The English translations credit goes to Zelda Dungeon (as per the poster’s description). It seems this introduction appears before the title screen, although it is certainly possible it appears both before the title screen and when starting a new game (similar to Okami). We learn a great deal about not just the tone of Skyward Sword, but the Zelda Universe from these clips. So, again, do not watch if you want to avoid being spoiled. I will say the music does a great job of showing off what an orchestra can do for Zelda, so even if you’d rather no watch, I would take a listen. ENJOY!
