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
Guitar tunings tuned fifth string can provide a reference to tune the remaining strings by ear. Tuning forks which provide the pitch of the high E string (329.63 Hz) are also common. The guitar is conventionally an equal-tempered instrument. The frets are positioned logarithmically, creating equally-tempered pitches along each string. However, guitarists who tune by ear will typically tune “clean” so that dissonant beating between particular strings is minimized. In this way, open intervals can be more consonant. This is known as just intonation, which is at variance with equal temperament. When the guitar is tuned in this way, open tunings theoretically
