The 5-String Bass: A Beginner's Guide to Strings, Tunings and the Fretboard
The 5-string bass is a regular bass guitar with one extra string: a low B underneath the usual four. That one string gives you deeper notes and more places to play the notes you already know. If you have been curious about it, or someone just handed you one, this guide walks you through the strings, the tuning, how notes sit on the neck and what a bass player actually does in a band.
Five Strings and a Standard Tuning
A 5-string bass has, as the name says, five strings. In standard tuning they are, from the top string to the bottom: B, E, A, D, G.
"Top" and "bottom" here describe how the bass sits on your body. The top string, the one nearest your face, is the thickest and lowest sounding: that is B. The bottom string, nearest the floor, is the thinnest and highest: that is G. It feels backwards at first, but every bassist and guitarist talks this way, so it is worth getting used to.
If you have played a 4-string bass, the good news is that the E, A, D and G strings are exactly the same. The 5-string simply adds a low B above them. Everything you already know still works.
How to Remember It
A silly sentence sticks better than a list of letters. Try: Big Elephants Always Dance Gracefully. Say it a few times while touching each string from thickest to thinnest and it will be locked in by tomorrow.
How the Notes Are Laid Out
Every fret on the bass raises a note by a half step, which is the smallest distance in Western music. On the fretboard, a half step is simply the distance of one fret. Two frets make a whole step.
There are twelve different notes in music, and they repeat. Here is how they run up the B string, one fret at a time:
- Open string: B
- 1st fret: C
- 2nd fret: C#
- 3rd fret: D
- 4th fret: D#
- 5th fret: E
Notice that B to C is only one fret, with no sharp in between. The same thing happens between E and F. Those are the two spots in the musical alphabet where natural notes sit a half step apart. Everywhere else, there is a sharp or flat between them.
The Fifth-Fret Pattern
Look at that list again: the 5th fret of the B string is E, which is the next open string down. This pattern repeats across the whole bass. The 5th fret of the E string is A, the 5th fret of the A string is D, and the 5th fret of the D string is G. Musicians call this distance a fourth, and because every string is tuned a fourth apart, shapes you learn in one spot can be moved to another string and still work.
This even spacing is a gift. It also means you can tune by ear: play the 5th fret on one string and the next open string should sound identical.
The 12th Fret: Starting Over
At the 12th fret, usually marked with a double dot, each string plays its open note again, only higher. This is called an octave: the same note name, but at a higher pitch. Think of it as the same word said in a higher voice. Everything above the 12th fret repeats the layout below it.
Why the Low B Matters
The extra string does two useful jobs. First, it lets you go lower. On a 4-string, the lowest note is open E. The B string gives you D#, D, C# and C below that without retuning anything. Those deep notes add real weight under a band, which is why the 5-string is so common in heavier rock and metal, gospel, and modern pop and worship music.
Second, it gives you more choices for the same notes. That E at the 5th fret of the B string is the same pitch as the open E string. Being able to play a line in one area of the neck, instead of jumping around, makes many bass parts easier and smoother.
One thing to listen for: the low B can sound muddy if you let it ring when you are not using it. Rest your thumb or a spare finger on it to keep it quiet. Learning to mute unused strings is a big part of sounding clean on a 5-string.
What the Bass Does in a Band
The bass is the bridge between rhythm and harmony. Rhythm is the timing and groove, mostly driven by the drums. Harmony is the chords, usually played by guitar or keyboards. The bass connects the two.
Most of the time, a bassist plays the root of each chord, which is the note the chord is named after. If the guitarist plays an A chord, you will often play an A. Then you lock your timing to the kick drum so the band feels like one solid engine. When the bass and kick land together, people start nodding their heads without knowing why.
Fancy fills are fun, but a steady, well-timed part is what gets bassists hired and asked back.
Tunings on the Site
On this site, the 5-string bass is covered in Standard Tuning: B, E, A, D, G. That is the tuning the vast majority of 5-string players use, and it is the one to learn first. Every scale, chord and pattern you explore on the interactive fretboard here is laid out in that tuning, so what you see on screen matches your instrument note for note.
You may hear of players setting up a 5-string differently, but there is no rush. Get comfortable with standard tuning and the fifth-fret pattern, and anything else will make sense later.
Your First Practice Session
Start slow. Play each open string from B down to G, saying its name out loud. Then walk up the B string from the open note to the 5th fret, naming every note, and check that it matches the open E. Repeat on each string. Finally, put on a song you like and try to find just the root notes, one per chord, landing them with the kick drum. Ten minutes a day of this and the neck will start to feel like home.
