2.  Bass Arpeggiation- The bass moves down so that the notes outline a chord. A I6/4 chord will be needed to achieve the arpeggiated bass.  Melodic Bass- If the bass line takes on a more melodic role with the upper voices providing the harmony, then a I 6/4 chord may be used.

3.  Used at the end of the of a piece to extend the Final Cadence Sound  Extends the Dominant or V chord sound in the bass  The I 6/4 occurs on the strong beat in a measure: i.e. 1 or 3 in 4/4/; 1 in ¾  Typical Cadential Progression: I6/4-V-I  Voice Leading: The upper voice move into and out of the I 6/4 chord smoothly

4.  The passing Six-Four is used to harmonize the middle note of a three-note scalar figure in the bass.  Although any triad may be used as a passing six-four chord, the following are the most commonly used and are found in both major and minor. › I- V6/4-I6 › IV6-I6/4-ii6  Voice Leading: The upper voice should move in contrary motion to the bass line

5.  Used as an Elaboration of a static root position triad  The Bass and doubled note are held while the other two voices move up and down by step  Common Pedal Progression Chords: › I-(IV6/4)-I › V-(I6/4)-V  6/4 chord must occur on a weak beat and must be analyzed in parentheses.

6.  The Bass (5 th of the Chord) should be doubled.  The other voices move as smoothly as possible-often by step-both into and out of the six four chord.
