Haven't got in to O'Carolan much

I got to this tuning by using an old Martin Carthy one (DADEAD) and then simply taking it all down a tone as I thought at the time thats what Martin had done.
Course he hadn't and he uses CGCGCA - but I had got used to the c on the top string and couldn't be bothered to work out tunes again!!!

Lots of people seem to use this C modal (sus2) tuning CGCGCD - thats the way Nick Jones used to do it and more recently Chris Wood

Anybody interested in tracking down chords for alternate tunings?
I have found this online tool very useful

(not that there are many chords using C modal tuning but there you go)
