Master harmony through systematic understanding of chord construction, function, and application
Chords are the harmonic foundation of music, created by combining three or more notes played simultaneously. They provide the emotional context, establish key centers, and create the harmonic progressions that drive songs forward. Master chord theory to unlock the secrets of harmony and composition.
A chord is a combination of three or more different notes played together. Chords are built by stacking intervals, most commonly thirds, creating harmonic structures that support melodies and establish musical context. Understanding chords involves:
Provides stability and resolution
Creates departure from tonic
Creates tension that wants to resolve
Root + Major 3rd + Perfect 5th
Example: C Major = C + E + G
Root + Minor 3rd + Perfect 5th
Example: A Minor = A + C + E
Root + Minor 3rd + Diminished 5th
Example: B Diminished = B + D + F
Major Triad + Minor 7th
Creates strong pull to tonic
Minor Triad + Minor 7th
Smooth, jazzy sound
Major Triad + Major 7th
Dreamy, ethereal quality
Bright, stable, happy sound. Foundation of Western harmony.
Darker, more emotional than major. Essential for expression.
Adds tension and color. Essential for blues, jazz, and rock.
Smooth, jazzy sound. Perfect for sophisticated harmony.
Dreamy, ethereal quality. Common in jazz and neo-soul.
Neither major nor minor. Creates suspense and resolution.
Tense and unstable. Used for dramatic effect and transitions.
Mysterious, whole-tone sound. Creates harmonic ambiguity.
Add 9ths, 11ths, and 13ths for rich, complex harmony.
The backbone of rock, punk, and metal. No 3rd means neither major nor minor.
Add color tones to triads without the 7th. Shimmery, open sound.
Warm, resolved jazz and swing sound. Major triad plus the 6th.
Bittersweet sophistication. Essential in jazz minor and bossa nova.
The ii chord in minor keys. Essential for jazz minor progressions.
Inversions and bass note chords for smooth voice leading.
The funk chord. Rich dominant sound with the added 9th for groove.
Maximum tension chords with altered 5ths and 9ths. The Hendrix chord lives here.
Chord progressions are the backbone of songs. These fundamental patterns appear across all genres and provide the harmonic framework for countless compositions.
