This palm-mute accent pattern is in the key of A minor, uses some power chords, diads, and single note riffing.
Drums and tabs are attached to this post.
The pattern for this lesson is:
Mute, Mute, Open, Mute, Open, Mute, Mute, Open
On a side note - I just order a new pop filter. The one I'm using CLEARY isn't doing it's job. Should have better quality sound for the talking portions moving forward!
