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
Dropped A tuning Dropped A tuning Dropped A tuning is an alternate tuning for a 7 string guitar where the lowest string is tuned down ("dropped") from the standard B by one whole step to A as follows A1-E2-A2-D3-G3-B3-E4. Also, for a 6 string guitar, dropped A tuning is achieved by tuning all strings down a 4th with the lowest string tuned 1 additional step down as follows A1-E2-A2-D3-F#3-B3. This is a "drop 1" tuning in the key of B (i.e. tune the whole guitar down a perfect fourth from standard tuning, then tune the 6th string a whole step down). As a
