Experts from the Institute of Cyber Intelligence Systems at the National Research Nuclear University MEPhI (Russia) are currently developing a virtual composer assistant that will be able to analyze the emotional state of music composers and follow their logic. Despite the high level of development of music theory, the process of creating music is still hard to formally algorithmize, since it is inseparably linked with the emotional experiences of the composer. This aspect of the creative process is of particular interest to experts in machine intelligence.
