Quick Overview
Standard bass guitar tuning (E A D G) is the most common tuning used on 4-string electric bass.
In standard tuning, the four strings are tuned to E A D G, from lowest-pitched string to highest.
Unlike guitar, every pair of adjacent bass strings is tuned a perfect fourth apart, with no exceptions. That even spacing is part of why chord shapes and scale patterns on bass move consistently across the neck.
Many bassists also play in drop tunings, such as drop D, drop C, or drop B, to match a guitarist tuning down or to get a deeper low end. 5-string and 6-string basses extend the range further with an added low B string, or both a low B and a high C string.
Names like "drop C" and "drop B" aren't perfectly standardized across every player and instrument. In this guide, we define each tuning explicitly by its note names, so there's no ambiguity about what we mean when we use a given name.
Understanding how these tunings relate to each other, and choosing the right string gauge and construction for each, can help you maintain tension and tuning stability no matter what you're tuned to.
Quick Answer
Standard 4-string bass tuning is E A D G.
From lowest string to highest string, the notes are:
E – A – D – G
In this guide, when we refer to Drop D on a 4-string bass, we mean D A D G. When we refer to Drop C, we mean C G C F. When we refer to Drop B, we mean B F# B E. 5-string basses commonly use B E A D G, adding a low B string below standard tuning, and 6-string basses commonly use B E A D G C, adding both a low B and a high C.
What Is Standard Bass Tuning (E A D G)?
Standard bass tuning refers to the default tuning used on most 4-string electric basses.
The four strings are tuned to the following notes:
E A D G
From lowest (thickest) string to highest (thinnest).
Every interval between adjacent bass strings is a perfect fourth. That's different from standard guitar tuning, which has one major-third interval between the G and B strings. Because bass tuning has no exception, scale and chord shapes shift consistently by string without needing to adjust for an odd interval.
Standard bass tuning also provides a useful reference point for understanding common alternate tunings such as Drop D and the lower drop tunings covered below. If you play guitar as well, our Standard Guitar Tuning and Complete Guide to Drop Tunings for Guitar cover the same relationships on six strings.
Standard Bass Tuning Chart
Below is a quick reference chart for the notes used in standard 4-string bass tuning.
| String | Note | Description |
|---|---|---|
| 4th | E | Low E string |
| 3rd | A | A string |
| 2nd | D | D string |
| 1st | G | High G string |
Standard 4-string bass tuning sits exactly one octave below the bottom four strings of a guitar in standard tuning.
Standard Bass Tuning vs. Drop Tunings
Many alternate bass tunings are built from standard tuning the same way alternate guitar tunings are.
| Tuning | Notes |
|---|---|
| Standard | E A D G |
| Drop D | D A D G |
| Drop C | C G C F |
| Drop B | B F# B E |
Drop tunings change the lowest string relative to the strings above it. In Drop D, only the lowest string is lowered from standard tuning. Lower drop tunings, such as the C G C F and B F# B E examples shown here, also lower the remaining strings while preserving that same drop relationship between the lowest string and the rest of the set.
How to Tune a Bass to Standard Tuning
There are a few reliable ways to get a bass in tune.
Using a Bass Tuner
One of the easiest ways to tune a bass is with an electronic tuner. A digital clip-on tuner attaches to the headstock and detects vibration directly, making it a convenient option for practice, rehearsals, and other situations where an acoustic reference pitch may be difficult to hear. Pedal, plug-in, and rack tuners are also accurate options; which one makes sense usually comes down to where and how you're playing.
Tune each string to the following notes:
E A D G
Tuning Using the 5th Fret Method
Another common method tunes the bass relative to itself once one string is set.
1. Tune the low E string using a tuner or another reliable reference pitch.
2. Press the 5th fret on the E string and match it to the open A string.
3. Press the 5th fret on the A string and match it to the open D string.
4. Press the 5th fret on the D string and match it to the open G string.
Once the low E string is set correctly, the rest of the bass can be tuned relative to that single pitch.
Choosing the Right Strings for Standard Bass Tuning
Standard tuning works with a wide range of string gauges. A common, versatile starting point for a 4-string bass in standard tuning is around .045–.105, but no single gauge is universally prescribed. Scale length, construction, and how you like a string to feel under your hands all factor into what's actually right for your bass.
Tension itself depends on gauge, pitch, scale length, and construction together, not gauge alone. That's why two sets with the same listed gauge can still feel different from one bass to another.
A traditional nickel-plated roundwound like Power Wound Nickel is a versatile option at standard tuning. Foundations Nickel uses a smaller core wire designed for a more flexible feel with lower tension, and stainless options like Power Steel Stainless or Foundations Stainless are worth a look if you want more upper-frequency content.
If you're unsure which gauge fits your bass and playing style, our What Gauge Bass Strings Should I Use? guide walks through the factors involved, and What Length Bass Strings Do I Need? covers scale length and fitment.
How String Gauge Affects Bass Tuning
When a string is tuned down without changing anything else, it loses tension. Lower tension can make a string feel looser under your fingers and, in some cases, lead to reduced clarity or fret buzz.
Moving to a heavier gauge when tuning down restores some of that lost tension, which is why drop tunings and lower tunings often call for a heavier string than standard tuning on the same bass. This is a tension effect, not a tone or sustain guarantee. String tension and feel are affected by several factors beyond gauge alone, including core diameter, construction, material, scale length, and pitch, which is why we recommend thinking about the complete string rather than the gauge number by itself.
Because of all those variables, we can't responsibly point to one exact gauge as the correct choice for Drop D, Drop C, or Drop B on every bass. The right gauge for a given tuning depends on your target pitch, your bass's scale length, the string's construction, the feel you're after, and how your instrument is set up.
