Is the secondary dominant the same if my target chord is a major or minor of the same root?
Say my **target chord** is D major or D minor in two separate keys. For example let's say D major is in the key of G major (the V chord) and let's say the D minor is in the key of F major (the vi chord). Do they both have the same secondary dominant (A7)? the V7/V in the key of G is the same as the V7/vi in key of F? In other words, when I'm trying to figure out a secondary dominant, the V7 of a minor scale is just like V7 of a major scale, provided they share the same tonic (in this example D).
