Musical Rhythm in the Age of Digital Reproduction presents new insights into the study of musical rhythm through investigations of the micro-rhythmic design of groove-based music. The main purpose of the book is to investigate how technological mediation - in the age of digital music production tools - has influenced the design of rhythm at the micro level. Through close readings of technology-driven popular music genres, such as contemporary R&B, hip-hop, trip-hop, electro-pop, electronica, house and techno, as well as played folk music styles, the book sheds light on how investigations of the musical-temporal relationships of groove-based musics might be fruitfully pursued, in particular with regard to their micro-rhythmic features. This book is based on contributions to the project Rhythm in the Age of Digital Reproduction (RADR), a five-year research project running from 2004 to 2009 that was funded by the Norwegian Research Council.
