Among guitar tunings, all-fifths tuning refers to the set of tunings in which each interval between consecutive open strings is a perfect fifth. All-fifths tuning is also called fifths, perfect fifths, or mandoguitar.[1] The conventional "standard tuning" consists of perfect fourths and a single major third between the g and b strings:
All-fifths tuning has the set of open strings
which have intervals of 3 octaves minus a half-step between the lowest and highest string. The conventional tuning has an interval of 2 octaves between lowest and highest string.
All-fifths tuning is a tuning in intervals of perfect fifths like that of a mandolin or a violin. It has a wide range. It was used by jazz guitarist Carl Kress in the form
All-fifths tuning has been approximated with tunings that avoid the high b' replacing it with a g' in the New Standard TuningofKing Crimson's Robert Fripp, which has been taught in Guitar Craft courses.[3][4] Guitar Craft, which has been succeeded by Guitar Circle, has taught Fripp's tuning to 3,000 students.[5]
All-fifths tuning has been approximated with tunings in the Through The Looking Glass Guitar[6] of Kei Nakano, which has been played by him since 2015. This new tuning is like a mirror to all kinds of string instruments including guitar. Also it can adapt to any other tunings of guitar. If tuned to normal guitar for the right handed person, it is able to use for lefty guitar in general, and vice versa.
This tuning combines the wide 5th intervals with the possibility of close intervals that allows the pair of unison 3rd and 2nd strings (A). When playing in unison, this tuning also allow a chorus-like effect similar to the sound that the unison produces in 12 string guitars, but in a much smaller scale.
It was developed to be used with a standard set of strings, for example a hybrid set of 0.9 strings, and without lowering too much the range of the electric guitar. It has a range that starts from two tones lower than the standard E tuning (C2 instead of E2) for the 6st string, but the 1st string is tuned to the same note (E4). It also shares the 4th string tuning (D3) with the E standard tuning.[7]
C-G-D-A-A-E
All-fifths tuning is closely related to all-fourths tuning. All-fifths tuning is based on the perfect fifth (the interval with seven semitones), and all-fourths tuning is based on the perfect fourth (five semitones). The perfect-fifth and perfect-fourth intervals are inversions of one another, and the chords of all-fourth and all-fifths are paired as inverted chords. Consequently, chord charts for all-fourths tunings may be used for left-handed all-fifths tuning.[8]
