Diatonic Chords Built in 4ths

Diatonic Chords Built in 4ths


Diatonic chords are built in thirds whether they are triads or 4 part chords. If you refer to my video and chart on diatonic triads you can see it spelled out for you. The concept of building and utilizing chords in fourths is used more in jazz and progressive rock and will usually be 4 part chords not triads. Below I have a diagram of a C major scale and how to build a diatonic chord in 4ths.

C  D  E  F  G  A  B  C  D  E                      C major 7th chord  
   D  E  F  G  A  B  C  D  E  F                   D minor 7th chord
      E  F  G  A  B  C  D  E  F  G                E minor 7th chord 
         F  G  A  B  C  D  E  F  G  A             F major 7th chord      
            G  A  B  C  D  E  F  G  A  B          G dominant 7th chord  
               A  B  C  D  E  F  G  A  B  C       A minor 7th chord     
                  B  C  D  E  F  G  A  B  C  D    B minor 7th b5 chord 


Although the 11th degree of the chord is present, jazz musicians still use this form as using diatonic chords in the traditional manner. Many jazz players will leave the root out of the diatonic chords to give it an ambiguous tonal center. Still this is a concept worth investigating to give your chord playing a fresh and innovative sound. In these videos I will use the Key of G major, C major and F major as examples.
