Guitar Chords Explorer

Use the interactive scale explorer below to discover chords. Select a scale and see all the chords that can be built from it, complete with finger positions and musical theory.

How it works:

• Choose a scale root note and type (Major, Minor, etc.)
• The fretboard will show all notes in that scale
• Below you'll see all diatonic chords from that scale
• Each chord shows its Roman numeral function (I, ii, iii, IV, V, vi, vii°)
• Click any fret to hear the note, or chord buttons to hear the full chord

Chord Theory Fundamentals

Every scale contains 7 chords, each with a specific musical function:

I - Tonic (Major)

The home chord. Creates stability and resolution. The "I" chord feels like home base.

ii - Supertonic (Minor)

Creates mild tension. Wants to resolve to the V or I chord. Common in progressions.

iii - Mediant (Minor)

Has a bittersweet quality. Shares 2 notes with the tonic. Less commonly used.

IV - Subdominant (Major)

Creates openness and anticipation. Great for building tension toward the dominant.

V - Dominant (Major)

Maximum tension! This chord desperately wants to resolve back to I (the tonic).

vi - Submediant (Minor)

Shares notes with the tonic. Creates a sense of rest, supports the I chord.

vii° - Leading Tone (Diminished)

Maximum dissonance and tension. Resolves strongly back to the tonic. Very powerful!
