Users can play a short tune, or use a pre-recorded one, ask the keyboard to embellish it in one of four styles - jazz, classical, rock or pop - and then publish it on Soundcloud.Users can play a short tune, or use a pre-recorded one, ask the keyboard to embellish it in one of four styles - jazz, classical, rock or pop - and then publish it on Soundcloud.

He also said he struggled to see why the tool would appeal to professional musicians, many of whom already have a range of sophisticated tools for AI experimentation. A spokeswoman for Amazon said the device was intended for developers as a "fun and engaging way" to gain new skills.
And among more general users, it might fail to be seen as anything more than "a quick gimmick". Prof Collins said that, among more general users, it might fail to be seen as anything more than "a quick gimmick".

The central idea in all these cases, DeepComposer included, is that AI can capture key features of an art form and transform other material so that it shares those features too.The central idea in all these cases, DeepComposer included, is that AI can capture key features of an art form and transform other material so that it shares those features too.
