贝多芬的《第十交响曲》是他逝世后留下的遗稿。然而，现在人工智能技术已经可以通过这些片段续写出一首完整的钢琴曲了。

Ludwig van Beethoven is undoubtedly one of the greatest musicians that ever lived. The German composer and pianist completed 722 musical works—including nine symphonies （交响曲）—despite being completely deaf during the last decade of his life. Unfortunately， the master died while still working on his 10th Symphony. Now， a team of musicians and scientists have used artificial intelligence （AI） to complete the artist's final masterpiece.

Dr Matthias R？觟der first came up with the idea to complete the masterpiece in 2019. The director of the Karajan Institute in Austria thought it was a suitable way to celebrate Beethoven's 250th birthday in December 2020. He began by persuading an international team of music experts to help him with the task. They included music composer Walter Werzowa and Dr Ahmed Elgammal， the creator of an innovative（创新的） AI technology for the art market.

Elgammal and his colleagues started the process by familiarizing（使熟悉） the AI software initially with a broad range of classical music， and then narrowed it to just Beethoven's works. Meanwhile， Werzowa and his group tried to understand the rough sketches and the handful of notes that detailed Beethoven's plans for the 10th Symphony.

The team then began the task of feeding the AI software musical notes from the unfinished composition. Elgammal says that since music is very structured and mathematical （精確的）， AI can predict the next note reasonably accurately. However， it starts to deviate （偏离） from the central theme after a few notes. To stay true to Beethoven's original composition， Elgammal's team sent Werzowa hundreds of AI-created musical note variations （变奏） every evening. Werzowa would listen to them and then select the one that he thought was closest to what the artist would have written. The AI team would add the music and rerun the software to produce the next suggestions. And piece by piece， the team was able to complete Beethoven's 10th Symphony！

Not surprisingly， the AI-generated masterpiece is causing some controversy. Critics believe technology should not be used to replicate the human creative process. Elgammal and his team agree with their position and say their AI software is not out to replace humans—it is just a tool to help artists to express themselves in new ways.
