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
Tenor guitar six string guitar. As string tension for any pitch increases with length, some have said these guitars cannot be tuned to the normal CGDA fifths tuning because the A string cannot be tuned to pitch without breaking. However, there are a variety of available methods for addressing this point and bringing the longer-scaled tenor guitar up to standard tuning and pitch: special string sets; strings extracted from a seven string guitar set; etc. Tenor guitars can also be tuned to a reentrant CGDA tuning where the A and sometimes the D are pitched an octave lower. The plectrum guitar is
