If you're used to the G tuning, it's an option. If you're used to the A tuning, an easier solution that helps with flat keys is to have the second string in the high octave (if your string length allows for it). This gives you room to add more harmonies above bass notes in lower positions. Also, 5 of your six fingerboard strings would then be identical to modern guitar, so, if you come from that background, most chord shapes feel familiar.
I used to wince whenever I saw flat keys, but nowadays I don't find the ordinary re-entrant A tuning so much of a bother for the flats. Must be the jazz I attempt to crudely hack out every now and then. ;-) Chris [1]Sent from Yahoo Mail for iPhone On Thursday, March 17, 2016, 12:18 PM, Edward Chrysogonus Yong <edward.y...@gmail.com> wrote: Hi Lutefolk!
