Identifying chords from note combinations
A chord is three or more notes played together. Major chords use root, major third, perfect fifth intervals. Minor chords use root, minor third, perfect fifth. Seventh chords add minor seventh interval. The calculator identifies which chord name matches the notes you input, handling common voicings (root position, inversions, extended notes) and rare combinations.
How inversions and voicings affect chord naming
C major in root position is C-E-G. In first inversion (E bass) it is C/E. In second inversion (G bass) it is C/G. Voicings add extra octaves or extensions (7th, 9th). The calculator shows chord name and which inversion or voicing you have played.
Why some note combinations don't form recognizable chords
Arbitrary note combinations might not form standard chords. If you play three notes that don't fit major, minor, dominant seventh, or other chord patterns, the calculator might show nothing. This is not a bug - it means you have played random notes rather than a chord.
FAQ
What is an inversion?
An inversion is a chord with a different note in the bass. C major (C-E-G) is root position. E in bass (E-G-C) is first inversion. G in bass (G-C-E) is second inversion.
Can the tool identify jazz chords?
Yes, it recognizes triads, seventh chords, ninths, and extended voicings common in jazz. Complex chords with many notes may not match any standard chord name.
What if the chord doesn't display a name?
It means the note combination doesn't match a standard chord pattern. Try removing or changing a note to form a recognizable chord.
