Here's a bestessays about guitar tunings are differing pitch arrangements of open (unfretted) strings used for the guitar. Many arrangements are possible, some of the most popular are detailed below.

Notes in standard tuning.
By far the most popular tuning on a 6-string guitar, it consists of the following notes.
String Note
Frequency 1 (Highest)
e' 329.60 Hz 2
b 246.90 Hz 3
g 196.00 Hz 4
d 146.80 Hz 5
A 110.00 Hz 6 (Lowest)
E 82.40 Hz
The pitches referred to above are referenced standard pitch (a' = 440.0 Hz.). In some regions of Europe, especially Germany and Poland, the B natural is indicated with the letter H: in music notation, H is B♮ (B natural) and B is B♭ (B flat).
- The guitar, as conventionally fretted, is an equal tempered instrument.
This pattern can also be denoted as E-A-d-g-b-e'. (See note for an explanation of the various symbols used in the above table and elsewhere in this article.)
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. The separation of the first (e') and second (b) string, as well as the separation between the third (g), fourth (d), fifth (A), and sixth (E) strings by a five-semitone interval (a perfect fourth) allows notes of the chromatic scale to be played with each of the four fingers of the left hand controlling one of the first four frets (index finger on fret 1, little finger on fret 4, etc.). It also yields a symmetry and intelligibility to fingering patterns.
The separation of the second (b), and third (g) string is by a four-semitone interval (a major third). Though this breaks the fingering pattern of the chromatic scale and thus the symmetry, it eases the playing of some often-used chords and scales, and it provides more diversity in fingering possibilities.
The chromatic (equal tempered) musical scale and the natural musical scale have note pitches that are very similar. The natural musical scale uses natural harmonic pitches. For example, the A note has harmonics pitches for the D and E notes. The guitar fretboard can approximately accommodate to tuning to the chromatic or natural musical scale by adjusting the intonation by a little. Intonation is tuning of the fret notes to other fret notes so that most of the fretboard pitches are tuned to the pitches of the musical scale of a particular guitar string. Intonation tuning is done by adjusting the string lengths at the bridge. The open string note of a particular string is kept constant so that when adjusting the string length, most of the fretboard pitches are closely matched to the pitches of the musical scale for this string.
