Adaptive music

Adaptive music is music which changes in response to real-time events or user interactions, found most commonly in video games. It may change in volume, arrangement, tempo, and more. Adaptive music is a staple within the role-playing game genre, often being used to change the tone and intensity of music when the player enters and leaves combat. Music video games, in which a core gameplay element involves player interaction with music, also have fundamentally adaptive soundtracks.
