9th Chord Theory

This lesson teaches how to use 9th chords in a variety of keys to transition from a functional V dominant chord to a I chord. 

It's important to remember that the 3rd and 7th of the chord are the most important notes because they determine the tonality of the chord:

  • Major 3rd, major 7th - Major 7th chord
  • Major 3, minor 7 - Dominant 7th chord*
  • Minor 3rd, major 7th - Minor major 7th chord
  • Minor 3rd, minor 7th - Minor 7th chord

The dominant 7th chord is what we'll be building on in the lesson. Enjoy!
