VIDEOS: Huawei uses AI to finish Schubert's 'Unfinished Symphony' after 197 years

On February 4, 2019, Huawei unveiled, in what it claims was a first, the final two movements of Schubert’s famous Symphony No. 8 with the combined power of AI and human expertise.

In a live performance at the "iconic Cadogan Hall" in London of Monday, February 4 2019, Huawei’s AI combined with human expertise finished Schubert’s "Unfinished Symphony"
after 197 years.

Huawei said that "despite numerous attempts it remains one of the most intriguing pieces of unfinished symphonic music of all time".

The company also added that its "completed version of Schubert’s Symphony No. 8 was created by running an AI model benefitting directly from the processing power of the dual NPU (Neural Processing Unit) in the Huawei Mate20 Pro smartphone – designed specifically with AI-based tasks in mind.

"Analysing the timbre, pitch and metre of the existing first and second movements of the symphony, the AI model then generated the melody for the final, missing third and fourth movements.

"Huawei then worked with Emmy award-winning composer Lucas Cantor, to arrange an orchestral score from the melody that stayed true to the style of Schubert’s Symphony No. 8."

Larking Huang, Managing Director of Huawei Australia Consumer Business Group said: "At Huawei, we are always searching 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 to finish it in the style of the original composer.

“We used the power of AI, to extend the boundaries of what is humanly possible and see the positive role technology might have on modern culture. If our smartphone is intelligent enough to do this, what else could be possible?", Huang concluded.

Composer Lucas Cantor said, “My role was to draw out the AI’s good ideas and fill in the gaps to ensure the final output 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.”

The final, Huawei-completed piece was be brought to life with a live performance at the iconic Cadogan Hall in London on Monday 4th February.
