key term - Ii6 Chord

Definition

The ii6 chord is a minor triad built on the supertonic scale degree, with the root positioned in the bass, creating a first inversion. This chord plays an essential role in establishing harmonic movement, especially in relation to cadential 6/4 chords, as it often serves as a predominant function leading to the dominant chord.

5 Must Know Facts For Your Next Test

1. The ii6 chord consists of the root (supertonic), minor third, and perfect fifth, but in first inversion, it emphasizes the third of the chord as the bass note.
2. In a progression, ii6 can often lead to V7 (dominant seventh chord), creating a smooth transition and establishing a strong tonal center.
3. This chord typically appears in major keys and is crucial for establishing tension before resolving to the dominant chord.
4. The use of ii6 chords helps to enrich harmonic texture, allowing composers to add more color and depth to their music.
5. When combined with cadential 6/4 chords, ii6 enhances the harmonic function by providing a pathway towards resolution, contributing to effective voice leading.

Review Questions

• How does the ii6 chord function within a harmonic progression leading to a cadential 6/4 chord?
  • The ii6 chord serves as a predominant chord that naturally leads into cadential 6/4. By placing the third of the ii6 in the bass, it creates a smoother transition into the next chord, which is often V or V7. This movement establishes tension that seeks resolution, making it an essential part of effective harmonic progressions.
• In what ways can recognizing a ii6 chord enhance your understanding of voice leading in harmony?
  • Recognizing a ii6 chord allows you to see how it creates smoother voice leading by emphasizing stepwise motion in both inner voices and the bass. The bass note's movement from the ii6 to the cadential 6/4 creates a satisfying downward motion while maintaining close intervals among other voices. This understanding helps composers and performers create more cohesive musical lines.
• Evaluate the significance of using ii6 chords and cadential 6/4 chords together in building harmonic tension and resolution.
  • Using ii6 chords alongside cadential 6/4 chords is vital for building harmonic tension that leads to resolution. The ii6 sets up a predominant function that naturally transitions into the cadential 6/4, intensifying the expectation for resolution to the dominant. This combination allows composers to effectively manipulate emotional impact through carefully structured harmonic relationships.
