Composers, performers, listeners, critics and theorists all play vital roles in the creation of music culture; yet often each group can appear to hold widely divergent views of a musical work's aims and effects. As the title indicates, this book examines the parts played by these groups and the interaction between them. These absorbing essays offer new insights into our understanding of music making in all its senses, and suggest future ways of approaching works whether as a composer, performers or listener.
