Abstract

 
 
 The feeling of immersion is an important aspect of gaming experiences. It can be greatly impacted by back- ground music. In this work, we investigate the use of algorithmically-generated background music as a mean to ge- nerate immersion in gaming experiences. For such, we developed two versions of the same game. One of them uses music written by a composer. The other uses real-time generated melodies based on a Markov chain. We evaluated the immersion level related to each of these versions using user questionnaires and performance measures. The re- sults did show only a small immersion difference between the versions. This indicates that algorithmic music can be a suitable option for game content generation. 
 
 
Highlights
Algorithmic music generation can be a method for fast content creation while preserving great variability
We evaluate the impact of algorithmic music on the feeling of immersion in digital games and compare it with that related to human-composed music
To evaluate how the background music can be related to the gaming experience, it is important to understand the concepts related to immersion
Summary
Algorithmic music generation can be a method for fast content creation while preserving great variability. Music in games are typically used as soundtracks recorded previously, which are associated to specific events, such as the beginning or ending of a level or scene. Such approach can make the music quickly become repetitive, which leads to a decrease in interest in the gaming experience (LIVINGSTONE; BROWN, 2005). In such environments, music generated by algorithms could help breaking the excessive repetition, offering a way to increase in the variety of the musical content. To evaluate how the background music can be related to the gaming experience, it is important to understand the concepts related to immersion
