Chord is a combination of three or more varied notes which sound simultaneously. Guitar chord is a collection of tones sounding together while playing on guitar, which is a type of string instrument. The voicing of chord designed specially for the guitar could be perfected for different playing styles and purposes. Only on few strings, notes of guitar chords could be composed at a single time irrespective of whether it occurs on all strings or on adjacent strings.

Guitar is generally a versatile instrument and is entirely capable for chording compositions and it stands differentiated from other instruments as well. Mostly guitars have only six strings and the fifth or the root, being the largest of chord-voicing is often needed to be dropped else omitted. The fretboard, also known as the finger board of most of the stringed instruments, have notes on it, demanding the chord notes not composed in a tonal order or ensures that a chord is composed of the same pitch with more than one note. Also, with the same set of notes, much number of chords can be played on different places on the fretboard.

Guitars vary both in the way they are been tuned as well as the number of strings they possess. They are tuned from the lowest pitched string to the highest pitched string. Mostly in popular music, the guitars being used have six strings and tuned as E-A-D-G-B-E. The adjacent string's tuning can be composed as 4-4-4-3-4 in proper internal intervals. Formally, the highest pitched string, which is also the thinnest, is known as the ‘first string', while the lowest pitched string is known as ‘sixth'

Representation of Guitar chords are done through tablature and are often referred as tab – a standard musical notation or chord diagrams. Also, fret numbers are given to each chord by the way of shorthand for the chord diagrams. The intervals within the strings are taken a great advantage by the guitar chords and are ‘perfect fourths' with the exception of interval between the ‘second' and ‘third' strings, ending to be a ‘major third'.

Important chords comprise a note, a root note, a ‘perfect fifth' ahead of root and a ‘major third' above the root. Minor chords are similar to major chords, the main difference being having a ‘minor third' in place of ‘major third'. When the ‘bass note' is not the ‘root note', the chord is slashed back and a seventh chord is constructed when a fourth note is added to the main triad. Also, power chords comprise only a fifth and a root note.

While considering the fact, Guitar Chords stay in close connection with music lovers and it can be greatly assisted with its varied forms of chords.
