In video games, adaptive music (also called dynamic or interactive music) is background music whose volume, rhythm or tune changes in response to specific events in the game.

Video Adaptive music

History

Adaptive music was first used in the video game Frogger by Konami (1981), where the music would abruptly change once the player reached a safe point in the game.

After this, its next uses in major video games were Wing Commander, Monkey Island 2: LeChuck's Revenge and Ultima Underworld: The Stygian Abyss. It has since been used in such games as Mushroom Men and Guitar Hero.

Many of LucasArts' games used the iMUSE dynamic music system, from Monkey Island 2 onwards and including games like Dark Forces, Star Wars: TIE Fighter, Full Throttle and Grim Fandango. The iMUSE system is notable in that it segues seamlessly between different pieces of music rather than having an abrupt cut.

Later games which made notable use of similar dynamic music systems include the Deus Ex and Freespace series of games.

It is also a staple of the role-playing game genre, often being used to change the music when the player is in combat, such as in The Elder Scrolls III: Morrowind.

Horizontal and vertical techniques

The music in video or computer games and certain films is meant to draw the audience through a storyline using two distinct techniques: horizontal re-sequencing and vertical re-orchestration. Horizontal re-sequencing is the method by which pre-composed segments of music can be re-shuffled according to a player's choice of where they go in a storyline or environment. vertical re-orchestration is the technique of changing the mix of separate parts of an ongoing loop of music in relation to a player's movement within the narrative of a game. Games, such as Halo 2, employ a mixture of these techniques in the creation of their soundtracks. Street Fighter II and Mario Kart DS are examples of games which change the music's tempo under certain circumstances.

Algorithmic music

Instead of relying on individual tracks of audio such as in horizontal re-sequencing and vertical re-orchestration, some games automatically generate their content on the fly, such as the case of Spore, which uses an embedded version of the music software Pure Data to generate music to certain cues such as the addition of parts to your creature throughout the game.

Soundtrack switching

Games may also employ two soundtracks and mix between them, as in the case of FTL: Faster Than Light, which has an "explore" and "battle" version of each track. When the player is in battle with another ship, the audio fades into the "battle" version. This "battle" version is usually reasonably similar to the "explore" version with the addition of drums and similar dark timbres. Because of this, the transition is rather smooth and doesn't ruin the player's immersion. This is in contrast to the invincibility theme in the Super Mario series which aims to stick out, making the change sudden and obvious.

Interactive blending of music and sound effects

Some video games, such as Rez and Extase, use sound effects triggered by the player's actions that are automatically delayed to stay in synchronization with the background music and that blend well with the music. This creates an interactive musical landscape in which the player's actions actively and instantaneously take part, enhance, shape and influence the music. On the box of Extase, such a music system, created by Stéphane Picq, was advertised with a sticker as "Interactive Music System."

As goal of the game

Music games such as Sound Shapes use adaptive music as the goal of the game. As the player gets better at the game (and collects more 'coins'), the soundtrack (which is entirely composed of the melodies and beats created by these 'coins') intensifies as a sign that they're doing well.

Other occurrences

Adaptive music was used notably in theatre in 2010 in the play 'Dom Duardos' from Gil Vicente, co-produced by Companhia Contigo Teatro and Grupo de Mímica e Teatro Oficina Versus, with music by Pedro Macedo Camacho.
