This is a rock guitar lick based on the A Minor Scale with the inclusion of the A# note. It can make a good legato exercise in your guitar practice schedule. Give it a try with a metronome for a couple minutes a day and see what you think.
For some more advanced study material check out the awesome guitar madness of Yngwie Malmsteen or Tony MacAlpine ( who is now in Steve Vai's band). Cheers.
