I recommended the DAA tuning because the method for getting harmony out of it is so simple - index finger on the melody string, ring finger one fret behind on the D string, with the minor exceptions as noted. It is a good way to get used to strumming, brushing, picking, sounding out, and finding the first note of a new song.

I fingerpick a lot, but when I brush, I brush away.

However, there is always "the dreaded bum-diddy strum," which is back and forth.

I also like DAA because I'm an alto, but I rarely play and sing at the same time. Too hard.
