A — Major

A · C♯ · E

The A chord is built from the root, a major third, and a perfect fifth — A, C♯, E. Bright and stable — the first chord most pianists learn and the anchor of countless songs.

Am — Minor

A · C · E

The Am chord is built from the root, a minor third, and a perfect fifth — A, C, E. Darker and more wistful than major, and just as common across every style.

Aaug — Augmented

A · C♯ · E♯

The Aaug chord is built from the root, a major third, and a raised fifth — A, C♯, E♯. Restless and dreamlike; often a stepping-stone between two ordinary chords.

Asus4 — Suspended fourth

A · D · E

The Asus4 chord is built from the root, a perfect fourth, and a perfect fifth (the fourth replaces the third) — A, D, E. Open and suspended — it leans forward and loves to resolve to the plain major chord.

Amaj7 — Major seventh

A · C♯ · E · G♯

The Amaj7 chord is built from a major triad plus a major seventh — A, C♯, E, G♯. Lush, warm and jazzy — the classic "dreamy" piano sound.

A7 — Dominant seventh

A · C♯ · E · G

The A7 chord is built from a major triad plus a minor seventh — A, C♯, E, G. Bluesy and unresolved; the workhorse of blues, gospel and jazz turnarounds.

Am7 — Minor seventh

A · C · E · G

The Am7 chord is built from a minor triad plus a minor seventh — A, C, E, G. Mellow and smooth — the backbone of soul, R&B and jazz comping.

Am7b5 — Half-diminished (m7♭5)

A · C · E♭ · G

The Am7b5 chord is built from a diminished triad plus a minor seventh — A, C, E♭, G. Also called half-diminished; most often the "ii" chord that opens a minor ii–V–i.

Adim7 — Diminished seventh

A · C · E♭ · G♭

The Adim7 chord is built from four notes stacked in minor thirds — A, C, E♭, G♭. Maximally tense and perfectly symmetrical — a favourite for passing and leading between chords.

Am6 — Minor sixth

A · C · E · F♯

The Am6 chord is built from a minor triad plus a major sixth — A, C, E, F♯. Moody and sophisticated — a staple of jazz standards.
