I'm currently studing and learning about functional harmony and chord progressions.
I tried the chord progression i - v - VII - iv (A natural minor scale : Am - Em - G - Dm7/A) and get a nice and melancolic mood, for my ears.
But I don't really know if this chord progression make sense tecnically.
It's normal to use a Minor dominant in a natural minor key? Or should I use an Major dominant to turn the scale harmonic?
