Double bass the "old" German method sounded an octave below where notation except in the treble clef, where the music was written at pitch. The double bass is generally tuned in fourths, in contrast to other members of the orchestral string family, which are tuned in fifths (for example, the violin's four strings are, from lowest-pitched to highest-pitched: G-D-A-E). The standard tuning (lowest-pitched to highest-pitched) for bass is E–A–D–G, starting from E below second low C (concert pitch). This is the same as the standard tuning of a bass guitar and is one octave lower than the four lowest-pitched strings of standard
Dropped A tuning result, it uses the same fingering as drop D tuning and drop C tuning. An alternate dropped A tuning utilizes a guitar tuned to E Standard with the 6th string dropped to a low A, resulting in AADGBE with the 6th and 5th strings an octave apart. Another variation of this tuning is AEADGB, which imitates a 7 on a six-string, excluding the high E. Another dropped A tuning is AGCFAD ("drop perfect fourth in the key of the D", i.e. whole guitar is tuned down one step, then the lowest string is dropped to A). Dropped A tuning Dropped
