On the mandolin, the Am11 chord is the minor 11th chord built from A, C, E, G, B, D. Its first mandolin voicing is the open position: G string at fret 2 (index finger); D string open; A string at fret 3 (middle finger); E string at fret 3 (middle finger). Keep this page open while you practise: it lists the notes, every practical voicing, the mistakes that make it sound wrong and the progressions where it does its best work.
What notes are in the Am11 chord?
The Am11 chord is a minor 11th chord, and its notes are fixed: A, C, E, G, B, D. 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 A, so you can see the structure of Am11 at a glance. On the mandolin, the open position of Am11 puts those notes under your fingers in the order the fingering lists them.
| Note | Interval |
|---|---|
| A | Root |
| C | b3 |
| E | 5 |
| G | b7 |
| B | 9 |
| D | 11 |
The root is A, the note the chord is named after and the note your ear hears as home. Above it, the intervals in Am11 are b3, 5, b7, 9, 11. Once you know the intervals, you can build Am11 from any root by counting the same semitone steps, which is how the chord works in every key. On the mandolin, the notes appear in the order the fingering dictates, but the set of notes never changes.
Am11 sounds smooth, deep and modern — the minor 11th is the richest minor colour in common use. 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 voicing is the place to hear it in Am11.
Comparing Am11 with its closest relatives helps to fix it in your ear. In short, minor 11th against minor 9th: Am11 adds the 11th D to the minor 9th chord. The extra note widens the sound without changing the function. Play both chords slowly, one after the other, and notice which note moves. Naming that note out loud while you play is the fastest way to learn the difference. On the mandolin, the open position voicing is the place to hear it in Am11.
How to play Am11 on mandolin
On the mandolin, Am11 has 3 voicings in the data below, and each one uses the same notes — A, C, E, G, B, D — in a different place on the neck. The first voicing below is the one to learn first, and the alternatives cover the rest of 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.
The open position is the voicing to learn if you want Am11 in around fret 1: G string at fret 2 (index finger); D string open; A string at fret 3 (middle finger); E string at fret 3 (middle finger). This voicing is comfortable because the fretted notes sit close together, from fret 2 to fret 3, so your hand stays relaxed and every note can ring. Strum or pluck it slowly first and check that every note in Am11 — A, C, E, G, B, D — sounds, with no buzz and no accidental open string.
The barre chord puts Am11 in around fret 5: G string at fret 5 (index finger); D string at fret 5 (index finger); A string at fret 5 (index finger); E string at fret 5 (index finger). It barres across strings 1 to 4 at fret 5 with the index finger. The barre is the hard part: the index finger must press every string from 1 to 4 evenly at fret 5, 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 Am11 — A, C, E, G, B, D — sounds, with no buzz and no accidental open string.
The movable voicing is the voicing to learn if you want Am11 in around fret 3: G string open; D string open; A string at fret 3 (index finger); E string at fret 5 (middle finger). This voicing is comfortable because the fretted notes sit close together, from fret 3 to fret 5, so your hand stays relaxed and every note can ring. Strum or pluck it slowly first and check that every note in Am11 — A, C, E, G, B, D — sounds, with no buzz and no accidental open string.
Choosing between the voicings of Am11 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 Am11 up the neck to any key without changing the shape. When you change chords, pick the voicing of Am11 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into Am11 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, the open position of Am11 puts those notes under your fingers in the order the fingering lists them.
A short practice routine for Am11 on the mandolin: play the first voicing four times slowly, checking each note, then change to it from the chord a fourth above A 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. Use the Mandolin Chord Finder to see the diagram for Am11 while you practise, and the Chord Finder to compare it with the same chord on other instruments.
Common mistakes
These are the mistakes that most often make Am11 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.
Missing one string of a course. Mandolin strings come in pairs, and Am11 needs both strings of each course to sound. If one string of a pair is muted by a neighbouring finger, the chord sounds thin. Check each course separately by plucking it on its own. On the mandolin, start with the first voicing above and listen for the notes A, C, E, G, B, D in Am11.
Playing the major 3rd. The 3rd must stay minor (C). A major 3rd turns this into a dominant 11th. On the mandolin, the open position voicing is the place to hear it in Am11.
Crowding the voicing. Six notes need space. Drop the 5th (E) first and spread the rest across octaves. On the mandolin, start with the first voicing above and listen for the notes A, C, E, G, B, D in Am11.
Losing the 11th. Without D this is just a minor 9th chord. The 11th is the note that makes it an 11th. On the mandolin, the open position voicing is the place to hear it in Am11.
Where Am11 is used
Am11 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 F major, the key of G major. a minor tonic in jazz and neo-soul, richer than the minor 9th. As a dominant-type chord it also points toward D major, the key a perfect fourth above A, which is the tonic it most often resolves to. That is where Am11 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 Am11.
Because Am11 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 A 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 Am11 in a progression in any key and hear how it connects to the chords around it. On the mandolin, start with the first voicing above and listen for the notes A, C, E, G, B, D in Am11.
The same chord on other instruments is covered in Am11 on guitar, Am11 on piano, Am11 on ukulele, and the scales that fit over it are the A major scale and the A minor pentatonic scale. Learning Am11 on the mandolin and then checking it on another instrument is one of the best ways to fix the notes — A, C, E, G, B, D — in your memory, because the notes stay the same while everything else changes.
Practising Am11
A short worked example makes Am11 concrete. Play the four-chord progression D – A – Bm – G in D major, the key Am11 most often resolves toward: D – A – Bm – G. Play each chord for one bar at a slow tempo, and listen to how Am11 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 Am11 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the mandolin, start with the first voicing above and listen for the notes A, C, E, G, B, D in Am11.
For a second exercise, play Am11 and then the chord a fourth above A, 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 Am11 is built for when it acts as a dominant. Finish by playing Am11 on its own, slowly, and naming each note out loud as you play it: A, C, E, G, B, D. 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 Am11 puts those notes under your fingers in the order the fingering lists them.
Frequently asked questions
Is Am11 major or minor?
Minor. Its 3rd is C, and the flattened 7th G keeps it mellow. The 9th and 11th add width, not brightness. On the mandolin, check the first voicing above for that note.
Where is Am11 used?
Am11 is a minor tonic in jazz, neo-soul and R&B, and a ii chord in major keys. It suits slow tempos and open voicings. On the mandolin, check the first voicing above for that note.
How do you play Am11 on the mandolin?
The first voicing is the open position: frets 2–0–3–3, fingers 1–0–2–2, on the mandolin. That voicing uses the notes A, C, E, G, B, D, and it is the one to learn first. The page above lists more voicings for Am11, so you can choose the shape nearest the chords around it.
Is Am11 hard to play on the mandolin?
It depends on the voicing. The first voicing of Am11 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 Am11 on the mandolin?
The open position is the easiest voicing listed for Am11 on the mandolin: frets 2–0–3–3, fingers 1–0–2–2. Learn that shape first, get every note ringing cleanly, and only then move on to the alternative voicings further up the neck.
