Music Theory QuickThink: 

-          If the root note of a chord is a 3rd above, or below, the root of the chord that precedes it, to the two chords have an ascending, or descending, 3rdroot motion relationship respectively.

-          Chords possessing the descending third relationship include (I – vi) (vi – IV) (IV – ii) (ii – vii) (vii – V) (V – iii) (iii – I)

-          Chords possessing the ascending third relationship include (I – iii) (iii – V) (V – vii) (vii – ii) (ii – IV) (IV – vi) (vi – I)

-          IMPORTANT: In written notation, the bass of the second chord does not actually have to ascend or descend by a 3rd in order for the two chords to have this relationship (example:  I – vi6  is a descending 3rd by root motion relationship, even though the written bass motion is likely a unison or octave)
