The Eadd9 mandolin chord is a add 9th chord with the notes E, G#, B, F#. Its first mandolin voicing is the open position: G string at fret 1 (index finger); D string at fret 4 (ring finger); A string at fret 2 (middle finger); E string open. Whether you are learning it for the first time or checking a voicing, this page has the notes, the mandolin fingerings, the inversions and alternatives, and the progressions it appears in.
What notes are in the Eadd9 chord?
The Eadd9 chord is a add 9th chord, and its notes are fixed: E, G#, B, 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 Eadd9 at a glance. On the mandolin, the open position of Eadd9 puts those notes under your fingers in the order the fingering lists them.
| Note | Interval |
|---|---|
| E | Root |
| G# | 3 |
| B | 5 |
| 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 Eadd9 are 3, 5, 9. Learn those intervals rather than memorising the shape alone, because the same interval pattern transposed to another root gives you the same quality of chord anywhere. On the mandolin, the notes appear in the order the fingering dictates, but the set of notes never changes.
Eadd9 sounds fresh and spacious, a major chord with one extra colour note that never sounds crowded. That character comes straight from the intervals above, not from the instrument: the same notes on piano, guitar or ukulele carry the same colour, even though the voicing changes. On the mandolin, the open position of Eadd9 puts those notes under your fingers in the order the fingering lists them.
Comparing Eadd9 with its closest relatives helps to fix it in your ear. In short, add9 against 9th: Eadd9 has no 7th at all, while the dominant 9th adds the flattened 7th D. The add9 is settled; the 9th is restless. 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 mandolin, the open position of Eadd9 puts those notes under your fingers in the order the fingering lists them.
How to play Eadd9 on mandolin
On the mandolin, Eadd9 has 3 voicings in the data below, and each one uses the same notes — E, G#, B, F# — in a different place on the neck. Start with the first voicing and get it clean before you try the movable shapes further up the neck. Finger numbers below use 1 for the index finger, 2 for the middle finger, 3 for the ring finger and 4 for the little finger, and x means the string is not played.
Another way to play Eadd9 is the open position, in open position: G string at fret 1 (index finger); D string at fret 4 (ring finger); A string at fret 2 (middle finger); E string open. The stretch is the challenge: the fretted notes span from fret 1 to fret 4, so keep your thumb low behind the neck and let your fingers reach rather than squeezing the neck. Strum or pluck it slowly first and check that every note in Eadd9 — E, G#, B, F# — sounds, with no buzz and no accidental open string.
For the barre chord, Eadd9 sits in around fret 4: G string at fret 4 (index finger); D string at fret 4 (index finger); A string at fret 7 (middle finger); E string at fret 4 (index finger). It barres across strings 1 to 4 at fret 4 with the index finger. The barre is the hard part: the index finger must press every string from 1 to 4 evenly at fret 4, so roll it slightly onto its bony side and keep it close to the fret wire. If the barre buzzes, move it a fraction closer to the fret and press from the arm, not the thumb alone. Strum or pluck it slowly first and check that every note in Eadd9 — E, G#, B, F# — sounds, with no buzz and no accidental open string.
The movable voicing puts Eadd9 in around fret 6: G string at fret 9 (ring finger); D string at fret 6 (index finger); A string at fret 9 (little finger); E string at fret 7 (middle finger). The stretch is the challenge: the fretted notes span from fret 6 to fret 9, so keep your thumb low behind the neck and let your fingers reach rather than squeezing the neck. Strum or pluck it slowly first and check that every note in Eadd9 — E, G#, B, F# — sounds, with no buzz and no accidental open string.
Choosing between the voicings of Eadd9 is a musical decision, not a right-or-wrong one. The open or low-position voicing rings the most and suits strumming, while a barre or movable voicing lets you slide Eadd9 up the neck to any key without changing the shape. When you change chords, pick the voicing of Eadd9 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into Eadd9 from the chord that comes before it in your song, not the chord on its own, because the move is the skill. On the mandolin, start with the first voicing above and listen for the notes E, G#, B, F# in Eadd9.
