What chords and notes go together?
A chord is a group of notes played together, typically built from a root note, a third, and a fifth. The simplest way to match a note to a chord is by playing one of the chord tones — the notes that make up the chord.
Common Chords and Their Notes
- C Major → C – E – G
- A Minor → A – C – E
- G7 (Dominant 7th) → G – B – D – F
- D Minor → D – F – A
- B Diminished → B – D – F
- C Augmented → C – E – G#
If you are playing a melody over a chord, using these chord tones will ensure your melody sounds harmonious and blends well.
Matching Chords with Scales
To expand beyond just chord tones, use the scale that corresponds to each chord. This is useful when soloing, improvising, or composing.
| Chord | Best Matching Scale |
|---|---|
| C Major (C–E–G) | C Major (C D E F G A B) |
| A Minor (A–C–E) | A Natural Minor (A B C D E F G) |
| G7 (G–B–D–F) | G Mixolydian (G A B C D E F) |
| D Minor (D–F–A) | D Dorian (D E F G A B C) |
| B Diminished (B–D–F) | B Locrian (B C D E F G A) |
| C Augmented (C–E–G#) | C Whole-Tone (C D E F# G# A#) |
Using Tension and Resolution in Music
To make music sound dynamic and interesting, create tension and then resolve it.
Adding tension:
- Play non-chord tones (notes not in the chord) to add dissonance
- Use suspended chords (e.g., Csus4: C–F–G) before resolving to a regular chord
- Add dominant 7th chords (e.g., G7: G–B–D–F) before resolving to the tonic (C major)
Resolving tension:
- Move dissonant notes back to chord tones
- Follow a dominant-to-tonic progression (e.g., G7 → C major)
- Use a diminished chord (e.g., B°: B–D–F) before resolving up a half step to a stable chord
Expanding Chords with Extensions and Colors
Beyond basic triads, extensions and colorful tones enhance your harmony.
| Chord Type | Example | Additional notes for color |
|---|---|---|
| Major 7th | Cmaj7 (C–E–G–B) | Add D or A for a richer sound |
| Minor 7th | Am7 (A–C–E–G) | Add B or F for jazzier progressions |
| Dominant 9th | G9 (G–B–D–F–A) | Great for blues and jazz |
Practical Tips
- Use chord tones (root, third, fifth) for safe harmony
- Use scale tones from the key for melody and improvisation
- Use passing notes for smooth transitions between chord tones
- Use tension notes carefully to create movement and drama
- Try extensions to add depth and sophistication to your chords
Matching chords with the right notes and scales is an essential skill for any musician. Whether you are playing chords, improvising a melody, or composing a song, understanding harmony will help you create music that sounds great and feels natural.
