Getting to Five-String (B Standard) from standard
What each string does relative to standard Bass tuning. Work down the list in order — retuning one string changes the neck tension slightly, so go back and re-check the first string once you've finished.
| String | Standard | This tuning | Change |
|---|---|---|---|
| 5 | — | B0 | added string |
| 4 | E1 | E1 | unchanged |
| 3 | A1 | A1 | unchanged |
| 2 | D2 | D2 | unchanged |
| 1 | G2 | G2 | unchanged |
Why players use Five-String (B Standard)
A low B string added below standard, extending downward range by five semitones without detuning anything. The alternative to drop tunings for players who need the low notes but want standard fingerings intact.
The interval structure of Five-String (B Standard)
Adding a low B below the standard four extends downward range by five semitones while leaving every existing string exactly where it was — the fundamental difference from a drop tuning, which buys low notes by moving something. All five strings remain in perfect fourths, so positional fingerings extend onto the new string without exception. The B sits near 31 Hz, below what most monitoring reproduces, so its practical use is often the notes higher up the B string rather than the open string itself, which conveniently puts otherwise awkward passages under the hand.
Worth knowing: B0 is about 31 Hz — below the fundamental range of most monitors, so what you hear live is often the harmonics rather than the note itself.
