Human Coded Orchestra

Human Coded Orchestra is a new approach to enable a group of individuals to sing in harmony by using computed directional speakers. Group musical performance has been explored both in scientific studies and artwork. However, previous work has rarely dealt with group chorus. Human Coded Orchestra aims to realize group chorus without training. The present system employs many directional speakers, so that they will deliver different pitches to each participant to sing, according to their positions. Since participants only need to follow the pitch, this system makes group chorus easier. In the experiments using Human Coded Orchestra, participants succeeded in singing in harmony extemporaneously, and reported that they enjoyed both the feeling of singing. The system does not require any preparation on the part of singers, which opens up the possibility of practical application in the interactive performance area.
