Development of a Dynamic Chord Progression Generation System for Digital Game based on Neo-Riemannian Theory

Abstract

In today's demonstration, a dynamic chord progression generation system for games will be presented. Recent AAA titles, such as God of War(2018), make extensive use of chord progressions and modulations utilized in film scoring, which is different from both classical and pop music. One such compositional technique is the Neo-Riemannian theory. Based on this previous research with mathematical representation of music theory, we implemented the algorithm on Wwise and created an interactive demo in Unity.
