Section 26.11 Types of Six-Four Chords
When you are harmonizing melodies and writing music, there are three situations where it is appropriate to use a \(\left.\text{}^{6}_{4}\right.\) chord.
- Pedal \(\left.\text{}^{6}_{4}\right.\)
- Passing \(\left.\text{}^{6}_{4}\right.\)
- Cadential \(\left.\text{}^{6}_{4}\right.\)
The pedal \(\left.\text{}^{6}_{4}\right.\) typically occurs in the patterns I–IV\(\left.\text{}^{6}_{4}\right.\)–I or V–I\(\left.\text{}^{6}_{4}\right.\)–V.
The passing \(\left.\text{}^{6}_{4}\right.\) typically occurs in the patterns I–V\(\left.\text{}^{6}_{4}\right.\)–I\(\left.\text{}^{6}\right.\) (or its retrograde) and IV–I\(\left.\text{}^{6}_{4}\right.\)–IV\(\left.\text{}^{6}\right.\) (or its retrograde).
In an earlier section we discussed the Cadential \(\left.\text{}^{6}_{4}\right.\) chord. Please refer to that section to review the cadential \(\left.\text{}^{6}_{4}\right.\) chord.
