New Standard Tuning (NST) is an alternative tuning for the guitar that approximates all-fifths tuning. The guitar's strings are assigned the notes C2-G2-D3-A3-E4-G4 (from lowest to highest); the five lowest open strings are each tuned to an interval of a perfect fifth ; the two highest strings are a minor third apart (E,G). All-fifths tuning is typically used for mandolins, cellos, violas, and violins. On a guitar, tuning the strings in fifths would mean the first string would be a high B, something that was impractical until recently. The NST provides a good approximation to all-fifths tuning. Like other regular tunings, NST allows chord fingerings to be shifted from one set of strings to another. NST's C-G range is wider, both lower and higher, than the E-E range of standard tuning in which the strings are tuned to the open notes E2-A2-D3-G3-B3-E4. The greater range allows NST-guitars to play repertoire that would be impractical, if not impossible, on a standard-tuned guitar. NST was developed by Robert Fripp, the guitarist for King Crimson. Fripp taught the new standard tuning in Guitar-Craft courses beginning in 1985, and thousands of Guitar Craft students continue to use the tuning. Like other alternative tunings for guitar, the NST has provided challenges and new opportunities to guitarists, who have developed music especially suited to NST. Indeed, many NST guitarists have become professional musicians and recording artists. The NST has required greater attention to strings than has standard tuning. String sets for standard tuning have problems being adapted for the New Standard Tuning: With standard string-sets, the lowest string is too loose and the highest string too often snaps under the increased tension. Special sets of NST strings have been available for decades, and some guitarists have assembled NST sets from individual strings.〔(Brian Robinson, composer )〕 ==History== New standard tuning (NST) was invented by Robert Fripp of King Crimson in September 1983. Fripp began using the tuning in 1985 before beginning his Guitar Craft seminars,〔Baldwin, Douglas (November 2007). "Guitar Heroes: How to Play Like 26 Guitar Gods from Atkins to Zappa", edited by Jude Gold and Matt Blackett, ''Guitar Player'', p.111.〕〔 which have taught the tuning to three thousand guitarists.〔 The tuning is (from low to high): C2-G2-D3-A3-E4-G4. The original version of NST was all fifths tuning. However, in the 1980s, Fripp never attained the all fifth's high B. While he could attain A, the string's lifetime distribution was too short. Experimenting with a G string, Fripp succeeded. "Originally, seen in 5ths. all the way, the top string would not go to B. so, as on a tenor banjo, I adopted an A on the first string. These kept breaking, so G was adopted." In 2012, Fripp suggested that Guitar Circle members experiment with an A String (0.007) from Octave4Plus of Gary Goodman;〔(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". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「New standard tuning」の詳細全文を読む スポンサード リンク
