Hello, welcome to this brief lesson!
First off, most metal is played in D or C tuning. Some bands tune down as low as B or A... For this lesson, we will be playing in C tuning (Two steps down).
Just a few things before we start...
1) Crank the Gain/Distortion on your amp.
2) Set the treble, middle and bass to your preference.
3) use a pick
Riff 1

Its a pretty basic riff. Easy to play, sounds good and is a gateway to much more. Play that riff a few times until you get the hang of it, once you do, try palm muting the open notes on the
C string.
