Lesson focused on the rock rhythm playing. Great workout for one direction picking (downstrokes), combined with palm muting. Let's get familiar with a few most common concept of creating riffs in this particular genre. Make sure You push your right hand to it's strength limits, so it would make guitar sound tight and sharp, even on the medium gain amount. Notice that in main video guitar has been recorded twice and panned one 100% left and the other 100% right(double tracking). This trick helps to squeeze more power out of backing guitar tone. These days it's a kind of must for anything from rock to metal. Otherwise single guitar track may not be able to transfer the amount of energy you would usually feel while playing your part live, on the amp. Double tracking is also a great way to verify how well you can execute the licks. Precisely played part with double tracking should make you able to recognize each note while both guitars play. Any timing or articulation issues will immediately come out. It's a great way for a self-test.
