Welcome back to my four-part article series presenting videos and helpful references to aid aspiring game music composers in understanding how interactive music works.

Interactive. Now let’s turn our attention to a more complex example of horizontal re-sequencing as demonstrated by the interactive music of the Spore Hero game from Electronic Arts.
