A Five-string electric bass adds one lower string to the familiar four-string design. That extra string is usually tuned to low B, extending the instrument’s range below the standard low E. The other strings are commonly tuned E, A, D, and G. Together, they give players access to deeper notes without changing instruments or shifting every passage into a different position.
The added range can be useful in metal, gospel, jazz, and modern pop, where arrangements may call for notes beneath a standard bass’s reach. It can also make certain passages easier to play in one position. Not magic. A fifth string does not automatically make a bassist sound fuller or play better. Players must adapt to a wider neck, altered string spacing, and careful muting. Those details matter: an open low B can rumble through an otherwise clean mix if it rings unintentionally.
This guide explains what distinguishes a five-string bass, how its tuning and construction affect its sound, and what to consider before choosing one. Scale length, neck profile, pickups, and setup all vary between models, so the number of strings alone does not predict comfort or tone. A well-adjusted instrument can feel natural; a poorly matched one may feel like unnecessary work. It is worth questioning the common assumption that more range always means more useful range. For beginners and experienced players alike, the right choice depends on the music, the player’s technique, and how confidently those extra notes can be controlled.
A five-string electric bass typically keeps the familiar E–A–D–G strings and adds a lower B string. This extends the instrument’s range without requiring a player to change position as often. The low B reaches about 30.9 Hz in standard tuning, calculated from the A=440 Hz reference in ISO 16:1975, Standard tuning frequency. More room below. That extra depth suits low-register riffs, extended chord tones, and arrangements that need a fuller bottom end.
The instrument’s role is practical, but not automatic. A low note can add weight to a band mix, yet it may blur if the amp or arrangement lacks definition. The B string also needs deliberate muting: its length can keep vibrating after a note ends. Players moving from four strings may find the neck wider or the string spacing tighter, depending on the instrument’s design. It can take time to adjust.
Tips: Let the low B ring, then mute it deliberately. Check intonation and tuning stability across the neck, especially around the fifth fret. Try a short phrase on both four- and five-string setups; the extra range only helps when the notes stay clear.
| Dimension | Typical Configuration or Fact | Practical Significance |
|---|---|---|
| Definition | An electric bass guitar with five strings, most commonly arranged from low to high as B, E, A, D, and G. | The added low string extends the instrument’s range below the standard four-string E-A-D-G setup. |
| Common tuning | B0–E1–A1–D2–G2 | The strings are generally tuned in perfect fourths, matching the usual interval pattern of a four-string bass. |
| Lowest open note | B0, approximately 30.9 Hz | Provides low notes useful for extended-range bass lines and arrangements in lower keys. |
| Other open-string notes | E1 (about 41.2 Hz), A1 (55.0 Hz), D2 (about 73.4 Hz), and G2 (about 98.0 Hz) | These are the same four open notes found on a conventionally tuned four-string bass. |
| Compared with a four-string bass | Adds one lower string while retaining the familiar E-A-D-G strings. | A player can reach lower pitches without retuning the whole instrument or changing to a different bass. |
| Neck and string spacing | The neck and nut accommodate five strings; spacing varies by instrument design. | The wider string set may take some adjustment for players used to four strings, particularly when muting strings cleanly. |
| Common musical roles | Used in many styles, including rock, metal, jazz, gospel, funk, and contemporary worship. | The low B can reinforce a song’s lower register, while the familiar upper four strings support standard bass parts. |
| Playing considerations | Requires clear muting and consistent technique across all five strings. | Good muting helps prevent unused strings from ringing, especially during low-register passages. |
Note: B-E-A-D-G is the most common five-string tuning, but alternate tunings and instrument specifications vary. The listed frequencies are approximate equal-tempered pitches at standard concert pitch.
A five-string electric bass extends the familiar four-string range with a low B string. In standard tuning, the strings run B₀–E₁–A₁–D₂–G₂, from lowest to highest. Their open-string frequencies are approximately 30.87, 41.20, 55.00, 73.42, and 98.00 hertz. These figures use equal temperament, the common system that divides octaves into twelve equal steps.
The reference point is well documented: ISO 16:1975 sets standard musical pitch at A₄ = 440 hertz. The other frequencies follow from that reference, with each octave doubling or halving the frequency. On the bass, the low B produces a deep vibration you can feel against a cabinet or floor. Its longer wavelength also makes clean note definition harder in some rooms. Small details matter. Tune each open string carefully, then check a fretted note; finger pressure can pull its pitch sharp. I still find the low B less forgiving than the upper strings. That is partly the instrument, and partly my setup. A tuner may show the right number, while a rushed pluck makes the reading wobble.
