Well.... good info all...thanks. I've looked at the link that Peter listed before... it has several tuining, but not open C... and open D, tuned down, does not open C make, as near as I can tell....

Hmmmmm.... well, I'm just learing about alternate tunings, so I'm pretty dumb on this stuff... but, well... here's what I'm trying to figure out -

I am told that playing the un-fretted strings in open C tuning actually makes a D chord - is that right? I'm tuning it as: CGCGCD (didn't know there was more than one way!) So... I have a particular song that I play in D and want to try in open C because I like the sound of the tuning.... so I've figured out a few of the chords I need... but not all... maybe if I list 'em here someone can dig me out....

D D7 G Gm F#m Bm A7 Em7 D9

Now... I don't know... again, I'm new to these tunings... should I be using a differnt one? I'm just dabbling in DADGAD.... a few others.... heck, I don't know.... Any help appreciated!
