Ok, I hope this is the right thread area...

I write a little bit of music at the moment, but I would like to start playing more Classic Rock/Hair Metal type stuff

I play rhythm guitar

I was wondering if there were any special techniques, chords, or rhythm styles that I should learn to play that type of music
look at a whole list of songs you think are in this area (maybe make a playlist) then look up the riffs and structure and see what the songs all have in common. You'll learn from them trust me and you'll probably be able to come up with something that could fit in with that playlist just make sure its not stealing hahaha i worry about that a lot.
