IThink what you are after is the modal sound getting rid of the note in the chord that makes it major or minor,G modal is this 550030,dmodal is 000230.the beauty of this tuning in my opinion is its flexibility,youcan also easily play major and minor chords
Richard Bridges b minor is alovely chord,if youslide this shspe up to 5 fret you have d6 or bminor7[chords often have two names]this is very closely related to bminor and under some circumstances can be substitued for it 057700,here is another b minor with a different voicing 0,9,0,11,0,0.this time your b minor chord bf#d,is voiced df#df#bd,Richard Bridges b minor was voiced dbbf#bd,these voicings or different inversions are important to understand,because they can make your playing more interesting.
if you understand how chords and dyads work,all you need do is draw your fingerboard out and discover it for yourself for nothing.
you need to learn modal chords [or dyads]find out what asus4chord is.its this [D SUS 4is DGDA],the third note of d major is sharpened a semitone d f#a,becomes d g a,also use modal 7 dadacd[no f#,then you will start to be on yourway to getting the sound of open tunings beloved by KateRusby and many others long before her,you will of course on occasions,want to also use major and minor chords.hope this helps.Dick Miles
