Nintendo blog, The Tanooki, has a really interesting article about the significance of the Golden Ratio (Wikipedia entry) in the music composed for the Legend of Zelda series. The article details what the Golden Ratio represents and how it relates to various compositions in the Zelda series.

It’s definitely worth a read and shows some of the nuances that are inherent in all aspects of video game development, including music/composition.
