Hi Darren, here are two variants of double C tuning. eCGCD. Sometimes called "half shaved" tuning. It has a lovely rich C major sound with the first string fretted at 2nd. Works for any tunes clearly in C major. Then gCGCD# gives a really nice totally open C minor chord as the base. It is an old but little used tuning (ie not my invention) I use this for Darling Cory, Texas rangers, wayfaring stranger too. And neither is very different to double c, they are not too difficult to get to grips with, as long as you know double c. Open C is good for C major tunes too. gCGCE. I play "hard times come again no more" in this. Have fun, Andy
I use AdaDE. Isn't this double d tuning,or am I missing something.. I am an Irish trad player, tenor banjo, mandola, transitioning to CH, Our tunes are usually in G and D and this tuning really suits their fingering. Best wishes, Micheal.
