Tuning In Triads as oposed to 5ths

I am interested not only in d-tuning but also in harmonic and closer
nit tunings that the standard tunings. Guitars and basses usuly can
not play triad chords only the progressions. While a piano can do
triad chords all day long. Currently I am trying out A C E G B D and
D drone A C E G B on my guitars and I love the crushing sound of bar
chords and the harmonies I can estract frome the closer proximity of
semi tones