A standard five-string bass adds a low B string beneath the usual E string. Its open note is B0, with a fundamental frequency near 30.87 Hz. A four-string bass’s lowest open note, E1, is about 41.20 Hz. That difference is audible in some settings, but it is not always obvious.
B0 vibrates more slowly and reaches lower than E1 by a perfect fourth. On a large speaker, a sustained low B can feel broad and weighty, while the E often sounds more defined. Small speakers may reproduce the upper harmonics but barely convey the fundamental. That can make the note seem thinner than expected. Room acoustics matter, too.
The extra range is useful for matching lower arrangements without retuning, though it asks more from the instrument and player. Low notes can become muddy if they ring too long or sit too loudly in a mix. A careful setup helps the B string feel even beside the others, but setup cannot fix every instrument’s response. I still find the lowest notes less satisfying on some stages; the number alone does not tell the whole story.
A five-string bass adds a low B string, but its usefulness depends on how clearly that note speaks. Scale length—the distance from the nut to the bridge—helps shape string tension and feel. Many instruments use a 34-inch scale; some use 35 inches. The extra inch may help the low string feel firmer at the same tuning and string gauge. It can also make the fret spacing slightly wider. That difference is noticeable.
On a 34-inch bass, the low B can feel comfortable under the fretting hand, especially during quick position shifts. Some players find its response less defined, though. A 35-inch scale may give the string a tauter feel and a clearer attack, useful when playing low notes that need to stand apart in a dense mix. Results vary. String choice, setup, construction, and playing touch all matter, so scale length alone cannot guarantee a tight sound.
Try both if you can. Play a low B at the fifth fret, then compare its volume and sustain with the open string. Notice whether the longer reach feels natural near the first few frets. I have found that a firmer string can feel reassuring, but that preference is not universal. Even a careful comparison has limits: different setups can muddy the picture. A well-adjusted instrument matters more than the number on a spec sheet.
A five-string bass adds a low B string, but the neck does not simply become wider by a fixed amount. Published professional instrument specifications commonly show nut widths around 44–48 mm and bridge string spacing near 16–19 mm. These are practical reference ranges, not a universal standard. The nut is the narrow end of the neck; its spacing affects how crowded the strings feel near the first fret. Feel matters. A wider nut can give larger fingers more room, while a narrower one may suit players moving from four strings.
Bridge spacing changes the picture further. With roughly 16 mm between strings, the right hand has less room for fingerstyle plucking, but the fretting hand may find stretches easier. Around 19 mm, strings feel more separated, though wide reaches can become tiring. Small differences count. Neck thickness and shoulder shape also affect comfort, so nut width alone cannot predict the fit. When comparing basses, measure the center-to-center distance between strings at both the nut and bridge, then test a low-B passage across the neck. Published dimensions help narrow a choice, but they cannot capture hand size, technique, or playing fatigue. That rule is imperfect; even familiar measurements can feel wrong after a long rehearsal.
It keeps E–A–D–G and adds a low B string. More room below.
In standard tuning, its open note reaches about 30.9 Hz. That is a deep rumble.
It can support low riffs, extended chord tones, and fuller arrangements. It does not automatically improve a mix.
The note may blur if the amp or arrangement lacks definition. Careful muting helps keep it tidy.
The neck may feel wider, and the strings may sit closer together. It can take time.
Often, yes. Many basses use a 34-inch scale; some use 35 inches. The longer scale may feel firmer.
No. String choice, setup, construction, and touch also matter. A spec sheet cannot tell the whole story.
Play the low B at the fifth fret, then compare it with the open string. Listen for volume and sustain.
Notice the reach near the first frets and check tuning across the neck. Different setups can muddy the comparison.
A Five-string electric bass extends the range of a standard four-string bass by adding a low B string. Its common tuning, from lowest to highest, is B₀–E₁–A₁–D₂–G₂, giving players access to deeper notes without changing the familiar tuning of the other four strings. The low B₀ has a frequency of about 30.87 Hz, compared with approximately 41.20 Hz for the low E₁ on a four-string bass. This extra range can support lower musical passages and offer more options for moving around the fretboard.
The longer strings and larger neck help accommodate the additional low string. Many five-string basses use a 34-inch scale, while some have a 35-inch scale to help the low string feel firmer and respond clearly. Neck width, nut design, and spacing between strings also affect comfort and playability. These dimensions vary, so players can choose an instrument whose layout suits their hands and preferred playing style.
