In an interview with Original Sound Vision, Nintendo composer Koji Kondo has revealed that The Legend of Zelda: Skyward Sword will involve "new musical gameplay elements.".
Kondo isn't in charge of Skyward Sword, but that hasn't stopped him revealing some details about the music, having worked on the music with Hajime Wakai.
Our next title, Skyward Sword, also has a wide variety of impressive songs, and it has new musical gameplay elements,Hajime Wakai is in charge of the music, but I also participated in making songs. My composition tools are an electronic piano and a Mac. We use orchestras for a few different songs where we feel that doing so is appropriate.
The recent Skyward Sword trailer shows a Harp in Links inventory, this could be the instrument used in Skyward Sword's gameplay. How exactly it will be involved in the game is yet to be revealed however.
What do you think about Link using a new instrument? How do you expect it to be used in the game?
