A chord is three or more notes played together. Triads built from a root, a third, and a fifth are the most common. Adding a seventh creates the richer tones used in jazz, blues, and R&B.

What is the difference between major and minor chords?

Major chords have a major third (4 semitones above the root) and sound bright. Minor chords have a minor third (3 semitones) and sound darker or more melancholic.

How do I find a chord by its notes?

The Chord Finder lets you look up chords by name and see the constituent notes, intervals, piano voicing, and guitar fingering so you can move from a name to something playable.

Reading the intervals

R — root, the chord's name.
3 vs ♭3 — major vs minor third. Defines the mood.
♭7 — dominant 7th (bluesy). 7 = major 7th (jazzy).

Open vs barre

Open chords use unfretted strings (the heavy fret line at the top is the nut). Barre chords clamp one finger across strings at a higher position — the "fr" label shows which fret to start at.
