Frequently Asked Questions
Click any notes on the fretboard to select them. The chord finder identifies the chord in real time and shows the name, symbol, and interval formula. Select notes from any strings or frets — duplicates of the same pitch are automatically handled.
The formula shows the interval of each note relative to the chord root using shorthand: R (root), b3 (minor 3rd), 3 (major 3rd), b5 (tritone), 5 (perfect 5th), #5 (augmented 5th), b7 (minor 7th), 7 (major 7th), and so on. For example, a C major chord has the formula R – 3 – 5 (root C, major 3rd E, perfect 5th G).
A set of notes can sometimes be interpreted as more than one chord depending on which note is considered the root. For example, C E G A could be C6 or Am7. The chord finder lists all valid interpretations, with the most common reading first.
Yes. Guitarists often drop the 5th (and, on 11th and 13th chords, the 9th) to make a voicing easier to play. When your selected notes don't form a complete chord but match a common shortened voicing, the chord finder still names it and marks the missing tone — for example C E B♭ is identified as "C7 (no 5th)." Complete chords are always identified first.
The tool identifies over 35 chord types including major, minor, diminished, augmented, suspended (sus2, sus4), power chords, all dominant and major/minor 7th chords, 9th, 11th, and 13th chords, add9, add4, 6th chords, and altered dominants like 7b5, 7#5, 7b9, and 7#9.
