Many of you keyboard player's know how to solo the songs from bodom.
For ex. COB-Children Of Bodom keyboard solo.
So you could help me out, tell me how do you do it , where your fingers stand
how did you learned it, if you've got video post me a link.
 
Sorry, but i wouldn't know. I'v played keyboards for a while but i never tryed to do the COB solos. And i still need to find the notes for them over the internet.
