My questions are as follows ...
As A guitarist (Mostly electric with heavy distortion) what minimum knowledge of drums do I need to be able to create or chose drums beats that suits the song I am practicing.
I have seen many resources for dedicated drum lessons but those are lengthy and needs hands on practice with drum kit. Are there any good (free or paid) lessons or websites focusing on the basics of drums required for a guitarist?
Is there some set of very common drum beats that sounds well for most of the metal songs? If yes then how can I find them. Note that I am talking about the time I practice not the actual performance time.
I have heard that drum machines have some pre-existing beats/patterns. Is there are common set of drum patterns across most machines? If yes then what are they and can I find them without a drum machine? (Like guitar-pro files or other software)
Note that I already know staff notation and tablature for guitar. I am playing guitar for about 2 years and I don't have a friend who is a drummer. I am aware of backing tracks for songs and I am not talking about them. I need to have a basic understanding of drums so that I can chose which of the drum patterns will be good for the lick I am practicing.
