Watch the Nu Metal Ostinato online guitar lesson by Angus Clark from Hard Rock Survival Guide: Rhythm

C# minor, A, E, B. This chord progression is the centerpiece of well over 100 tunes that have made it to the top 100. What I want you to focus on is the pocket and the bounce during the main section of the song. When you've got the gain up like this, you have to tame the beast. Don't let the strings squeak or the harmonics poke their heads out. You're either playing or there is silence. It's simple stuff but you've got to play it right. This example sits in stark contrast to the Grunge examples in that way. For the section where you're playing the ostinato figure in sixteenth notes you'll get a chance to work on your picking (I'm using alternate picking cause that's how I roll), your right hand muting, and you'll want to watch how I've worked out the fingering in order to facilitate playing the part cleanly. One real takeaway from this is that working out your fingering is an important part of getting the job done. Once you've got your picking, fretting, and synchronization up to a decent level of proficiency, if you come across a part that you can't get to sound right, you should look for an easier way to play it. The problem is probably not your technique, it's that you're not applying your technique appropriately. Work out the fingering so that the left-hand/right-hand combinations and string crossing line up with stuff that you can already play.
