Fifths tuning is a non-standard tuning for the double bass, used primarily in classical and jazz music. In this tuning, the double bass is tuned like a cello, but an octave lower.
Although fifths tuning was once the most common double bass tuning in France in the 19th century, standard fourths tuning has since become the most used tuning for the instrument. Fifths has recently been repopularised by a small number of bassists, most notably American Red Mitchell and Canadian Joel Quarrington.
Its advocates say the advantages of fifths tuning are:
- Increased resonance, volume and quality of sound.
- Superior intonation with the rest of the string section due to the uniform tuning.
- Best method of obtaining a low C, without an extension or a fifth string.
- Mostly used by jazz players for the major tenth which can be played easily without a position shift.
