Compose & Embellish: Well-Structured Piano Performance Generation via A Two-Stage Approach
Even with strong sequence models like Transformers, generating expressive
piano performances with long-range musical structures remains challenging.
Meanwhile, methods to compose well-structured melodies or lead sheets (melody +
chords), i.e., simpler forms of music, gained more success. Observing the
above, we devise a two-stage Transformer-based framework that Composes a lead
sheet first, and then Embellishes it with accompaniment and expressive touches.
Such a factorization also enables pretraining on non-piano data. Our objective
and subjective experiments show that Compose & Embellish shrinks the gap in
structureness between a current state of the art and real performances by half,
and improves other musical aspects such as richness and coherence as well.Comment: Preprint. 4 pages, 2 figures, 4 table
