Richard Dawkins's formulation of the meme concept in his 1976 classic The Selfish Gene has inspired three decades of work in what many see as the burgeoning science of memetics. This study is the first musicologically-orientated attempt systematically to apply the theory of memetics to music. In contrast to the two points of view normally adopted in music theory and analysis - namely those of the listener and the composer - the purpose of this book is to argue for a distinct and illuminating third perspective. The perspective is that of the (selfish) replicated musical pattern itself, and adopting it is central to memetics.
