Procedural mixed-initiative music composition with hierarchical Wave Function Collapse

Pál Patrik Varga and Rafael Bidarra

An example of using prototypes. A prototype yellowblue-yellow-yellow is defined (top), and associated to the cyan state. Therefore, every cell on the higher-level layer that collapses to the cyan state will impose the contents of the prototype on the lower-level layer, by default. Note the repetition of the yellow-blue-yellow-yellow "theme"

Mixed-initiative music composition systems are sought after by both amateur and professional musicians. A well-known PCG algorithm is Wave Function Collapse (WFC), which has recently been extended with various mixed-initiative capabilities [6]. So far, WFC has mainly been used for generating video game levels, textures and graphical patterns. This demo presents and illustrates an approach for an interactive WFC-based music composition editor.
