Automatical Composition of Lyrical Songs

We address the challenging task of automatically composing lyrical songs with matching musical and lyrical features, and we present the first prototype, M.U. SicusApparatus, to accomplish the task. The focus of this paper is especially on generation of art songs (lieds). The proposed approach writes lyrics first and then composes music to match the lyrics. The crux is that the music composition subprocess has access to the internals of the lyrics writing subprocess, so the music can be composed to match the intentions and choices of lyrics writing, rather than just the surface of the lyrics. We present some example songs composed by M.U. Sicus, and we outline first steps towards a general system combining both music composition and writing of lyrics.
