Talk:This Day Aria, Part 1/@comment-4919288-20120425033107/@comment-5051208-20120425123008

For the first half of "This Day Aria" the cadence when Chrysilis is singing is A minor - C# minor which is vi - i. When Cadence is singing, it is A minor - C# major which is vi - I. For the 2nd half of the song, the piece moves to G# major (dominant of C#) and Chrysilis finishes on a V - i ending on C# minor, while Cadence finishes with a perfect cadence of V - I. Neither of these are interupted or perfect cadences, instead what you are hearing is the difference between Crhysilis finishing on the minor of the root key, while Cadence is finishing on the major. The BBBFF song does indeed have an interupted (deceptive) cadence in it. You can hear it at the end where she ends on a minor chord instead of falling to the major root.

I can fully transcribe the song by ear if you want to see how it works (I quickly worked this out while sitting at my piano). Brilliant song btw.
