Robots and humans will soon be living in harmony(和睦).A singing robot is being taught to create jazz with a human in a project.

Antonio Chella from Italy is working with a Telenoid robot. To start with, the Telenoid will be trained to follow the movements and simple sounds made by a human singer, and to connect music with different emotional states. Chella then plans to see if the robot can use these connections to create music.

Intelligence is often regarded as the ability to find connections between the existing things. But Chella suggests that a conscious(有意识的) creature should be able to go a step further and introduce new connections that result in the creation of something new.

Some jazz musicians say that they should have a mental library of musical phrases so that they are able to combine them in new ways. More importantly, however, this combination  happens in a state that is similar in a sense to dreaming. Chella wants to copy these states in a machine.

“This work raises interesting questions about the link between consciousness and music making,” says Philippe Pasquier, a musician and computer scientist. But he is skeptical about whether a robot musician needs a physical body.

Pasquier argues that the robots are faced with two challenges(挑战). Software that can copy Bach has already been developed. But interpretation（演绎）includes human’s different tastes and judgments. “What made the Beatles famous was not so much their works, but the fact that the interpretations of the works were wonderful,” he says.

It is not yet clear how a robot would go about interpreting music in a new way. But by copying humans and then learning to sing, Chella’s robot could provide clues.

What seems to be important is that human composers often listen to lots of music made by others. So Chella’s robot had better listen to those jazz standards first.
