Okay, I'm working on a couple riffs to go in the verse section of a song, so not a great deal of melodic motion in the riff.

I'm in drop D, and I'm pedaling on the low D.

At the end of each bar I play a short single note passage that consists of A, C, E, F, C (in that order).

I'd like to start composing a solo for this piece with the same feel as my single note line.

So, what scale options do I have to choose from if I want it to remain in the same key my riff is in? I'm getting better with theory, but I'm not at a point where I can figure out which scales I can use by listening to a 4 note passage.

I guess if you want to include the low D pedal tone, the notes would be A, C, D, E, F.
That sounds like a pentatonic, but which one?
It's d minor. And it's diatonic. There are no minor seconds in pentatonic scales.

EDIT: Strictly speaking, there are some pentatonic scales which do contain minor seconds. Example: in scale (used in Japanese music). Just found it on wiki.

If you pedal the D, most likely D minor.
And no, Guitar Hero will not help. Even on expert. Really.
Cool. Thank you.

I'd have figured it out eventually, but it was a lot faster just to ask someone.
