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
Electric violin and carbon fibres, are used in the build process. They are often seen as "experimental" instruments, being less established than electric guitar or bass. Hence, there are many variations on the standard design, such as frets, extra strings, machine heads, "baritone" strings that sound an octave lower than normal, and sympathetic strings. Luthier Yuri Landman built a 12 string electric violin for the Belgian band DAAU. The strings on this instrument are clustered in four groups of three strings tuned unison creating a chorus. Also the instrument features an extra pickup in the tail piece for extra amplification of string
