The Em9 bass chord is built from the notes E, G, B, D, F#. On bass it is outlined with the arpeggio E, B, E, G — root, 5th, root, 3rd. It is a minor 9th chord, and this page gives you its exact notes, the fingerings that work on the bass, the mistakes to avoid and the progressions it appears in.
What notes are in the Em9 chord?
The Em9 chord is a minor 9th chord, and its notes are fixed: E, G, B, D, F#. Every voicing on every instrument uses these same notes, in some order and in some octave — change one of them and you are playing a different chord. The table below lists each note with its interval from the root E, so you can see the structure of Em9 at a glance. On the bass, Em9 is the arpeggio E, B, E, G — root, 5th, root, 3rd — and that order is the shape to learn.
| Note | Interval |
|---|---|
| E | Root |
| G | b3 |
| B | 5 |
| D | b7 |
| F# | 9 |
The root is E, the note the chord is named after and the note your ear hears as home. Above it, the intervals in Em9 are b3, 5, b7, 9. Those intervals are the fingerprint of the minor 9th quality — any chord with the same interval pattern, on any root, is the same kind of chord. On the bass, the notes appear in the order the fingering dictates, but the set of notes never changes.
Em9 sounds warm and jazzy, the sound of slow soul, R&B and minor-key jazz. The colour is strongest when all the notes ring clearly. A muted chord tone, especially the 3rd or the 7th where the chord has one, flattens the character of Em9 noticeably. On the bass, play E, B, E, G and hear how the arpeggio spells out Em9 without ever playing it as a block.
Comparing Em9 with its closest relatives helps to fix it in your ear. In short, minor 9th against minor 7th: Em9 adds the 9th F# to the minor 7th chord. The extra note widens the sound without changing the function. Practise the two chords back to back and listen to the one note that changes — that single note is the difference between the two chords. On the bass, play E, B, E, G and hear how the arpeggio spells out Em9 without ever playing it as a block.
How to play Em9 on bass
On the bass, Em9 is not played as a full chord shape the way it is on guitar or piano. Instead you outline it with an arpeggio: the notes E, B, E, G, which are the chord tones of Em9 in the order root, 5th, root, 3rd. That pattern is the working shape for this chord on bass, and it tells the listener exactly which chord is sounding, even though you never play all the notes at once.
Practise the arpeggio of Em9 by playing E on beat one, B on beat two, E on beat three and G on beat four, one note per beat, letting each note ring for its full value. Then play it backwards — G, E, B, E — so your fingers learn the shape in both directions. The root E is the anchor: it is the note the rest of the band listens for, so land on it cleanly and on time, and let the 5th B and the 3rd G colour the bar without pulling attention away from the root.
Once the straight arpeggio of Em9 is comfortable, try playing just the root E and the 5th B for a whole bar, then add the 3rd G on the last beat as a passing colour. That root-and-5th skeleton is how most bass lines outline Em9 in a real song, and the full arpeggio is the version you use when the arrangement has space for it. Check the notes with the Bass Chord Finder and the Chord Finder, and practise the arpeggio against a slow metronome so the notes land exactly on the beat.
Common mistakes
These are the mistakes that most often make Em9 sound wrong on the bass, and each one has a concrete fix. Work through them one at a time rather than trying to fix everything at once.
Playing the major 3rd. The 3rd must stay minor (G). A major 3rd turns this into a dominant 9th, a different chord entirely. On the bass, play E, B, E, G and hear how the arpeggio spells out Em9 without ever playing it as a block.
Raising the 7th. The 7th here is D, flattened. Play D# and you get a minor-major 9th, a much tenser sound. On the bass, play E, B, E, G and hear how the arpeggio spells out Em9 without ever playing it as a block.
Crowding the voicing. Five notes need room. Drop the 5th (B) first and keep the root, minor 3rd, 7th and 9th. On the bass, play E, B, E, G and hear how the arpeggio spells out Em9 without ever playing it as a block.
Losing the 9th. Without F# this is just a minor 7th chord. Make sure the note carrying the 9th rings clearly. On the bass, the arpeggio E, B, E, G outlines Em9 one note at a time.
Where Em9 is used
Em9 is not a diatonic triad in any major or minor key, because it is an extended or altered chord, but its base triad belongs to the key of C major, the key of D major, the key of G major. the ii chord in major keys and the i chord in minor keys, in richer form. As a dominant-type chord it also points toward A major, the key a perfect fourth above E, which is the tonic it most often resolves to. That is where Em9 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the bass, the arpeggio E, B, E, G outlines Em9 one note at a time.
Because Em9 is an extended or altered chord, it appears in progressions as a colour or a dominant rather than as a diatonic staple. Try it in place of the plain E triad in a progression you already know, and listen to how the extra notes change the feel — that substitution is the usual way extended chords enter real music. The Chord Progression Builder lets you try Em9 in a progression in any key and hear how it connects to the chords around it. On the bass, Em9 is the arpeggio E, B, E, G — root, 5th, root, 3rd — and that order is the shape to learn.
The same chord on other instruments is covered in Em9 on guitar, Em9 on piano, Em9 on ukulele, and the scales that fit over it are the E major scale and the E minor pentatonic scale. Learning Em9 on the bass and then checking it on another instrument is one of the best ways to fix the notes — E, G, B, D, F# — in your memory, because the notes stay the same while everything else changes.
Practising Em9
A short worked example makes Em9 concrete. Play the four-chord progression A – E – F#m – D in A major, the key Em9 most often resolves toward: A – E – F#m – D. Play each chord for one bar at a slow tempo, and listen to how Em9 sounds in that sequence — whether it feels like home, like a lift, or like a chord on its way somewhere else. Then play the same four chords in a different order, starting on Em9 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the bass, play E, B, E, G and hear how the arpeggio spells out Em9 without ever playing it as a block.
For a second exercise, play Em9 and then the chord a fourth above E, back and forth, four times each. That move — a chord and the chord a fourth above it — is the most common resolution in Western music, and it is the move Em9 is built for when it acts as a dominant. Finish by playing Em9 on its own, slowly, and naming each note out loud as you play it: E, G, B, D, F#. Naming the notes while you play them is what turns a shape into knowledge you can use in any key. Test yourself with the Practice Chord Quiz and keep time with the Metronome as the tempo rises. On the bass, the arpeggio E, B, E, G outlines Em9 one note at a time.
Frequently asked questions
Should you play the full Em9 chord on bass?
Usually not. On bass the chord is outlined with the arpeggio E, B, E, G, not strummed as a block. Playing all the notes at once sounds muddy in the low register and hides the root, which is the note the rest of the band is listening for.
What notes are in Em9?
Em9 contains E, G, B, D, F#: root E, minor 3rd G, perfect 5th B, flattened 7th D and the 9th F#. It is a minor 7th chord with the 9th added. On the bass, the arpeggio above shows where that note sits.
Is Em9 major or minor?
Minor. Its 3rd is G, and the flattened 7th D keeps it mellow. The 9th F# adds width, not brightness. On the bass, the arpeggio above shows where that note sits.
Where is Em9 used?
Em9 is a ii chord in major keys and a tonic in minor-key jazz, soul and R&B. It suits slow tempos and open voicings where its depth has room to show. On the bass, the arpeggio above shows where that note sits.
How do you play Em9 on the bass?
Outline it with the arpeggio E, B, E, G: root, 5th, root, 3rd. Play one note per beat, with the root E on beat one, and let each note ring. That arpeggio tells the listener exactly which chord is sounding, even though you never play all the notes of Em9 at once.
