Yngwie

This is a pretty killer lick. It is just before the main solo in Liar by Yngwie Malmsteen. Take a quick listen to the arpeggio section before the solo here:

Yngwie uses the arpeggios:

G#o  G#o  Am  Am 
G#o  G#o  Am  Am 
A∆   Dm   G∆  C∆ 
Bb∆  Am   F∆  E∆ 

And we get the impression that the sequence is split into the following three sections:

Section 1 (x2):  G#o  G#o  Am  Am 
Section 2:       A∆   Dm   G∆  C∆ 
Section 3:       Bb∆  Am   F∆  E∆ 

And it looks like we are in the key of A minor (check out chords from minor keys). Looking at the numerals for the key of A minor we get:
