Seventh Chord Inversion (Music Theory Lesson)

Like triads, seventh chords can be inverted by moving the lowest note up an octave. Root position is the same as a triad -- the root is the lowest (bass) note.

Let's invert the chord. First inversion is also the same -- the third is the lowest note.




Let's invert the chord again. Second inversion is also the same -- the fifth is the lowest note.




Let's invert the chord again. Now, the seventh is the lowest note of the chord. This is called third inversion.




Let's invert the chord one more time. Notice that the chord returns to root position. As you have already learned, a root position seventh chord is identified by a roman numeral with a 7.




A first inversion seventh chord is identified by a roman numeral with a 6 and a 5.




A second inversion seventh chord is identified by a roman numeral with a 4 and a 3.




Finally, a roman numeral with a 2 identifies a third inversion seventh chord.
