The defining cadence: E major contains G-sharp, which leads directly upward to A and makes the return to i feel decisive.
Harmonic Minor Chord Progressions
Minor Progressions With a Stronger Dominant
Harmonic minor raises the seventh degree of natural minor. That creates a leading tone and turns the V chord into a major or dominant chord, giving minor-key progressions a much stronger pull back to i. The sound can be dramatic, tense or uplifting depending on voicing and arrangement.
A longer minor phrase that saves the raised-seventh tension for the final chord, making the next tonic arrival more pronounced.
A compact dramatic cadence that works well when the arrangement needs a quick lift into the tonic without a long progression.
The raised seventh changes one crucial function
Natural minor has a minor v chord, which does not create the same semitone pull into the tonic. Raising scale degree seven gives V a major third and creates the leading tone, so the dominant can resolve with much more direction.
You do not need to use the raised seventh in every chord. Many effective progressions stay close to natural minor and introduce the harmonic-minor note only when V appears. That contrast is part of what makes the cadence feel special.
