Guitar Tuner D Standard

[Melany Odeh]

Guitar tunings are the assignment of pitches to the open strings of guitars, including classical guitars, acoustic guitars, and electric guitars. 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.[1] 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.

The term guitar tunings may refer to pitch sets other than standard tuning, also called nonstandard, alternative, or alternate.[3] 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.

The guitar is a transposing instrument; that is, music for guitars is notated one octave higher than the true pitch. This is to reduce the need for ledger lines in music written for the instrument, and thus simplify the reading of notes when playing the guitar.[5]

Standard tuning provides reasonably simple fingering (fret-hand movement) for playing standard scales and basic chords in all major and minor keys. Separation of the second (B) through fifth (A) strings being tuned in minor 3rds and second (e) following the low (E) string as the separation being tuned in 5ths, and creating as by a five-semitone interval (a perfect fourth) allows the guitarist to play a chromatic scale with each of the four fingers of the fretting hand controlling one of the first four frets (index finger on fret 1, little finger on fret 4, etc.) only when the hand is in the first position.

The open notes of the second (B) and third (G) strings are separated by four semitones (a major third). This tuning pattern of (low) fourths, one major third, and one fourth was inherited by the guitar from its predecessor instrument, the viol. The irregular major third breaks the fingering patterns of scales and chords, so that guitarists have to memorize multiple chord shapes for each chord. Scales and chords are simplified by major thirds tuning and all-fourths tuning, which are regular tunings maintaining the same musical interval between consecutive open string notes.[3]

Alternative ("alternate") tuning refers to any open string note arrangement other than standard tuning. These offer different kinds of deep or ringing sounds, chord voicings, and fingerings on the guitar. Alternative tunings are common in folk music. Alternative tunings change the fingering of common chords when playing the guitar, and this can ease the playing of certain chords while simultaneously increase the difficulty of playing other chords.

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.[6] Several alternative tunings are used regularly by communities of guitarists who share a common musical tradition, such as American folk or Celtic folk music.[7]

Joni Mitchell 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.[16] This scheme highlights pitch relationships and simplifies comparisons among different tuning schemes.

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.[17] 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[18] 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).

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") only a single string, almost always the lowest-pitched (E) string on the guitar.

The drop D tuning is common in electric guitar and heavy metal music.[19][20] The low E string is tuned down one whole step (to D) and the rest of the strings remain in standard tuning. This creates an "open power chord" (three-note fifth) with the low three strings (DAD).

In the mid-1980s, three alternative rock bands, King's X, Soundgarden and Melvins, influenced by Led Zeppelin and Black Sabbath, made extensive use of drop D tuning. While playing power chords (a chord that includes the prime, fifth and octave) in standard tuning requires a player to use two or three fingers, drop D tuning needs just one, similar in technique to playing barre chords It allowed them to use different methods of articulating power chords (legato for example) and more importantly, it allowed guitarists to change chords faster. This new technique of playing power chords introduced by these early grunge bands was a great influence on many artists, such as Rage Against the Machine and Tool. The same drop D tuning then became common practice among alternative metal acts such as the band Helmet, who used the tuning a great deal throughout their career and would later influence much alternative metal and nu metal bands.[22]

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.[23] Open tunings are common in blues and folk music.[24] These tunings are frequently used in the playing of slide and lap-slide ("Hawaiian") guitars, and Hawaiian slack key music.[23][25] A musician who is well known for using open tuning in his music is Ry Cooder, who uses open tunings when playing the slide guitar.[24]

Open tunings often tune the lowest open note to C, D, or E and they often tune the highest open note to D or E; tuning down the open string from E to D or C avoids the risk of breaking strings, which is associated with tuning up strings.

Any kind of chordal tuning can be achieved, simply by using the notes in the chord and tuning the strings to those notes. For example, Asus4 has the notes A, D, E. By tuning the strings to only those notes, it creates a chordal Asus4 tuning.

Cross-note tunings include a minor third, so giving a minor chord with open strings. Fretting the minor-third string at the first fret produces a major-third, so allowing a one-finger fretting of a major chord.[41] By contrast, it is more difficult to fret a minor chord using an open major-chord tuning.

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.[43] Common examples include:

D Tuning, also called One Step Lower, Whole Step Down, Full Step or D Standard, is another alternative. Each string is lowered by a whole tone (two semitones) resulting in D-G-C-F-A-D. It is used mostly by heavy metal bands to achieve a heavier, deeper sound, and by blues guitarists, who use it to accommodate string bending and by 12-string guitar players to reduce the mechanical load on their instrument. Among musicians, Elliott Smith was known to use D tuning as his main tuning for his music. It was also used for several songs on the Velvet Underground's album The Velvet Underground & Nico. Metal band Megadeth has also been using this tuning since their album Dystopia to facilitate frontman Dave Mustaine's age and voice after his battle with throat cancer.

In contrast, regular tunings have equal intervals between the strings,[46] 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.

Major-thirds tunings require less hand-stretching than other tunings, because each M3 tuning packs the octave's twelve notes into four consecutive frets.[57][60] The major-third intervals let the guitarist play major chords and minor chords with two three consecutive fingers on two consecutive frets.[61]

All-fifths tuning is a tuning in intervals of perfect fifths like that of a mandolin or a violin; other names include "perfect fifths" and "fifths".[64] 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.
