“Music and video games: musical genre in its own right: From 8bit melody to a soundtrack. Far from acting as a backdrop or a sonic prop, music plays an increasingly important role in the world of video games. It provides a soundtrack that is directly involved in the gamers’ experience by means of their interaction with the graphics. This music can create atmospheres, climates and information that are essential for the success of any game, which means that this production is a parallel music sector that is crucial for the gaming industry.”
