You might think that the latest pop hit is created by a machine rather than a human being.Actually,getting artificial intelligence to understand many aspects of music is easier said than done.Describing things like musical structure,harmony,and form can be difficult enough when speaking with somebody who did not study music theory,let alone a machine.
A study out of China examines if AI can be taught to recognise some of these features and then to compose music itself.To do this,they used an AI enhanced with a programme called the Harmony-Aware Hierarchical Music Transformer (HAT),a system that can turn musical data into machine-readable parts and then review those parts for harmony,form,and other musical qualities.The system was then fed hundreds of pieces of human-composed piano music to learn what pop music is supposed to sound like.
To see how well it could perform,the researchers asked the AI to complete a song.They fed the AI the opening to Guang Yin De Gu Shi,a real Chinese pop song,and then measured how closely it was able to match the song in terms of generating melodic segments (旋律片段) of similar length.For good measure, they also gave the same task to two other music-generating AIs which were less advanced than HAT.While HAT outperformed its computer rivals (对手),the segments it created were disconnected from each other and clearly not human-made,though they were roughly the same length as those in the human-made tune.
“There is still a huge gap between the HAT-generated pieces and the real works,” conclude the authors,suggesting that a future study can attempt to create an AI that can “polish” the music it creates to close that gap.
