The following is an excerpt from this Wikipedia article:
[The Lydian cadence] is so-called because it evokes the Lydian mode based on its final chord as a tonic, and may be construed with the chord symbols VII♯6/3-I (if the final is taken as a Lydian-mode tonic) or III6/3-IV (if the final is taken as a scale degree 4 in major).
I'm having immense trouble trying to wrap my head around VII# -- which after looking around I've come to the conclusion that it's just a sharpened VII chord.
But... wouldn't VII# = I ?
If, in C major,
VII = B D# F#
VII# = C E G
? I have to be misunderstanding something or else would that not mean the cadence goes from itself to itself, only 1st inv. to root position?
I'm thoroughly confused and would be grateful for some guidance...
