A Major Dominant Chord (A):
The A major chord (A–C#–E) acts as the dominant chord in the key of D minor (which is the relative minor of C major). In jazz, it’s common to use the dominant chord from the relative minor key to create tension and lead back to the tonic (C major) chord.

So, here’s the twist: "Short Dress Gal" indeed uses the A major chord (from the relative minor key) as its dominant chord, creating a bluesy, New Orleans feel. It’s a delightful departure from the expected Gmaj7!
