A Minor Seventh Piano Chord (Am7)

Am7 is built from A, C, E and G — the formula 1 · ♭3 · 5 · ♭7, or 3, 7 and 10 semitones above A. The shape uses white keys only, and you can hear it, invert it and compare it below.

Chord tones

The notes in Am7

A minor seventh chord adds a minor seventh above a minor triad. It keeps the darker colour of the minor third, but the extra note softens the edge, so the chord feels relaxed rather than sad. Minor sevenths are the natural seventh chords on the second, third and sixth degrees of a major scale.

Each tone of A minor seventh with its interval, scale degree, distance in semitones from A and a suggested right-hand finger.

Step by step

How to play Am7 on piano

Find A: it is the white key between the second and third black keys of a group of three.
Build upwards from A using 3, 7 and 10 semitones to reach C, E and G.
With the right hand, place finger 1 on A, finger 2 on C, finger 3 on E and finger 5 on G. Keep the wrist level and the knuckles rounded.
Every note here is a white key, so you can sit your hand slightly further out from the fallboard.
Play the notes together, then one at a time from the bottom up, and listen to how Am7 settles.
Try first inversion as well: C – E – G – A. Inversions let you change chords without jumping around the keyboard.

Inversions

Am7 in 4 positions

An inversion keeps the same 4 notes and simply moves the lowest one up an octave. Learning them means you can change chords with small hand movements instead of jumping to a new part of the keyboard.

Root position

A – C – E – G

The root A is the lowest note. This is the shape most people learn first.

First inversion

C – E – G – A

C is the lowest note, so the minor third sits in the bass and the notes below it move up an octave.

Second inversion

E – G – A – C

E is the lowest note, so the perfect fifth sits in the bass and the notes below it move up an octave.

Third inversion

G – A – C – E

G is the lowest note, so the minor seventh sits in the bass and the notes below it move up an octave.

In context

Which keys contain Am7

In C major the chord functions as vi7. Altogether it is produced by the scales of 6 keys, so learning it once pays off in several places.

C majorvi7
F majoriii7
G majorii7
D minorv7
E minoriv7
A minori7

Chord tones are spelled by the degree they occupy, so the third of a minor chord is written as a flat rather than a sharp even though it is the same key on the piano. A double sharp such as F## means the key one whole tone above F.

Compare

Am7 against A7

Am7 and A7 share A, E and G. Moving the major third C# down 1 semitone to the minor third C turns A7 into Am7.

Practise the pair together: hold the shared notes A, E, G still and move only the one finger. Hearing that single change is the quickest way to recognise the two chords by ear.
