What Are Chord Tones?
Chord tones are the individual notes that make up a chord. Understanding which notes belong to which chord is fundamental for playing, writing, and improvising in any style.
How Chords Are Built
Chords are constructed by stacking intervals — most commonly thirds — starting from a root note.
A triad uses three notes: root, third, and fifth. A seventh chord adds one more third on top: root, third, fifth, and seventh.
Major Triad
Built from a root, major third (+4 semitones), and perfect fifth (+7 semitones).
C major: C – E – G
Minor Triad
Built from a root, minor third (+3 semitones), and perfect fifth (+7 semitones).
C minor: C – Eb – G
Dominant 7th Chord
A major triad plus a minor seventh (10 semitones above the root).
C7: C – E – G – Bb
Major 7th Chord
A major triad plus a major seventh (11 semitones above the root).
Cmaj7: C – E – G – B
Minor 7th Chord
A minor triad plus a minor seventh.

- Improvising — targeting chord tones over changes makes solos sound intentional
- Ear training — hearing individual chord tones builds harmonic awareness
