Music, a profound expression of the human experience, is built upon intricate patterns that humans have spent centuries trying to understand and recreate. Consequentially, Hierarchical Wave Function Collapse was proposed as a novel model for procedural music generation, which organizes musical constraints within a three-level hierarchy. However, music with melody but no rhythm, is like a text with all characters but no spacing. This research aims to create rhythm procedurally by exploring existing representations and combining the most effective elements to propose a simple but comprehensive rhythmic model. Though not all-powerful, the proposed model accommodates varied measures and motifs. By implementing it, the research evaluates its efficiency and limitations, identifying the types of music it cannot generate. This study aims to contribute a tool for mixed-initiative music creation, expanding procedural music generation with a nuanced approach to rhythm.
