What is the chord progression and also the technique used in this rock riff?
Example of the riff being played
Relative novice here in music theory, forgive me. There's this fantastic rock riff, and I'm trying to figure out what they're doing in it. I know it's some simple chord progression, with the chords broken up and played highest note first, then lowest, then middle to give that great sense of progression. My problem is that I can't figure out which chords are being used. I've tried every combination of major chords, minor chords, seventh chords, suspended chords, and all their inversions, but for the life of me, I can't find anything that fits the notes.
Can someone help me figure this out? And is there a name for what they're doing here?
Edit: I just realized. I think arpeggio is the right term used to refer to this? Is that also the term they use in rock?

This is a riff based on the C#m (or E major) pentatonic scale rather than a single arpeggio as it doesn't just outline a single chord.
In terms of the chords/harmony implied by the bassline once the rest of the instruments come in, I'd say it's playing:
| A - - - | B - - - | C#m - - - | E - - - |
| A - - - | B - G#7/C - | C#m - - - | E - - - |
... or something like that. Because of the chromatic bass walk in bar 6, that second chord in bar 6 can be debated. Is it a G#7/C (played frets X3454X)? Is it some sort of diminished chord? Play what you want. Don't follow the bassline and just stay on B. Play what I suggest. Whatever works for you. This is how I'd transcribe it anyway.
This riff in E consists of the tones do re mi so la (Penta tonic scale ionic)
It fits well above the Chords A B c#m E without the thirds:
so in these 4 chords you have to play only the notes: AE, BF#, C#G#, EB
Concerning the riff:
as described above in doremi syllables - you can use also the numbers for E=1, F#=4, G#=3, A=4, B=5
Then the riff will be:
1-5-6-2-5-6-3-1-2-5-1-2-6-1-2
or in doremi:
do-so-la-re-so-la-mi-do-re-so-do-re-la-do-re
if you look at the tones with accents you will identify the scale:
1-2-3-5-6 = do-re-mi-so-la (ionian pentatonic scale)
A pentatonic scale is a musical scale with five notes per octave, in contrast to the more familiar heptatonic scale that has seven notes per octave
look up:
en.wikipedia.org/wiki/Pentatonic_scale
and no: this is not an arpeggio, just a as you say a decomposition of scale tones
while an arpeggio is rather an decomposition of a chord (broken chord) as playing on a harp: arpeggio
