BT writes: In general, a game’s soundtrack should have a certain amount of cohesion between the different songs in order to tie all the various situations together. While other aspects of a game obviously work to achieve the same result and have an important role in doing so, music’s constant presence throughout an ever-changing game environment provides the perfect anchor for conveying emotions and ideas. There are many ways to take advantage of that fact to establish the connection, from having different tracks evoke similar emotions to using the same genre of music throughout. However, in my opinion, the most effective method is to build a multitude of tracks based on the same basic theme. There are a good amount of games that successfully fulfill that idea, but I find one of the best examples, if not the best, to be Banjo-Kazooie.
