I'm really a newbie and self-taught, so I beg your excuses in advance for a poor question. I'm following a course in game programming, and I come out with this progression that IMO should work as a pad for a SCI/FI ambient:
The last chord is written that way because it is voiced with C as the bass note. I don't know if it is correct--I hope it is.
The progression first was played with simple triads, and then I decided to add a bass. The bass line was at first
D-C-A-F. But this way, the progression "tastes" differently. I tried play it
D-C-A-C, where the lower note of last chord is
C instead of
F. I supposed that the bass should play the tonic of each chord, but it seemed to work better with the lower note (
C). Which of these two choices (
F) is theoretically correct?
Then other question--if I were to write this progression with Roman numerals, since I'm in key of
D, I would write:
I-VII-V-? What do I put in place of the question mark? How do I show with Roman numerals that I'm using a suspended chord?
