In music, the listener has expectations of how the sound of a song will progress throughout its duration. These expectations are either met or thwarted by the cadences that come at the conclusion of phrases throughout the piece. Cadences in music serve to present a narrative to the listener, increasing and resolving tension until the song’s conclusion. This demonstration will show a method of generating novel chord progressions with these features using the Haskell programming language. The demonstration will walk through the generation process with code examples and sample output, illustrating a grammar-based approach for implementing abstract, traditional harmonies in Haskell.
