A chord is multiple notes played simultaneously. Chords are defined by semitone intervals from a root note.
Common Triads
| Type | Intervals | Character |
|---|---|---|
| Major | [0, 4, 7] | bright, happy |
| Minor | [0, 3, 7] | dark, melancholic |
Seventh Chords
| Type | Intervals | Character |
|---|---|---|
| Dominant 7th | [0, 4, 7, 10] | tense, jazzy |
| Major 7th | [0, 4, 7, 11] | smooth, dreamy |
Example: C Major (root = MIDI 60)
root + 0 = 60 → C4
root + 4 = 64 → E4
root + 7 = 67 → G4Your Task
