About A 7 Guitar Chord

A 7 Guitar chord contains A, C♯, E, G. Its sound is tense and strongly directional.

Character and sound

Tense and strongly directional.

Musical context and history

The dominant seventh is central to functional harmony: a major triad plus minor seventh creates a strong tendency to resolve. It is also fundamental to blues and jazz.

How and where it is used

Use it as a dominant that pushes toward another chord, or as a stable groove color in blues, funk and rock.

On guitar, the same pitch collection can appear in several fretboard positions. Favor comfortable fingerings, guide tones and open strings when useful; the map shows all available positions across the first twelve frets. Everything you see and hear on this page comes from the same note set shown above.

Harmonic and musical relationships

As a dominant sonority on A, a common functional resolution moves toward D. Alterations and extensions change the color while preserving that tension-and-resolution reference.

The formula on this page is 1 · 3 · 5 · ♭7 and, from A, produces the notes A · C♯ · E · G.
