Capo plays a B note for any capo position at or below the seventh fret), and thus a performer does not need to adjust for or relearn the entire fretboard as they might with retuning. The scale length of the strings of an instrument affects the timbre of the strings, and thus the use of a capo may alter the tone of the instrument. Musicians also use capos to bring a guitar tuned below standard up to standard tuning. Manufacturers sometimes recommend tuning a twelve-string guitar a whole-step or more below standard to offset the additional stress of the additional strings.
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
