When you are harmonizing melodies and writing music, there are three situations where it is appropriate to use a 6/4 chord.
- Pedal 6/4
- Passing 6/4
- Cadential 6/4
The pedal 6/4 typically occurs in the patterns I–IV 6/4–I or V–I 6/4 – V.
The passing 6/4 typically occurs in the patterns I-V 6/4-I6 (or its retrograde) and IV-I 6/4-IV6 (or its retrograde).
