hey I'm writing a folky/angry song. I'm new to using new tunings but wonder if there's any way to tune my guitar to make it sound a little meaner. Hope you know what I mean.

Something where I can still use the chord shapes I know hopefully. Anything like this around? I've heard of the idea of tuning it 'down a step', not sure how it works though.

D standard or half a step down. I use half a step down for my acoustic stuff because i think it sounds alot nicer

ps down a step is to D standard, half a step is to D# or Eb

I use DADDAD for a few songs but its certainly not 'meaner'. Just gives a very full sound from a 12 string playing combination chords or full/half barre.
I pick up my guitar and play
