Enjoy! Beethoven's unfinished X. symphony recreated with the aid of artificial intelligence! It premiered on October 9th, 2021!
"The master left behind around 200 fragmentary sketches of the Tenth Symphony, presumably in four movements. A human composer in 1988 completed two movements, for which more source material was available, so the team set out to compose two more.
Matthias Röder, director of the Karajan Institute, which promotes uses of technology in music, led musical experts in deciding how the sparse contents of the remaining sketches might fit into a symphonic format. Meanwhile, Rutgers University professor Ahmed Elgammal built an AI system to expand the sketches into a fully orchestrated score.
Elgammal adapted natural language models to music, he told The Batch. The system included components that generated variations on melodic themes, harmonized the results, created transitions, and assigned musical lines to instruments in the orchestra.
He trained the models first on annotated scores music that influenced Beethoven, later on the composer’s own body of work. To train the melodic model, for instance, he annotated passages of theme and development. Then he fed the model thematic material from the sketches to generate elaborations on it.
The system eventually generated over 40 minutes of music in two movements. ...
Behind the news: In 2019, Huawei used AI powered by its smartphone processors to realize the final two movements of Franz Schubert’s unfinished Eighth Symphony. The engineers trained their model on roughly 90 pieces of Schubert’s work as well as pieces written by composers who influenced him. A human composer cleaned up the output, organized it into sections, and distributed the notes among various instruments. "
