I've dabbled with open tunings in the past but never stuck with them.
I think this is because I was always too lazy to keep retuning the guitar and eventually gave up. My some what decadent solution to this is to have certain guitars permanently tuned to a particular tuning. I haven't got enough guitars to do this but I'm working on it.
The tunings I'm planning on using are
Double Dropped D
I'm having one guitar in standard tuning, another in Open G and will use the third for all the variations on D tunings.
I've already made a start on Dropped D and Open G and have relearn some songs in those tunings (more about this in a future blog).
My plan is to have some songs in each tuning which will give me between 20 and 30 minutes playing time for each tuning.
A longer term goal may be to understand more about the theory for these tunings and learn the chord shapes fo these tunings. At the moment I don't have a clue about it.
