Why these progressions work
Roman numerals describe chords by their position in a key, so the same pattern can be moved to C, F, B♭ or any other supported root. I–V–vi–IV uses the tonic, dominant, relative minor and subdominant. Try changing the third bar and listen for the shift in mood.
Natural minor usually has a minor v chord. The Harmonic minor preset intentionally raises the dominant third so V becomes major, producing a stronger cadence. That alteration is marked rather than silently presented as a natural-minor diatonic chord.
Practice tip
Start at 60–80 BPM. Play each chord on the first beat, then hold until the next bar. After four bars, try moving to a different inversion while keeping your hand near the previous notes. Use the Inversion Explorer to hear individual voicings.
