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, cello, and
mandolin. The distinct
open notes are from the
major pentatonic scale on C, which contains only consonant intervals. The C-pentatonic scale omits the open B of standard tuning and all-fifths tuning, which forms a dissonant
second-interval with C. With the 1980s King Crimson, Fripp had used pentatonic harmony in "
Discipline", "
Thela Hun Ginjeet", and "Sartori in Tangier".
Harmonics: Overtones New standard tuning lists four notes (C,G,E,G) from the
harmonic sequence (overtones) for the note C. Persichetti's book influenced Fripp. In new standard tuning • C is the fundamental overtone, • G as a fifth reinforces C, • D as a fifth reinforces G, • A as a fifth reinforces D, • E both as a fifth reinforces A and as the fifth overtone reinforces C, and • G as the sixth overtone reinforces C.
Range . Like all-fifths tuning, Quartal and quintal harmony was stressed from the beginning of Fripp's teaching of
Guitar Craft. Fripp began a 1986 course with these directions: "Now, pick a note from the following series—[it was a series of fourths or fifths].
When you are ready—do not be in any hurry, but
when you are ready play your note, then pick others and play them as the situation demands it. Your first note will be the first
intentional note you have played in a week." It is a challenge to adapt conventional guitar chords to new standard tuning.
Historical background Modern quartal and quintal harmony revives the polyphonic traditions of medieval Europe. Before the
common practice period, European
polyphony emphasized unison intervals and octaves and also perfect fifths. From the Renaissance to 1900, Western symphonic music was
diatonic, emphasizing the
tertian harmony of
major and minor scales, keys, and chords. Much popular music, especially rock, retains diatonic harmony. ==String gauges==
