Music Theory QuickThink: 

-          A Descending Third Harmonic sequence is a series of chords, where the root note of those chords are each a descending 3rd apart.

-          An example using roman numerals is I, vi, IV, ii, vii, V, iii, I  This is a Literal Descending 3rd Harmonic Sequence (READ NEXT BULLETPOINT !)

-          IMPORTANT: Because of the issue of parallel 5ths and 8ves that occur when going directly from one chord to the next of those listed above, what is known as the Traditional Descending 3rd Harmonic Sequence has chords in-between the chords of the pattern listed above.

-          The most common Traditional Descending 3rd harmonic sequence is the following, I – V – vi – iii – IV….

-          Unlike the descending 5th sequence, the entire Roman numeral pattern does not usually appear in real music (does not create a circle progression)
