Inversions

When the base not of a chord isn't its root note it is an inversion. Depending on which note is the base, the inversion is named differently. Inversions sound very different to chords built on the root note and have an unstable feeling.

Inversions increase the space between the notes, making the chord sound more open.

Triads

• First Inversion has a third in the bass, then fifth, then root, meaning intervals are Minor Third, Minor Sixth
• Second Inversion has a fifth in the bass. Root, then root, then third, meaning intervals are Perfect Fourth, Major Sixth
