Double bass fifths point out that all of the other orchestral strings are tuned in fifths (violin, viola, and cello), so this puts the bass in the same tuning approach. Fifth tuning provides a bassist with a wider range of pitch than a standard E–A–D–G bass, as it ranges (without an extension) from C to A. Some players who use fifths tuning who play a five-string bass use an additional high string (thus, from lowest to highest: C–G–D–A–E). Some fifth tuning bassists who only have a four string instrument and who are mainly performing soloistic works use the G–D–A–E tuning, thus omitting
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
