From E Major to C Major. I listened to the main theme "Small Two Pieces" (Sung by Joanne Hogg) which had the latter key and I was wondering why it was done differently for its flying theme. Different feelings in the moment for different vibes I suppose. Either way, enjoy!

Composed by Yasunori Mitsuda. Among many of his pieces, some songs of this game are truly amazing. Brought me to Xeno-tears.
