Huawei completes Schubert's 8th Symphony

By Kirsten Scholte, 06 February 2019

For almost 200 years Schubert's 8th symphony has been known as his unfinished work because the piece was never completed. Until now... Huawei combined the power of AI with human expertise to complete the ‘unfinished symphony’.

With a substantial delegation of, among others, Dutch press and other influencers, we travelled to London. There, in the Cadogan Hall, the completed piece was brought to life by the English Session Orchestra. Huawei worked on the composition with composer and Emmy winner Lucas Cantor.

Artificial intelligence...

With this project Huawei wants to show what artificial intelligence (AI) is capable of, using the dual NPU (Neural Processing Unit) of the HUAWEI Mate20 Pro smartphone. By analysing the timbre, pitch and meter of the existing first and second movements of the symphony, the AI model generated the melody for the final and missing third and fourth parts.

“At Huawei we are always looking for ways in which technology can make the world a better place. So, we taught our Mate20 Pro smartphone to analyse an unfinished, nearly 200 year old piece of music and finish it in the style of the original composer”, said Walter Ji, President CBG, Huawei Western Europe. “We used the power of AI to extend the boundaries of what is humanly possible and see the positive role technology can have on modern culture. If our smartphone is intelligent enough to do this, what else is possible?”

...and the human brain

Lucas Cantor: “My role was to draw out the good ideas of AI and fill in the possible gaps to ensure the final result was ready to be played by a symphony orchestra. The result of this collaboration with AI proves that technology offers incredible possibilities and the significant and positive impact it can have on modern culture.”
