In this article, a scheme to automatically generate polyphonic flamenco rumba versions from monophonic melodies is presented. Firstly, we provide an analysis about the parameters that defines the flamenco rumba, and then, we propose a method for transforming a generic monophonic audio signal into such a style. Our method firstly transcribes the monophonic audio signal into a symbolic representation, and then a set of note-level audio transformations based on music theory is applied to the monophonic audio signal in order to transform it to the polyphonic flamenco rumba style. Some audio examples of this transformation software are also provided.
