Playing a set of chords it sounds decent but it sounds off... i cant tell,

capo 4th fret

2 0 0 2 3 3

a# c# f# c# f# b

Although it seems to come up with a different "answer" so maybe it wouldnt be as helpful as a working understanding of the theory behind chords

The A# and B two octaves apart will clash badly if you're just holding the chord as it is. if you can incorporate some melody so the highest or lowest note resolves, it might help.
