handle", "whammy handle", and "whammy bar". The latter two
terms led stompbox manufacturers to use the term 'whammy' in coming
up with a pitch raising effect introduced by popular guitar effects
pedal brand Digitech.
The tremolo arm is common enough that there is a technical term,
hard tail , for a guitar without one.
Leo Fender, who did much to create the electric guitar, also
created much confusion over the meaning of the terms "tremolo" and
"vibrato" by the naming the "tremolo" unit on many of his guitars
and also the "vibrato" unit on his "Vibrolux" amps. In general,
vibrato is a variation in pitch, whereas tremolo is a variation in
volume, so the tremolo bar is actually a vibrato bar and the
"Vibrolux" amps actually had a tremolo effect. However, following
Fender's example, electric guitarists traditionally reverse these
meanings when speaking of hardware devices and the effects they
produce. See vibrato unit for a more detailed discussion, and
tremolo arm for more of the history.
Another type of pitch bender is the B-Bender, a spring and lever
device mounted in an internal cavity of a solid body electric,
guitar that allows the guitarist to bend just the B string of the
guitar using a lever connected to the strap handle of the guitar.
The resulting pitch bend is evocative of the sound of the pedal
steel guitar. Guitar strap
A guitar strap is a strip of fabric with a leather or synthetic
leather piece on each end. It is made to hold a guitar via the
shoulders, at an adjustable length to suit the position favoured by
the guitarist.
Guitars have varying accommodations for attaching a strap. The most
common are strap buttons, also called strap pins, which are flanged
steel posts anchored to the guitar with screws. Two strap buttons
come pre-attached to virtually all electric guitars, and many
steel-string acoustic guitars. Strap buttons are sometimes replaced
with "strap locks" which connect the guitar to the strap more
securely.
The lower strap button is usually located at the bottom (bridge
end) of the body. The upper strap button is usually located near or
at the top (neck end) of the body: on the upper body curve, at the
tip of the upper "horn" (on a double cutaway), or at the neck joint
(heel). Some electrics, especially those with odd-shaped bodies,
have one or both strap buttons on the back of the body. Some
Steinberger electric guitars, owing to their minimalist and
lightweight design, have both strap buttons at the bottom of the
body. Rarely, on some acoustics, the upper strap button is located
on the headstock.
Some acoustic and classical guitars only have a single strap button
at the bottom of the body the other end must be tied onto the
headstock, above the nut and below the machine heads.
Some acoustic and classical guitars come with no strap buttons at
all. In this case, one or two strap buttons can usually be added to
the guitar, or a "classical guitar strap" (also called a "guitar
harness" or "neck strap") can be used, which supports the guitar by
hooking into the sound hole. Self-tuning guitars
Main article: Musical tuning
Self-tuning guitars are computerized guitars programmed to tune
themselves. The Gibson Robot Guitar, released in 2007, is often
mistaken as the first of this kind, but was preceded by the
Transperformance system by at least 20 years. Gibson has also
released a second, self-tuning model called the Dark Fire. [

Main article: Guitar tuning See also: Stringed instrument
tunings
The guitar is a transposing instrument. Its pitch sounds one octave
lower than it is notated on a score.
A variety of different tunings may be used. The most common tuning,
known as "Standard Tuning," has the strings tuned from a low E, to
a high E, traversing a two octave range EADGBE. When all strings
are played open the resulting chord is an Em7/add11.
A guitar using this tuning can tune to itself using the fact, with
a single exception, that the 5th fret on one string is the same
note as the next open string; that is, a 5th-fret note on the sixth
string is the same note as the open fifth string. The exception is
the interval between the second and third strings, in which the
4th-fret note on the third string is equivalent to the open second
string.
Standard tuning has evolved to provide a good compromise between
simple fingering for many chords and the ability to play common
scales with minimal left hand movement. Uniquely, the guitar's
tuning allows for repeatable patterns, which also facilitates the
ease of playing common scales. There are also a variety of commonly
used alternate tunings. Most of these are open tunings, i.e., the
unfretted strings produce a simple chord, such as a G Major chord.
Many open tunings, where all of the strings are tuned to a similar
note or chord, are popular for slide guitar playing. Alternate
tunings are used for two main reasons: the ease of playing and the
variation in tone that can be achieved.
Many guitarists use a long established, centuries-old tuning
variation where the lowest string is 'dropped' down a whole tone.
