Musical synchronism and mixed music: from written time to produced time 
Musical synchronism is essential to interpreting written music. Performance musicians are skilled in their capacity to achieve real time synchronization and coordination, with multiple musicians each playing their part to produce a coherent result. To successfully elicit a context of interaction between musicians and the machine raises interesting challenges for artificial intelligence and the practice of mixed music. This article explores musical synchronism in mixed music, looking at the practical, artistic and technological aspects, and presents recent and historical points of view drawn from subjects of musical research related to this question.
