I am watching this video on youtube: http://www.youtube.com/watch?v=sFYbdcuPPo0

And could someone tab out these arpeggios and tell me what they are?

One starts at :53 seconds in

THe other is a riff that starts at 1:19 and goes for a few seconds and ends with really loud high pitched scream. Can someone tab that and tell me how to do that scream?

Another is a classical thing he does at 1:29-1:40, can someone tab that?

Last thing is can someone tell me the scales or tab them out what scales he used on this thing?
