An algorithm completes Schubert's "Unfinished Symphony" with a mobile phone


The Chinese technology company Huawei presents today in the Cadogan Hall of London a "complete" version of the "Unfinished Symphony" by Franz Schubert composed from a artificial intelligence algorithm who has used the power of one of the firm's mobile phones.

The software analyzed the tone, the tone and other characteristics of the first two movements of the "Symphony in B Minor, D. 759", composed by the Austrian musician in 1822.

From that information, the program generated a melody for the last two movements of the piece, which Schubert left incomplete.

Subsequently, the engineers of Huawei collaborated with musician and producer Lucas Cantor to give final touches to the piece and obtain a score "faithful" to the style of the original work.

"My function was to bring to light the most interesting ideas of artificial intelligence and fill their gaps so that the final result could be interpreted by a symphony orchestra," the musician said in a statement from the brand.

"The result of this collaboration with artificial intelligence shows that technology offers incredible possibilities and that it can have a significant and positive impact on modern culture," he added.

The director of Huawei in Europe Walter Ji maintained, for his part, that the objective of this work was "to expand the horizons of what is humanly possible and to check the positive impact that technology can have on modern culture".

"If our smartphone is smart enough to do that, how far can it go?" The manager asked.