Known as Drop-D (or dropped D) tuning it is, from low to high,
DADGBE. This allows for open string tonic and dominant basses in
the keys of D and D minor. It also enables simple fifths
(powerchords) to be more easily played. Eddie Van Halen sometimes
uses a device known as a 'D Tuna,' which he patented. It is a small
lever, attached to the fine tuner of the 6th string on a Floyd Rose
tremolo, which allows him to easily drop that string from E to D.
Many contemporary rock bands retune all strings by several
semi-tones, making, for example, Drop-C or Drop-B tunings, However
this terminology is inconsistent with that of "drop-D" as "drop-D"
refers to dropping a single string to the named pitch. Often these
new tunings are also simply referred to as the "Standard" of the
note in question e.g. "D Standard" (DGcfad').
Some guitarists tune in straight fourths, avoiding the major third
between the third and second strings. While this makes playing
major and minor triads slightly more difficult, it facilitated
playing chords with more complicated extended structures. [
citation needed ] One proponent of the straight fourth tuning
(EADGCF) is Stanley Jordan.
As with all stringed instruments a large number of scordatura are
possible on the guitar. A common form of scordatura involves tuning
the 3rd string to F to mimic the standard tuning of the lute,
especially when playing renaissance repertoire originally written
for the lute. Guitar accessories
Though a guitar may be played on its own, there are a variety of
common accessories used for holding and playing the guitar.
Capotasto
Main article: Capo
A capo (short for capotasto ) is used to change the pitch of open
strings. Capos are clipped onto the fret board with the aid of
spring tension, or in some models, elastic tension. To raise the
guitar's pitch by one semitone, the player would clip the capo onto
the fret board just below the first fret. Its use allows players to
play in different keys without having to change the chord
formations they use. Because of the ease with which they allow
guitar players to change keys, they are sometimes referred to as
"cheaters" or the "hillbilly crutch." Classical performers are
known to use them to enable modern instruments to match the pitch
of historical instruments such as the renaissance lute. Slides
Main article: Slide Guitar
A slide, (neck of a bottle, knife blade or round metal bar) used in
blues and rock to create a glissando or 'Hawaiian' effect. The
necks of bottles were often used in blues and country music. Modern
slides are constructed of glass, plastic, ceramic, chrome, brass or
steel, depending on the weight and tone desired. An instrument that
is played exclusively in this manner, (using a metal bar) is called
a steel guitar or pedal steel. Slide playing to this day is very
popular in blues music and country music. Some slide players use a
so called Dobro guitar.
Some performers that have become famous for playing slide are
Robert Johnson, Elmore James, Ry Cooder, George Harrison, Bonnie
Raitt, Derek Trucks, Warren Haynes, Duane Allman, Muddy Waters,
Rory Gallagher, and George Thorogood. Plectrum
Main article: Guitar pick A variety of guitar picks
A "guitar pick" or "plectrum" is a small piece of hard material
generally held between the thumb and first finger of the picking
hand and is used to "pick" the strings. Though most classical
players pick with a combination of fingernails and fleshy
fingertips, the pick is most often used for electric and
steel-string acoustic guitars. Though today they are mainly
plastic, variations do exist, such as bone, wood, steel or tortoise
shell. Tortoise shell was the most commonly used material in the
early days of pick-making, but as tortoises and turtles became
endangered, the practice of using their shells for picks or
anything else was banned. Tortoise-shell picks made before the ban
are often coveted for a supposedly superior tone and ease of use,
and their scarcity has made them valuable.
Picks come in many shapes and sizes. Picks vary from the small jazz
pick to the large bass pick. The thickness of the pick often
determines its use. A thinner pick (between .2 and .5 mm) is
usually used for strumming or rhythm playing, whereas thicker picks
(between .7 and 1.5+ mm) are usually used for single-note lines or
lead playing. The distinctive guitar sound of Billy Gibbons is
attributed to using a quarter or peso as a pick. Similarly, Brian
May is known to use a sixpence coin as a pick. David Persons is
known for using old credit cards, cut to the correct size, as
plectrums.
Thumb picks and finger picks that attach to the finger tips are
sometimes employed in finger-picking styles on steel strings. These
allow the fingers and thumb to operate independently, whereas a
flat pick requires the thumb and one or two fingers to manipulate.
