Guitar chord for chords having their root note on the third, fourth, fifth, and sixth strings. For a six-string guitar in standard tuning, it may be necessary to drop or omit one or more tones from the chord; this is typically the root or fifth. The layout of notes on the fretboard in standard tuning often forces guitarists to permute the tonal order of notes in a chord. The playing of conventional chords is simplified by open tunings, which are especially popular in folk, blues guitar and non-Spanish classical guitar (such as English and Russian guitar). For example, the typical twelve-bar blues
Bass guitar the strings, and extending the lower string scales allows the string to produce harmonics that are more in tune with the fundamental. To keep proper pitch across all frets in a multi-scale bass guitar, a fanned fret design is applied to the fingerboard. In this case, the frets extend from the neck of the instrument at an angle, in contrast to the standard perpendicular arrangement in standard neck designs, in which the fret spacing is wider for the long scale and closer for the short scale. This is not to be confused with perfect intonation across the whole neck, which
