Guitar tunings tuning is a tuning in intervals of perfect fifths like that of a mandolin or a violin; 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 would easily break. A variation of all-fifths tuning was used by jazz-guitarist Carl Kress. The bottom four strings are tuned in fifths and the top two strings tuned in thirds resulting in Bb-F-C-G-B-D. This results in tenor banjo formations on
New standard tuning Fripp suggested that Guitar Circle members experiment with an A String (0.007) from Octave4Plus of Gary Goodman; if successful, the experiment could lead to "the NST 1.2", C2G2D3A3E4-A4, according to Fripp. In 2010, Fripp suggested renaming the tuning as "Guitar Craft Standard Tuning or C Pentatonic tuning". The lowest five strings are tuned in perfect fifths from a low C. The first string is a minor third up from the E to a G. Since the lowest five strings are tuned in fifths, guitars with NST can be played with the fingerings for chords and scales used on the violin,
