ŠT—v/Abstract

The goal of our study is to popularize active ways of enjoying music, especially jam sessions. To reach the goal, this paper proposes a novel environment that helps unskilled people easily enjoy jam sessions. To achieve this environment, there are two problems: insufficient skill of beginners and the difficulty of finding session members. Although some attempts have been made to solve these problems in previous studies, none of them have dealt with both problems mentioned above. In this study, we achieve a new system, called Openism, that solves both of the two problems. For the former problem, our system provides a virtual music studio on the Internet, which enables users to find session members from worldwide musicians and to enjoy a remote session with them through the Internet. For the latter, our system supports insufficient skill for improvisation of beginners by automatically detecting musically unnatural notes and correcting them to musically natural ones in real time. We implemented this system on a Linux server and Windows clients and confirmed that this system could solve the problems of insufficient skill and the difficulty of finding members.
