Song Analysis #3: Chord Progressions

I'm back again with another fun and exciting sound analysis. Today, I will be looking for chord progression in one of the songs that I chose. The song that I chose was:
Megumi Hayashibara - Tsubasa wo Kudasai (Give Me Wings)

Now, on to the chord progressions: I analysed the 1st Verse and  the Chorus for their chord progressions (This is in C Major by the way).

Verse 1: I-  viiº- vi- V- I- viiº- vii-V-    

Chorus: I-  viiº- vi- V- IV iii vi- viiº-   

One of the things that I noticed is that at the end of the first verse in terns of its chords, it ends on a 5 chord which is a nice sounding chord to end on because it is the dominant, or the Perfect 5th chord of C Major. On the other hand, the chorus of this song ends on a 7 chord, which is a lot farther than than a dominant chord. This add a different effect to the chord progression, wanting it to resolve to the 1 chord, this is called the leading tone, which is used in many songs. Another difference from the regular permutation of chords, because for most of this song descend chromatically, it follow the pattern backwards (for the most part).
