This book is the first anthology of writings about the emerging subject of artistic experimentation in music. This subject, as part of the cross-disciplinary field of artistic research, cuts across boundaries of the conventional categories of performance practice, music analysis, aesthetics, and music pedagogy. The texts, most of them specially written for this volume, have a common genesis in the explorations of the Orpheus Research Centre in Music (ORCiM) in Ghent, Belgium. The book critically examines experimentation in music of different historical eras. It is essential reading for performers, composers, teachers, and others wanting to inform themselves of the issues and the current debates in the new field of artistic research as applied to music. The publication is accompanied by a CD of music discussed in the text and by an online resource of video illustrations of specific issues.
