## Where should I start with secondary dominants & applied chords?
The curriculum places Chord Inversions & Figured Bass before this module. Review those topics if they are unfamiliar. The first lesson is “Tonicization”: Briefly treating a chord as a temporary tonic. The order is a study guide, not proof that every learner needs the same pace.

## How long is the secondary dominants & applied chords module?
The 5 listed lessons total approximately 77 minutes of material. That estimate describes lesson content, not the practice time needed to become comfortable with tonicization, v/v, and the emotional color of applied harmony. Revisit one task at a time and use feedback from a teacher where physical technique is involved.
