For the regular tunings, chords may be moved diagonally around the fretboard. This makes it simpler to translate chords into new keys. Regular tunings have symmetrical scales all along the fretboard. having six semitones in its interval, augmented-fourths tuning repeats its notes after two (12/6) strings.having four semitones in its interval, major-thirds tuning repeats its open notes after three (12/4) strings.having three semitones in its interval, minor-thirds tuning repeats its open notes after four (12/3) strings.The regular tunings whose number of semitones s divides 12 (the number of notes in the octave) repeat their open-string notes (raised one octave) after 12/ s strings: For example, 5 semitones ( perfect fourth): All-fourths tuning,.4 semitones ( major third): Major-thirds tuning,.3 semitones ( minor third): Minor-thirds tuning,.In fact, the class of each regular tuning is characterized by its musical interval as shown by the following list: In contrast, regular tunings have constant intervals between their successive open-strings. Working around the irregular third of standard tuning, guitarists have to memorize chord-patterns for at least three regions: The first four strings tuned in perfect fourths two or more fourths and the third and one or more initial fourths, the third, and the last fourth. With standard tuning, and with all tunings, chord patterns can be moved twelve frets down, where the notes repeat in a higher octave.įor the standard tuning, there is exactly one interval of a third between the second and third strings, and all the other intervals are fourths. Standard and alternative guitar-tunings: A review This article's descriptions of particular regular-tunings use other sources also. Sethares's 2001 chapter Regular tunings (in his revised 2010–2011 Alternate tuning guide) is the leading source for this article. The class of regular tunings has been named and described by Professor William Sethares. Left-handed guitarists may use the chord charts from one class of regular tunings for its left-handed tuning for example, the chord charts for all-fifths tuning may be used for guitars strung with left-handed all-fourths tuning. On the other hand, some conventional major/minor system chords are easier to play in standard tuning than in regular tuning. Regular tunings thus often appeal to new guitarists and also to jazz-guitarists, as they facilitate key transpositions without requiring a completely new set of fingerings for the new key. 7 semitones ( perfect fifth): All-fifths tuningįor the regular tunings, chords may be moved diagonally around the fretboard, as well as vertically for the repetitive regular tunings (minor thirds, major thirds, and augmented fourths).6 semitones ( augmented fourth, tritone, or diminished fifth): Augmented-fourths tuning,.5 semitones (perfect fourth): All-fourths tuning,.4 semitones (major third): Major-thirds or Augmented tuning,.3 semitones (minor third): Minor-thirds, or Diminished tuning.In contrast, regular tunings have constant intervals between their successive open-strings: Between the open-strings of the standard tuning are three perfect-fourths (E–A, A–D, D–G), then the major third G–B, and the fourth perfect-fourth B–E. The standard tuning defines the string pitches as E, A, D, G, B, and E. By convention, the notes are ordered from lowest to highest. Tunings can be described by the particular pitches that are denoted by notes in Western music. Guitar tunings assign pitches to the open strings of guitars. Makes it difficult to play music written for standard tuning.Īmong alternative guitar-tunings, regular tunings have equal musical intervals between the paired notes of their successive open strings. Provides new material for improvisation by advanced guitarists The chromatic circle lists the twelve notes of the octave. For regular guitar-tunings, the distance between consecutive open-strings is a constant musical-interval, measured by semitones on the chromatic circle.
