Adaptive music
 | This article needs additional citations for verification. (November 2014) |
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.[citation needed]
History
[edit]Adaptive music was first[citation needed] 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.
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.[1][2][3][4]
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 or Kingdom Come: Deliverance.[5]
Horizontal and vertical techniques
[edit]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. Many games employ a mixture of these techniques in the creation of their soundtracks.[citation needed]
Horizontal re-sequencing
[edit]Horizontal re-sequencing is the technique by which different pieces of music can be shuffled between according to game events.
The most basic re-sequencing technique is to simply crossfade between two sections of music. When the game scenario changes, the first piece of music is faded out while the second piece fades in. Another technique is phrase branching; in this case, the change to the next segment starts when the current musical phrase has ended.[6] A more elaborate but flexible technique involves dedicated transitions. These transitions are triggered when switching between different segments, allowing for the changes to remain musically fluent and therefore keep with the flow of music.[citation needed]
Vertical re-orchestration
[edit]Vertical re-orchestration is the technique of changing the arrangement of an ongoing piece of music according to game events. Instruments may be introduced or removed from the piece live in response to player interaction.[citation needed]
Generative and algorithmic music
[edit]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.[7] Ape Out is another notable example, with a procedurally generated jazz percussion soundtrack that changes based on the intensity of the gameplay, as well as the actions and movement of the player. [8]
Soundtrack switching
[edit]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 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
[edit]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. Dead Space 2 is another example of this, in which the music during gameplay appears to be arranged into four layers, each are a stereo track identifying with a distinct level of fear. Each layer of music is then either individually or collectively mixed "on-the-fly" depending on a variety of variables in the game, such as distance the player is from Necromorphs.[9] 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
[edit]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
[edit]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.[10][11]

Frustrated with the state of music in games at the time, two composers at LucasArts Peter MccConnell and Michal Land created one of the first adaptive music systems, called iMuse. iMuse (Interactive MUsic Streaming Engine) let composers insert branch and loop markers into a sequence that would allow the music to change based on the decisions of the player. The iMuse engine was one of the first significant contributions to interactive music for video games. Its importance in shaping many of the techniques that you see in video games today cannot be overemphasized. (...) Other excellent iMuse titles includes Grim Fandango (1998), which features an incredible jazz-based soundtrack composed by Peter McConnell. (...)
