I have recently been exploring chords in the Locrian mode. Down to the flattened 5th and 9th degrees, I have come up with some pretty bizarre sus chords. This got me thinking: Are such chords still recognised as sus chords, in spite of their altered degrees?
A couple of examples:
F sharp, G, C- Can this be described as an F sharp sus flat 2 flat 5?
F sharp, B, C- Can this be described as an F sharp sus 4 flat 5?
m3 V sharp 9
One chord that threw me off was this one: F sharp, A, C, B.
To me, this should be seen as F sharp diminished with an added 11. However, I have seen it described as F sharp sus 4 flat 5 , sharp 9. So, when does a m3 become a sharp 9? Or are both ways of naming this chord as valid as each other?
