First inversion

Jovan Stosic August 9, 2019

he first inversion of a chord is the voicing of a triad, seventh chord, or ninth chord in which the third of the chord is the bass note and the root a sixth above it.[1] In the first inversion of a C-major triad, the bass is E — the third of the triad — with the fifth and the root stacked above it (the root now shifted an octave higher), forming the intervals of a third and a sixth above the inverted bass of E, respectively.

In the first inversion of G-dominant seventh chord, the bass note is B, the third of the seventh chord.