It's also worth remembering that gauge and string length aren't the same thing. A heavier string still needs the correct winding length for your bass, particularly on 5-string, 6-string, or extended-scale instruments. Our What Length Bass Strings Do I Need? guide covers scale length and fitment.
Drop D, Drop C, and Drop B Bass Tuning
Bassists move to drop tunings for a few different reasons: to match a guitarist who's tuned down, to extend the low end of a song, or simply because a lower tuning fits the part they're playing. None of these tunings is required for any particular genre, and plenty of heavy, low-end-focused music is played in standard tuning as well.
Drop D Bass Tuning
Drop D lowers only the E string a whole step, to D A D G. Because only one string changes, drop D is a common entry point for players who want an occasional lower note without retuning the whole bass.
Drop C Bass Tuning
Drop C lowers all four strings a whole step from standard tuning, then lowers the lowest string another whole step, giving C G C F. Because every string is under less tension than in standard tuning, a heavier gauge is worth considering to keep the set feeling and responding the way you expect.
Drop B Bass Tuning
For the Drop B tuning used in this guide, the strings are tuned to B F# B E, one semitone (a half step) below the C G C F Drop C tuning above. At this tuning, gauge and construction both start to matter more for keeping the lowest string from feeling loose or indistinct.
5-String and 6-String Bass Tuning
5-string basses commonly use B E A D G, adding a low B string below standard tuning. This gives players access to a lower range without retuning the other four strings away from standard. Some players set up a 5-string with a high C instead, as E A D G C, depending on the range they need.
6-string basses commonly use B E A D G C, adding both a low B below standard and a high C above it, extending the range in both directions.
Because the low B is tuned to a lower pitch than the other strings, gauge, scale length, and string construction all influence its tension, feel, and response. We'll cover 5-string and 6-string gauge selection in more depth in a dedicated guide.
Do You Need a Bass Setup After Changing Tunings?
It depends on what's changing. A small, temporary shift, like moving from standard tuning to Drop D on the same strings, often doesn't require a setup if the bass continues to play and intonate properly.
Larger or more permanent changes, whether that's a lower tuning, a heavier gauge, or both, can affect neck relief, action, intonation, and how the strings sit in the nut and bridge. Moving to a noticeably heavier gauge in particular can create fitment issues if the nut slots are cut too narrow for the new strings.
Changing string gauge or tension can also shift intonation enough to need adjustment, independent of whether the tuning itself changed. If you're unsure whether your bass needs attention after a tuning or gauge change, having it checked by a qualified guitar or bass technician is the most reliable way to find out.
Construction and Material Considerations for Different Tunings
Tuning is only one factor in how a bass feels and sounds. Construction and material matter at every tuning, not just lower ones.
If additional upper-frequency content, attack, and note definition are priorities in a lower tuning, a roundwound construction, like Power Wound Nickel or Power Steel Stainless, is worth considering. Flatwound strings, like Power Flat Flat Wound, remain a legitimate option at lower tunings too, when their smoother, more fundamental-focused response and reduced finger noise are what you're after. Our Roundwound vs. Flatwound vs. Semi-Flat and Nickel vs. Stainless Steel guides cover both comparisons in more depth.
Final Tips for Tuning Your Bass
Whichever tuning you play in, a few habits help keep your bass sounding and feeling the way you expect.
Check your tuning regularly. Temperature changes, playing, and changes in the instrument itself can all affect tuning over time. If you move between standard and a drop tuning often, expect to spend a little more time re-tuning and let the bass settle before you rely on it being perfectly in pitch.
If you switch tunings frequently and find your current strings feel too loose or too stiff for the tuning you're in, that's usually a sign it's worth reconsidering gauge or construction, or having your setup checked, rather than assuming the tuning itself is the problem.
Frequently Asked Questions About Bass Tuning
What is standard tuning on bass?
Standard 4-string bass tuning is E A D G, from lowest string to highest string.
What is drop D tuning on bass?
Drop D bass tuning lowers only the lowest string a whole step, from E to D, giving D A D G.
What is drop C tuning on bass?
Drop C bass tuning lowers every string a whole step from standard and then drops the lowest string an additional step, giving C G C F.
What tuning does a 5-string bass use?
5-string basses commonly use B E A D G, which adds a low B string below standard 4-string tuning.
Do I need heavier strings for drop tunings on bass?
Tuning down reduces string tension. A heavier gauge helps restore some of that tension, which is why heavier strings are often used for drop tunings. This affects feel and tension specifically, not tone or sustain on its own.
What gauge bass strings are best for standard tuning?
There's no single required gauge. A common, versatile starting point for a 4-string bass in standard tuning is around .045–.105. Our What Gauge Bass Strings Should I Use? guide covers how to choose based on your instrument and feel.
Should beginners use standard bass tuning?
Yes. Standard tuning is the default for most bass instruction, songs, and reference material, which makes it the most practical starting point for new players.
Do 5-string and 6-string basses need different strings than 4-string basses?
5-string and 6-string basses require sets that include the appropriate additional string, typically a low B on a 5-string and both a low B and high C on a standard 6-string. Gauge, scale length, construction, and proper string fitment still need to match the instrument. We'll cover 5-string and 6-string gauge selection in more detail in a dedicated guide.
Do I need a setup after changing bass tunings?
It depends on the change. Moving to Drop D alone may not require a setup if the bass continues to play properly. A significant or permanent change in tuning or string gauge can affect neck relief, action, nut fit, and intonation, and having those checked by a qualified technician is the most reliable way to know for sure.
Can I tune a 4-string bass to B?
Yes, a 4-string can be set up for a lower tuning such as B F# B E or B E A D, depending on what range you're going for. As the tuning gets lower, appropriate string gauge, fitment, and setup all become more important to keep the bass playing and sounding the way you expect.
