- If the root note of a chord is a 5th below the root of the chord that
precedes it, to the two chords have a descending 5th root motion relationship
- Chords possessing this relationship include (I – IV) (IV – vii) (vii –
iii) (iii – vi) (vi – ii) (ii – V) (V – I)
- IMPORTANT: In written notation, the bass of the second chord does not
actually have to descend by a 5th in order for the two chords to have this relationship
(example: I – IV6 is a descending 5th by root motion relationship, even though
the written bass motion is likely a descending 3rd or and ascending 6th)
