Guitar
Anatomy
The overall design of the
guitar, although it has evolved much over the decades, still remains entirely true to tradition. Almost every
guitar will have a number of clearly recognizable parts. We will start at the top of the guitar and work
downwards. 
Headstock –
This is the entire top part of the guitar neck, which incorporates the tuning pegs or machine heads, and is
usually attached to the neck at a slight angle.
Machine heads –
Or some other form of tuning peg, are incorporated into the headstock, with the excess string wound around
them, and are used to bring the strings up to
tension(tune).
Nut – This is
the cross bar, which has slots in it, in which the strings sit, just before they run up into the
headstock.
Neck – The long
part of the guitar, which runs from the headstock down to the body,joining the body at the 12th or 14th fret
usually.
Fret board –
The front of the neck,physically fingered when playing the guitar.
Frets – Wire
bars running across the fret board, which when responding to the pressure of your left hand(for right handed
players),changes notes accordingly.
Strings –
Nylon, gut or steel wires, sometimes wound, which are fingered and plucked, or strummed, to produce
sound.
Heel or
Neckjoint – This is the reinforced section of the guitar, where the neck joins the
body.
Body – Which
incorporates the sides and the back of the guitar, and has the soundboard on
top.
Soundboard –
The top of the guitar body, the front face, which is responsible for initiating resonance in an acoustic guitar, by picking up the vibration of the
strings via the bridge, and transferring it into the hollow body.
Pickguard – A
hard, usually plastic plate attached to the soundboard, which protects it from being damaged or worn by a
person using a pick.
Soundhole –
Only acoustic or semi-acoustic guitars have a soundhole, think of it as the speaker, this is where the
resonating sound escapes from to be heard.
Endpin- Where
the strap is attached and often a cord is plugged in here for
amplification.
Saddle or
Bridge – The part of the guitar, which anchors the strings at the bottom end. Upon an acoustic
guitar, the saddle is responsible for initiating resonance with the
soundboard.
Electric Guitar Components
Electric guitars contain several
parts not found on acoustic guitars.
Pickups – These
are small magnetic devices that can pick up the vibrations of the strings, and convert these vibrations into
a measurable electrical current. This electrical current is then amplified
externally.
Selector
switches – When a multi-pickup setup is used, the selector switch allows the musician to select
which pickup, or combination of pickups, they require to be active.
Volume and tone
controls– Simple knobs to adjust the volume and tone of the
guitar.
Equalization –
Some more modern guitars may contain a basic equalizer setup, allowing the tone to be shaped before being
amplified. Note; some acoustic-electric guitars may have on-board
equalizers.
Tremolo –
Sometimes called the whammy bar, or vibrato arm, this piece of equipment allows the player to gently modulate
the strings by changing the tension of them using their right hand.
