I have been trying out Dgd. I watched a couple YouTube videos on approaching it, which were helpful. I think that will really work for what I want to do.
Two obvious reasons why I can't just play a tune out of D, since that's what I'm tuned in. Number one is my fiddle player. If a tune is in G, then, well, it's in G. And some of those awkward tunes that obviously were written in a different key because they are either too high or too low for the middle voice of the instrument.
This will be really quick to tune to G when needed (my brain won't be so quick, so the first after re-tuning is always a throwaway, easy tune).
I will try to be content with this new challenge (on top of still being challenged with the standard tuning) for a little while before I start chasing the next tempting thing.
