Section 17.4 Analyzing Secondary Dominants

1. 🔗

   Stack the chord in thirds to determine the root and quality. If the chord quality is major (if a triad) or a major–minor seventh chord, go on to step 2. If the chord quality is not major or major–minor seventh, the chord is not a secondary dominant.
   
   🔗

   The chord in question is an F♯ major triad in first inversion.
2. 🔗

   Determine the note that would be a perfect 5th below the root of the chord you are analyzing. If this note would be the root of a diatonic chord, the chord you are analyzing is a secondary dominant.
   
   🔗

   Since B is $\hat{5}$, the F♯ major chord in first inversion is tonicizing $\text{V}$. Therefore the chord is ${\text{V}}^6/\text{V}$.
