I examine how to create music for video games here. I embedded game music functions into the Automated Composing System. I mention how I developed these functions in this page.
RPG Theme music for Hero 
About theme music for Hero What are characteristics of a Hero music in RPG? They are "Brave", "Brightness", and "nimbleness." If you consider these characteristics in terms of Music, they mean "Major Key" and "Up-tempo." Therefore, 16 beat is used as rhythm. Usually, a hero starts his journey from a Castle, at which time a brass band of soldiers cheers him on. So, in Automated Composing System, brass sound is used for the melody instrument.
