<p><b>From recent decades' digitization have emerged a myriad of techniques for mapping musical life identifying patterns in sound or musico-cultural practices and compiling labels names tags and classes on an unprecedented scale. </b> <p/>Proliferating genre catalogs in the context of digital platforms and the conjunction of genre with notions of for example mood and activity are among the consequences which challenge prevailing scene-based and identificational understandings in musical genre studies. This book answers to this challenge. Centering on the concepts of musico-generic assemblage and abstraction it offers new perspectives on musical genre fit for current times but with the potential for also reconsidering historical cases.</p>
