An automated approach to choral part writing. (c2012)

Abstract

We present an automated model for distributing choral parts in the style of conventional four part writing, given a melody and the chord progressions. Our system is scalable and allows arrangements for more than four voices, if required. We use enumeration and support it with the constraints imposed by the nature of the problem. Our implementation can successfully transform most music pieces written for solo voices and instruments - old and modern - into singable a capella choral arrangements.
