Beethoven X AI completes the Tenth Symphony; premiered in Bonn

AI system

System: Beethoven X AI generative music model (Elgammal/Playform AI team)
Model: Not assessed
Release: Not assessed
Application developer: Ahmed Elgammal (Rutgers University / Playform AI) with Mark Gotham
Role: Not assessed
Configuration: Not assessed
Inputs and outputs: Not assessed
Autonomy: Not assessed
Workflow: Beethoven's surviving sketches for the Tenth Symphony. A generative model trained on Beethoven's complete works. Human selection, arrangement and orchestration by Werzowa and the musicologists. A sponsor and a professional orchestra willing to premiere the result.
Human oversight: Not assessed
Relation to AI: The model generated candidate continuations of Beethoven's sketches. Humans (Werzowa and the musicologists) selected, arranged and orchestrated them, so the AI contribution was generative input within a human-curated process. The vendor-side accounts (Elgammal in The Conversation; Telekom) and the orchestra's own program page agree on the premiere.
