Tunings are described by the particular pitches that are made by notes in
Western music. By convention, the notes are ordered and arranged from the lowest-pitched string (i.e., the deepest bass-sounding note) to the highest-pitched string (i.e., the highest sounding note), or the thickest string to thinnest, or the lowest frequency to the highest. This sometimes confuses beginner guitarists, since the highest-pitched string is referred to as the 1st string, and the lowest-pitched is the 6th string.
Standard tuning defines the string pitches as E (82.41 Hz), A (110 Hz), D (146.83 Hz), G (196 Hz), B (246.94 Hz), and E (329.63 Hz), from the lowest pitch (low E
2) to the highest pitch (high E
4). Standard tuning is used by most guitarists, and frequently used tunings can be understood as variations on standard tuning. To aid in memorising these notes,

The term ''guitar tunings'' may refer to pitch sets other than standard tuning, also called ''nonstandard'', ''alternative'', or ''alternate''.
There are hundreds of these tunings, often with small variants of established tunings. Communities of guitarists who share a common musical tradition often use the same or similar tuning styles.

Some tunings are used for particular songs and may be named after the song's title. There are hundreds of these tunings, although many are slight variations of other alternate tunings.
Several alternative tunings are used regularly by communities of guitarists who share a common musical tradition, such as American folk or Celtic folk music.
The various alternative tunings have been grouped into the following categories:
* dropped

developed a shorthand to specify guitar tunings: one letter naming the note of the open lowest string, followed by the relative fret (half-step) offsets between adjacent strings; in this format, the standard tuning is E55545. This scheme highlights pitch relationships and simplifies comparisons among different tuning schemes.
String gauges
String gauge refers to the thickness and diameter of a guitar string, which influences the overall sound and pitch of the guitar depending on the guitar string used. Some alternative tunings are difficult or even impossible to achieve with conventional guitars due to the sets of guitar strings, which have gauges optimized for standard tuning. With conventional sets of guitar strings, some higher tunings increase the string-tension until playing the guitar requires significantly more finger-strength and stamina, or even until a string snaps or the guitar is warped. However, with lower tunings, the sets of guitar strings may be loose and buzz. The tone of the guitar strings is also negatively affected by using unsuitable string gauges on the guitar.
Generally, alternative tunings benefit from re-stringing of the guitar with string gauges purposefully chosen to optimize particular tunings
by using lighter strings for higher-pitched notes (to lower the tension of the strings) and heavier strings for lower-pitched notes (to prevent string buzz and vibration).
Dropped tunings
A
dropped tuning is one of the categories of alternative tunings and the process starts with standard tuning and typically lowers the pitch of ("drops") one or more strings, almost always the lowest-pitched (E) string on the guitar.

Tuning the lowest string one
tone down, from E to D, allowed these musicians to acquire a heavier and darker sound than in

Open tunings

An open tuning allows the guitarist to play a
chord by strumming the open strings (no strings fretted).
Open tunings may be ''
chordal'' or ''
modal''. In chordal open tunings, the open chord consists of at least three different pitch classes. In a given
key, these are the root note, its 3rd and its 5th, and may include all the strings or a subset. The tuning is named for the base chord when played open, typically a major chord, and all similar chords in the chromatic scale are played by
barring all strings across a single fret.

The strings may be tuned to exclusively present a single interval (all fourths; all fifths; etc.) or they may be tuned to a non-tertian chord (unresolved suspensions such as E–A–B–E–A–E, for example). Modal open tunings may use only one or two pitch classes across all strings (as, for example, some

Popular modal tunings include D Modal (D-G-D-G-B-E) and C Modal (C-G-D-G-B-D).
Lowered (standard)
Derived from standard EADGBE, all the strings are
tuned lower by the same interval, thus providing the same chord positions transposed to a lower key. Lower tunings are popular among rock and heavy metal bands. The reason for tuning down below the standard pitch is usually either to accommodate a singer's vocal range or to get a deeper/heavier sound or pitch. Common examples include:

