A guitar chord is a chord, a collection of tones usually sounded together at once, played on a guitar.
Chord voicings designed for the guitar can be optimized for many different purposes and playing styles. Guitar chords can be composed of notes played on only a few strings at a time, whether occurring on adjacent strings or not, or on all the strings.
The instrument is generally very capable and versatile for chording purposes, but it does exhibit some differences with other instruments. Most guitars only have six strings, which means that for the very largest of chord-voicings it's often necessary to drop or omit one or more tones from the chord; this is typically the root or fifth. The layout of notes on the fretboard sometimes demands that the notes in a chord do not run in tonal order, or makes possible a chord which is composed of more than one note of exactly the same pitch. Many chords can be played with exactly the same notes in more than one place on the fretboard.
Guitars can vary both in the number of strings they have, and in the way they're tuned. Most guitars used in popular music have six-strings and are tuned (from the lowest pitched string to the highest): E-A-D-G-B-E. The internal intervals present among adjacent strings in this tuning can be written 5-5-5-4-5 (being mostly perfect fourth intervals plus one major third interval near the middle). Conventionally, the string with the highest pitch (the thinnest) is called the first string, and the string having the lowest pitch is called the sixth.
