Parts of Guitar

Acoustic Guitar

Some common parts of an acoustic guitar includes:

• Head Stock - The headstock is located at the end of the guitar neck furthest from the body. It is fitted with tuning keys that adjust the tension of the strings, which in turn affects the pitch. Traditional tuner layout is "3+3" in which each side of the headstock has three tuners. Many guitars feature other layouts as well, including six-in-line tuners or even "4+2".
• Nut - The nut is a small strip of bone, plastic, brass, graphite, stainless steel, or other medium-hard material, at the joint where the headstock meets the fretboard. Its grooves guide the strings onto the fretboard, giving consistent lateral string placement. It is one of the endpoints of the strings' vibrating length. It must be accurately cut, or it can contribute to tuning problems due to string slippage.
• Tuning Keys - These keys are used to adjust the tension of the strings. Basically every stringed instrument requires a proper adjustment of all the strings. This adjustment of strings is known as TUNING. You need to tune the guitar before playing. The standard tuning used for the guitar is E-B-G-D-A-E (from string 1 to 6).
• Frets - Frets are metal strips embedded along the fretboard and located at exact points that divide the scale length in accordance with a specific mathematical formula. Pressing a string against a fret determines the strings' vibrating length and therefore its resultant pitch. The pitch of each consecutive fret is defined at a half-step interval on the chromatic scale. Standard classical guitars have 19 frets and electric guitars between 21 to 24 frets.
• Truss Rod - The truss rod is a metal rod that runs along the inside of the neck. It is used to correct changes to the neck's curvature caused by the neck timbers aging, changes in humidity or to compensate for changes in the tension of strings. The tension of the rod and neck assembly is adjusted by a hex nut or an allen-key bolt on the rod, usually located either at the headstock, sometimes under a cover, or just inside the body of the guitar underneath the fretboard and accessible through the sound hole.
• Inlays - Inlays are visual elements set into the exterior surface of a guitar. The typical locations for inlay are on the fretboard, headstock, and on acoustic guitars around the soundhole, known as the rosette. Inlays range from simple plastic dots on the fretboard to intricate works of art covering the entire exterior surface of a guitar.
• Neck - A guitar's frets, fretboard, tuners, headstock, and truss rod, 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, and the ability of the neck to resist bending is important to the guitar's ability to hold a constant pitch during tuning or when strings are fretted. The rigidity of the neck with respect to the body of the guitar is one determinant of a good instrument versus a poor one.
• Neck Joint (Heel) - This is the point at which the neck is either bolted or glued to the body of the guitar. Almost all acoustic guitars have glued necks or set necks, while electric guitars are constructed using both types.
• Strings - Modern guitar strings are manufactured in either metal or organo-carbon material. Instruments utilizing "steel" strings may have strings made of alloys incorporating steel, nickel or phosphor bronze. Classical and flamenco instruments have historically used gut strings but these have been superseded by nylon and carbon-fibre materials. Bass strings for both instruments are wound rather than monofilament.
• Body - The body of an acoustic guitar has a sound hole through which sound is projected. The sound hole is usually a round hole in the top of the guitar under the strings. Air inside the body vibrates as the guitar top and body is vibrated by the strings, and the response of the air cavity at different frequencies is characterized, like the rest of the guitar body, by a number of resonance modes at which it responds more strongly. Most electric guitar bodies are made of wood and include a plastic pick guard. Boards wide enough to use as a solid body are very expensive due to the worldwide depletion of hardwood stock since the 70's, so the wood is rarely one solid piece. Most bodies are made of two pieces of wood with some of them including a seam running down the centre line of the body.
• Bridge - 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 both electric and acoustic 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. 

Electric Guitar

Apart from the parts discussed above the electric guitar have these additional components:

• Pickups - 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.
• 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 pre-amplification 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.
• Vibrato Arm - The Vibrato (pitch bend) unit found on many electric guitars has also had slang terms applied to it, such as "tremolo bar (or arm)", "sissy bar", "wang bar", "slam handle", "whammy handle", and "whammy bar". It is used for a pitch raising effect.

Tuning of Guitar

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.^{[citation needed]}

Tuning

Main article: Guitar tuning

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.

The pitches are as follows:

String	Scientific pitch	Helmholtz pitch	Interval from middle C	Frequency
first	E4	e'	major third above	329.63 Hz
second	B3	b	minor second below	246.94 Hz
third	G3	g	perfect fourth below	196.00 Hz
fourth	D3	d	minor seventh below	146.83 Hz
fifth	A2	A	minor tenth below	110 Hz
sixth	E2	E	minor thirteenth below	82.41 Hz

The table below shows a pitch's name found over the six strings of a guitar in standard tuning, from the nut (zero), to the twelfth fret.

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 in which common scales can be played.^[22] There are also a variety of commonly used alternate tunings – most of which are open tunings that create entire chord voicings without fretting any strings. 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,' the patent for which he owns. 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's tuning to a 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 Bridge

Guitar 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 which allows the player to modulate the pitch moving the bridge up and down. 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 will be 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.

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.
[edit] 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 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. 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.

Body of electric guitar

Body (electric guitar)

 

elements of electric guitars

See also: Solid body

Most electric guitar bodies are made of wood and include a plastic pick guard. Boards wide enough to use as a solid body are very expensive due to the worldwide depletion of hardwood stock since the 70's, so the wood is rarely one solid piece. Most bodies are made of two pieces of wood with some of them including a seam running down the centre line of the body. The most common woods used for electric guitar body construction include maple, basswood, ash, poplar, alder, and mahogany. Many bodies will consist of good sounding but inexpensive woods, like ash, with a "top", or thin layer of another, more attractive wood (such as maple with a natural "flame" pattern) glued to the top of the basic wood. Guitars constructed like this are often called "flame tops". The body is usually carved or routed to accept the other elements, such as the bridge, pickup, neck, and other electronic components. Most electrics have a polyurethane or nitrocellulose lacquer finish. Other alternative materials to wood, are used in guitar body construction. Some of these include carbon composites, plastic material (such as polycarbonate) and aluminium alloys.

Neck joint or 'Heel'

Neck joint or 'Heel'

See also: Set-in neck, Bolt-on neck, and Neck-through
This is the point at which the neck is either bolted or glued to the body of the guitar. Almost all acoustic steel-string guitars, with the primary exception of Taylors, have glued (otherwise known as set) necks, while electric guitars are constructed using both types. Most classical guitars have a neck and headblock carved from one piece of wood, known as a "Spanish heel."

Commonly used set neck joints include mortise and tenon joints (such as those used by CF Martin & Co. guitars), dovetail joints (also used by CF Martin on the D28 and similar models) and Spanish heel neck joints which are named after the shoe they resemble and commonly found in classical guitars. All three types offer stability. Bolt-on necks, though they are historically associated with cheaper instruments, do offer greater flexibility in the guitar's set-up, and allow easier access for neck joint maintenance and repairs.

Another type of neck, only available for solid body electric guitars, is the neck-through-body construction. These are designed so that everything from the machine heads down to the bridge are located on the same piece of wood. The sides (also known as wings) of the guitar are then glued to this central piece. Some luthiers prefer this method of construction as they claim it allows better sustain of each note. Some instruments may not have a neck joint at all, having the neck and sides built as one piece and the body built around it.
