Sounding Off brings together a selection of essays on philosophy of music written by Peter Kivy - the leading expert on the subject. The essays fall into four groups, corresponding to Kivy's major interests. Part I contains two essays on the nature of musical genius. In Part II, three essaystake up the subject of authenticity in performance, and explores what Kivy terms 'the authenticity of interpretation'. Part III contains four essays concerning the much discussed issues of musical representation and musical meaning. Finally, Part IV consists of three essays on the 'pure musicalparameters': these are essays on 'music alone' or 'absolute music' -music as the pure, formal structure of (sometimes) expressive sound. Eight of the eleven essays presented here are previously unpublished, and the book includes two appendices which provide Kivy's responses to criticism.