A short practice routine for Eadd9 on the mandolin: play the first voicing four times slowly, checking each note, then change to it from the chord a fourth above E and back, four times, at a slow tempo. Then play the second voicing the same way. If a note buzzes, stop and fix the finger placement rather than playing through the buzz — clean notes at a slow tempo become clean notes at full tempo, while buzzes practised fast become habits.

Common mistakes
These are the mistakes that most often make Eadd9 sound wrong on the mandolin, and each one has a concrete fix. Work through them one at a time rather than trying to fix everything at once.
Adding a 7th by mistake. If D or D# creeps in, the chord becomes a 9th or major 9th with a different function. The add9 has four notes only: E, G#, B, F#. On the mandolin, start with the first voicing above and listen for the notes E, G#, B, F# in Eadd9.
Muting the 9th. F# is the whole point of this chord. If the string or key carrying it is muted, the chord is just a major triad. On the mandolin, the open position of Eadd9 puts those notes under your fingers in the order the fingering lists them.
Playing the 9th too low. F# close to the root can sound muddy. Keep it in a higher octave than the root and 3rd. On the mandolin, start with the first voicing above and listen for the notes E, G#, B, F# in Eadd9.
Overusing it. Because it is so pretty, it is tempting to use it everywhere. Save it for moments that deserve the lift. On the mandolin, start with the first voicing above and listen for the notes E, G#, B, F# in Eadd9.
Where Eadd9 is used
Eadd9 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 E major, the key of A major, the key of B major. a tonic colour in pop, folk and rock, brighter than a plain major triad. 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 Eadd9 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the mandolin, the open position voicing is the place to hear it in Eadd9.
Because Eadd9 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 Eadd9 in a progression in any key and hear how it connects to the chords around it. On the mandolin, the open position of Eadd9 puts those notes under your fingers in the order the fingering lists them.
The same chord on other instruments is covered in Eadd9 on guitar, Eadd9 on piano, Eadd9 on ukulele, and the scales that fit over it are the E major scale and the E minor pentatonic scale. Learning Eadd9 on the mandolin and then checking it on another instrument is one of the best ways to fix the notes — E, G#, B, F# — in your memory, because the notes stay the same while everything else changes.
Practising Eadd9
A short worked example makes Eadd9 concrete. Play the four-chord progression A – E – F#m – D in A major, the key Eadd9 most often resolves toward: A – E – F#m – D. Play each chord for one bar at a slow tempo, and listen to how Eadd9 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 Eadd9 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the mandolin, the open position voicing is the place to hear it in Eadd9.
For a second exercise, play Eadd9 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 Eadd9 is built for when it acts as a dominant. Finish by playing Eadd9 on its own, slowly, and naming each note out loud as you play it: E, G#, B, 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 mandolin, the open position of Eadd9 puts those notes under your fingers in the order the fingering lists them.
Frequently asked questions
How do you play Eadd9 on the mandolin?
The first voicing is the open position: frets 1–4–2–0, fingers 1–3–2–0, on the mandolin. That voicing uses the notes E, G#, B, F#, and it is the one to learn first. The page above lists more voicings for Eadd9, so you can choose the shape nearest the chords around it.
Is Eadd9 hard to play on the mandolin?
It depends on the voicing. The first voicing of Eadd9 on the mandolin is the easiest starting point, and the movable voicings further up the neck are harder because they need a barre or a wider stretch. Practise the first voicing cleanly at a slow tempo before you try the others, and the harder shapes will come more easily.
What is the easiest voicing of Eadd9 on the mandolin?
The open position is the easiest voicing listed for Eadd9 on the mandolin: frets 1–4–2–0, fingers 1–3–2–0. Learn that shape first, get every note ringing cleanly, and only then move on to the alternative voicings further up the neck.
What does add9 mean in Eadd9?
Add9 means the 9th, F#, is added to the major triad without any 7th. Eadd9 contains E, G#, B, F# — root, major 3rd, perfect 5th and the added 9th. On the mandolin, the first voicing above shows where that note sits.
What is the difference between Eadd9 and E9?
E9 adds the flattened 7th D as well as the 9th, which makes it a dominant chord that wants to resolve. Eadd9 has no 7th, so it sounds settled and works as a tonic. On the mandolin, the first voicing above shows where that note sits.
