Hey guys, I've been studying modal theory a lot, and was hoping you guys could help me out.

What would be the best way to identify the root note/key from a song with a single note progression and/or riff? Would it just simply be plugging the notes in to the scale that fits?

And my second question, is introductory riff from "Crazy Train" in G# Phrygian?

Thanks, the help is appreciated.

Well the first note tends to be the root of the scale/mode

Then see how the rest of the notes fit around what that note is and what patterns they make

Well as far as i know the intro to crazy train is in F# Aeolian
And yes, you could just compare the notes to the scale and see what fits.
Sometimes people use the root note as the first note of the riff or melody, also if there are chords in the background analyzing them might give you some clue to what key it is in.
