So, lately I've branched off from my traditional style (more classic rock and such) and gone into garage rock and punk. I watched videos of nick valensi and I saw CJ ramone from the ramones tonight(!!) in a show and i noticed that both his guitarist (who was the producer of the ramones!!!) and valensi grip their power chords weird.

Usually, what I do is this:

index, ring, pinky, all pressed down with index slightly barred to mute lower strings. middle finger up.

What I noticed is that most of these guitarists(and others too) put ALL of their fingers on the strings. I can't figure out how to do that reliably! where does the middle finger go? is it resting on the low e? when I do that I end up muting the a string. It kind of works when playing e string barre chords but otherwise I screw it up. also, is the pink and ring playing the 5th and the octave? or is one barring both? which one?

grip is visible in 1:08 of this video

Looks to me like he's fretting the root with his index, 5th with his pinky and allowing the middle and ring fingers to sort of flop over. I don't think he's playing the octave.
There's no need to change the way you play power chords, index, ring, pinky is perfectly fine.

Okay.. thought i was doing it wrong.

Yeah, it's really clear in that video that the middle and ring fingers aren't fretting anything, they're just slightly curled over the top of the neck.

Hmmm.. Never really seen it before. But I learned chords without ever watching anyone. Is my way okay or is that way more versatile? I can see it working for a form power chords (as the fretting is so close already), but for e form power chords my way seems to be better cause I can drop my middle and I'm there(same for a minor form)