Regular tunings
In standard tuning, there is an interval of a major third between the second and third strings, and all the other intervals are fourths. This means chords cannot be shifted around the fretboard in the standard tuning E–A–D–G–B–E, which requires four chord-shapes for the major chords. There are separate chord-forms for chords having their
root note on the third, fourth, fifth, and sixth strings. These are called
inversions.

regular tunings have equal intervals between the strings,
and so they have symmetrical scales all along the fretboard. This makes it simpler to translate chords. For the regular tunings, chords may be moved diagonally around the fretboard. The diagonal movement of chords is especially simple for the regular tunings that are repetitive, in which case chords can be moved vertically: Chords can be moved three strings up (or down) in major-thirds tuning, and chords can be moved two strings up (or down) in
augmented-fourths tuning. Regular tunings thus appeal to new guitarists and also to jazz-guitarists, whose improvisation is simplified by regular intervals.
On the other hand, five- and six-string
open chords ("
cowboy chords") are more difficult to play in a regular tuning than in standard tuning. Instructional literature uses standard tuning.
Traditionally a course begins with the hand in
first position, that is, with the left-hand covering frets 1–4.
Beginning players first learn
open chords belonging to the
major keys
C,
G, and
D. Guitarists who play mainly open chords in these three major-keys and their
relative minor-keys (
Am,
Em,
Bm) may prefer standard tuning over many regular tunings,
On the other hand, minor-thirds tuning features many
barre chords with repeated notes, properties that appeal to acoustic-guitarists and beginners.
Major thirds and perfect fourths
Standard tuning mixes a major third (M3) with its perfect fourths. Regular tunings that are based on either major thirds or perfect fourths are used, for example, in jazz.

4 keeps the lowest four strings of standard tuning, changing the major third to a perfect fourth. Jazz musician
Stanley Jordan stated that all-fourths tuning "simplifies the fingerboard, making it logical".
Major-thirds tuning (M3 tuning) is a regular tuning in which the
musical intervals between successive strings are each

Unlike all-fourths and all-fifths tuning, M3 tuning
repeats its octave after three strings, which simplifies the learning of chords and improvisation.
This repetition provides the guitarist with many possibilities for fingering chords.
With six strings, major-thirds tuning has a smaller range than standard tuning; with seven strings, the major-thirds tuning covers the range of standard tuning on six strings.
Major-thirds tunings require less hand-stretching than other tunings, because each M3 tuning packs the octave's twelve notes into four consecutive frets.
The major-third intervals let the guitarist play
major chords and
minor chords with two three consecutive fingers on two consecutive frets.
Chord inversion is especially simple in major-thirds tuning. The guitarist can invert chords by raising one or two notes on three strings—playing the raised notes with the same finger as the original notes. In contrast, inverting triads in standard and all-fourths tuning requires three fingers on a span of four frets.
In standard tuning, the shape of an inversion depends on the involvement of the major-third between the 2nd and 3rd strings.

; other names include "perfect fifths" and "fifths". It has a wide range. Its implementation has been impossible with nylon strings and has been difficult with conventional steel strings. The high B makes the first string very taut, and consequently, a conventionally gauged string easily breaks.

Carl Kress used a variation of all-fifths tuning—with the bottom four strings in fifths, and the top two strings in thirds, resulting in B

4. This facilitated tenor banjo chord shapes on the bottom four strings and plectrum banjo chord shapes on the top four strings. Contemporary New York jazz-guitarist Marty Grosz uses this tuning.

). It is a challenge to adapt conventional guitar-chords to new standard tuning, which is based on all-fifths tuning. Some closely voiced
jazz chords become impractical in NST and all-fifths tuning.
Instrumental tunings
These are tunings in which some or all strings are retuned to emulate the standard tuning of some other instrument, such as a lute, banjo, cittern, mandolin, etc. Many of these tunings overlap other categories, especially open and modal tunings.
Miscellaneous or "special" tunings
This category includes everything that does not fit into any of the other categories, for example (but not limited to): tunings designated only for a particular piece; non-western intervals and modes;
micro- or macro-tones (half sharps/flats, etc.); and "hybrid tunings" combining features of major alternate tuning categories – most commonly an open tuning with the lowest string dropped.
