Predominant Triads

Definition

Predominant triads are chords that create a sense of tension and instability, preparing the listener for resolution to the tonic chord. They are typically used in the middle section of a musical phrase.

Analogy

Think of predominant triads as the "suspenseful chords" in a movie soundtrack. Just like how suspenseful music builds anticipation before an important scene, predominant triads build tension before resolving to the tonic chord.
