Since Darwin, the putative direct role of natural selection in the emergence of human music has been a topic of great debate. A key hypothesis, whose empirical testing is crucial to this debate, is whether the ability to produce rhythmic patterns is a human specific trait, or shared with other non-human primates. During this Exchange Visit, I intend to build an electronic device that enables chimpanzees (''Pan troglodytes'') to produce sounds through its physical exploration and manipulation, allowing to test the rhythmic production hypothesis. There are two advantages in using such an electronic device: (1) it is possible to precisely record physical variations in the sensor for later analysis and (2) the experimenter can decide about the acoustic feedback properties. This results in a flexible experimental paradigm, which allows for testing a wide range of rhythm and auditory cognition hypotheses by experimentally altering the sounds the device produces. The same device and paradigm will be used to test children, thus providing comparative data on a highly controversial topic. | Since Darwin, the putative direct role of natural selection in the emergence of human music has been a topic of great debate.

Summary
Since Darwin, the putative direct role of natural selection in the emergence of human music has been a topic of great debate. A key hypothesis, whose empirical testing is crucial to this debate, is whether the ability to produce rhythmic patterns is a human specific trait, or shared with other non-human primates. During this Exchange Visit, I intend to build an electronic device that enables chimpanzees (Pan troglodytes) to produce sounds through its physical exploration and manipulation, allowing to test the rhythmic production hypothesis. There are two advantages in using such an electronic device: (1) it is possible to precisely record physical variations in the sensor for later analysis and (2) the experimenter can decide about the acoustic feedback properties. This results in a flexible experimental paradigm, which allows for testing a wide range of rhythm and auditory cognition hypotheses by experimentally altering the sounds the device produces. The same device and paradigm will be used to test children, thus providing comparative data on a highly controversial topic.
